Best Cordless Power Tools To Maintain After Doomsday

This article is part 3 of 12 in our series that cumulatively includes details on the vast amount of battery powered capabilities a prepper can easily maintain after a Doomsday event.  

In this article, written from a prepper's viewpoint, learn why you will likely need cordless power tools after commercial AC power is no longer available plus which features you should consider before purchasing anything.  Keep reading to learn which power tools could be maintained during Doomsday with just portable solar power, and the order of importance of each tool.

Why you might need Cordless Power Tools in Doomsday

If society were to collapse due to any reason, i.e., an EMP, economic or financial collapse, virus pandemic, food shortages, super volcano, or some other cause, the world and your neighborhood are going to turn chaotic and very dangerous within a very short time as the unprepared quickly run out of food and water.  When and if that happens, and commercial AC power is no longer available, you may soon realize that you wished you still had access to use certain power tools.  

Cordless power tools will help you to fortify your property, house or bunker, and will enable other important survival capabilities.  We will release a new article in July 2020 called "How To Turn Your Home Into A Fortress To Survive Doomsday!" that shows how preppers can "harden" their home or bunker and more easily defend it before & after SHTF.  

You can continue to have cordless power tools and their capabilities if you simply obtain them prior to a Doomsday event along with foldable solar panels and portable solar generators (power stations), which we recommend in our 10 part series linked near the bottom of this page.  

Without solar panels and solar power stations, your cordless power tools will cease to work after their batteries are drained and AC commercial power is still non-existent.

If society ever collapses, a prepper is going to need power tools more than ever to build useful things, barricade parts of their house or bunker, create defensive positions, board up some windows & doors, build a green house, animal pens (chickens, ducks, rabbits, etc.), and basically other things that require cutting, grinding, sanding, drilling, installing, removing, inflating & prying open things. 

Our own personal Doomsday planning includes a lot of work doing the prior mentioned types of work plus creating & enhancing shooting positions, hunting platforms & blinds, installing cargo nets & camouflage nets for added security, terminating barbed wire on concrete foundation walls & wall studs, demolition for re-purposing wood & much more. 

Small portable solar generators can easily provide the power to keep all of your cordless power tool batteries charged.  Foldable solar panels can keep recharging the solar generators hundreds or even thousands of times.  Solar Panels coupled with Portable Solar Generators would be immensely helpful during Doomsday.

NOTE:  Please be sure to invest in hand tool versions of these power tools as well.  Speed of building things will likely be a critical factor in a SHTF situation and power tools accomplish work much faster than hand tools.  However, you definitely should have the equivalent hand tools in your stockpile.

Top Considerations When Choosing Cordless Power Tools

1. Choose cordless power tools that use Lithium batteries.  Lithium battery powered tools are much better than NiMH battery sets as Lithium powered tools deliver more power and longer run times in a lighter package, the batteries last longer, and lithium battery chargers require less power, which is super important to conserve power provided by solar panels & solar generators.  

2. Brushed vs. Brushless cordless power tools.  Not long ago, brushless motors were only available in contractor grade brands such as DeWalt, Makita, and Milwaukee.  Now brushless motors are available in more modestly priced consumer power tools such as Kobalt, Porter-Cable, and Ridgid.  

Brushed motors drain batteries faster than brushless motors.  Brushless motors adjust to the level of resistance they encounter, require less energy, operate with less friction, are more efficient and they have fewer moving parts.  Because brushless motors have no brushes, you never need to think about replacing them so brushless tools are going to last longer (perhaps twice as many years as brushed tools).  

Brushless tools are advertised to run up to 50% longer run times on the same Amp-Hour batteries.  However, brushless tools are typically more expensive than brushed versions.  Still, brushed tools from reputable brands will typically last last several years and take a lot of abuse.  If you do not think you will need to use power tools very much, then brushed tools may be perfectly suitable for you.  We recommend brushless tools if you can afford them, but definitely take price into consideration. Below is a YouTube video for a comparison test of brushed vs. brushless tools.

Are brushless tools worth the extra money?

3. 12V versus 18V versus 20V versus 60V.  You can choose 12V DC if you want power tools lighter in weight.  Many of the 12V DC Cordless Power Tools are very good options.  Most people today prefer 18V, or even better 20V DC Cordless Power Tools because they have better power and can handle bigger jobs better and faster.  Greater than 20V adds even more power for all day every day heavy contractor use.

4. Amp-Hour (Ah) Battery Sizes - The higher a battery's Amp-Hours (Ah), the longer the run time for the same power tool.  1.5 Ah & 2.0 Ah Batteries will get the job done on smaller less power intensive jobs and in a large number of "typical" jobs they are more than adequate.  4.0 Ah, 5.0 Ah, and 6.0 Ah batteries are better for larger jobs and high power consuming jobs like using a circular saw all day.

We recommend the 5.0 Ah batteries (or higher). In the long run, you'll probably be happier with 5.0 Ah as there's a big difference in power when doing a task like cutting a metal pipe with a reciprocating saw where the 2.0 Ah or smaller batteries will feel like they are bogging down.  Not knocking the smaller Ah batteries.  It's good to have some of those hand for lighter weight and smaller jobs.

5. Cost - If you cannot afford to purchase a contractor grade lithium brushless Cordless Power Tool Combo Set, you could opt to to purchase just one or two tools and then add to them later as you can afford them, or you could purchase a less expensive brushed combo kit or start with one or two of those tools.  Also, besides having interchangeable batteries, it is usually less expensive to buy Cordless Power Tool Combo Sets versus individual tools, and then add on individual tools with or without batteries & chargers. 

6. Stick to the same brand & series.  If you are buying your first cordless power tools, or if you need to upgrade your older models to brushless & lithium tools, be sure to stick to the same brand and series for your new tools so that your batteries are interchangeable, unless your old tools have NiMH batteries which means it is time to start transitioning to lithium.  If you really like and trust a particular brand such as Bosch, Makita or Milwaukee then by all means stick with them as those are 3 very good brands.

Our Recommendations On Brand

We are recommending DEWALT 20V MAX XR Cordless Power Tools due to contractor quality, lithium batteries, brushless motors, plus the availability of a Cigarette Lighter DC powered charger.  The MAX XR is the latest Brushless version of their 20V cordless power tools.  "XR" stands for "Extreme Runtime".  

Dewalt is one of the best power tool brands in the world and due to its high-quality products has dominated the international tools market for decades. The prime characteristics that separate Dewalt products from other brands are their durable build, efficient operation, and reliable, long term service.  

IMPORTANT NOTE:  The following top 10 priority list is by Tool Type (Cordless Drill #1, Cordless Circular Saw #2, etc.).  You can substitute different brands and/or quality for each choice.  We are not trying to rank the exact best brand for each tool type because then you end up with a set of multiple different brands in the list and you need to stick with the same brand & series if possible.  

DeWalt makes high quality & reliable contractor grade cordless power tools.  If you prefer a different brand or lower quality/less expensive set or even a higher quality set of DeWalt FlexVolt 60V Max Cordless Tools, then go with what works for your needs & budget.  

All of the Cordless Power Tools listed below are DeWalt 20V Max XR tools that could be add-ons to a 20V Max XR combo set.  As another example, if you did go with DeWalt 20V Max XR for a combo set, if you purchased an "add-on" DeWalt FlexVolt 60V Max Circular Saw, plus you purchased a set of 6.0 Ah, 9.0 Ah, and/or 12.0 Ah Flex Volt 20V/60V batteries, then those FlexVolt batteries would work in all your 20V Max XR and FlexVolt 60V Dewalt cordless power tools.

DeWalt FlexVolt 20V / 60V  9.0 Ah Batteries

As a final note, it is easy to debate the order of the following list.  We had a really hard time and many people would prioritize the tools differently and understandably so.  You can make your own judgement. It's actually fun and a challenge thinking about what order you would put them in, or if you could only have 3 cordless power tools after a Doomsday event, which three would you take.  Our #10 may be your #1.

 

Our Top 10 Picks for the Best Cordless Power Tools for Doomsday Preppers

1. Cordless Drills

2. Northern Tool

3. International Tool

2. Cordless Circular Saws

 

Cordless Circular Saws are easy to use, very efficient and powerful, and are astonishingly flexible, practical and fast.  The portable circular saw is designed to cut lumber and boards to size. Most models come with an adjustable T-guide for straight cuts.  

Prepper's Viewpoint:  Even though different versions of hand saws could theoretically replace a circular saw, the speed of cutting boards and plywood would be like 100 times faster with a power saw.  With many other chores to do, the circular saw is #2 on our list for getting wood cut fast to build things.

3. Cordless Chainsaws 

Cordless chainsaws can cut up firewood and branches, they can make rapid cuts in lumbar where precision is not an issue, they can quickly harvest lumber and boards to be repurposed, and they can be used indoors!  They are also much quieter than gas chain saws.  During Doomsday, solar power and cordless power tools will outlast gas power tools.  

Prepper's Viewpoint:  For quick demolition of most wood to re-purpose, nothing will be faster than a cordless chain saw.  Add to that the ability to quietly and quickly cut up small trees and branches for firewood, the cordless chainsaw is #3. The ability to use indoors is also a big plus.

DeWalt 20V Max XR - Compact Cordless Chainsaw - Model # DCCS620B

• Low kick back 12" Oregon Bar and chain: for construction and outdoor cutting applications
• High efficiency Brushless motor: maximizes run time and motor life
• Tool free chain tensioning and Bar tightening knob
• Compact and lightweight design: Only 8. 8 lbs.

2. International Tool

4. Cordless Reciprocating Saws

 

Reciprocating Saws are the tool for you on demolition day, with the versatility to cut metal, wood and plastic.  The reciprocating saw is a portable and powerful saw that can be used at all sorts of angles for demolition and rough-cut purposes. More often, the reciprocating saw is used for its brute strength, to saw through walls or ceilings, creating openings for windows, plumbing lines, or other purposes.  This is a compact saw that can get in tight spaces easier than a larger saw.  

Prepper's Viewpoint:  There is not a more versatile tool for demolition of just about any material including metal pipes and bars to re-purpose than a cordless reciprocating saw.  The cordless chainsaw might be faster on wood and handling larger cuts, but it does not have the versatility of cutting metal and to get into tight spaces like the reciprocating saw.  The reciprocating saw is #4 on our list.

5. Impact Drivers 

 

Impact Drivers are used primarily to only drives screws, but they have more power than a cordless drill to get tougher jobs completed easier.  An impact driver can drive larger screws quicker and more efficiently than a cordless drill, making it a better choice for projects requiring lots of large or long screws. You can fit an impact driver with ¼” hex-shank drill bits for making holes, but they are generally not as precise as drilling holes with a cordless drill.  Impact drivers are usually available in 1/4", 3/8" or 1/2" chuck versions.  The Impact driver does a better job not stripping screw heads compared to a cordless drill.  

Prepper's Viewpoint:  In line with needing to build things quickly, the impact driver is much better than a drill for efficiently and quickly driving larger screws and a high quantity of screws and without stripping screw heads, making it #5 on our list.

6. Cordless Angle Grinders 

 

Angle grinders are versatile tools that can grind or cut metal, tile, concrete, stucco and pavers, rout out mortar, plus they can sand, polish and sharpen blades, cut or grind steel, make quick work of rust and loose paint removal.   

Prepper's Viewpoint:  Another tool in line with needing to build things quickly, depending on the attachment, the angle grinder can cut, grind and shape materials such as metal, stone, and concrete.  They can also remove paint and rust, plus polish metal by using wire wheels and cups.  The angle grinder makes #6 on our list.  The YouTube video below explains the difference between the DeWalt DCG405 (slide switch) and DCG406 (paddle switch).  

DeWalt 20V Max XR - Angle Grinder - Model # DCG405B

• Brushless motor requires no brush changes.
• Kickback Brake engages when a pinch, stall, or bind-up event is sensed.
• Brake stops wheel in 2 seconds or less on average
• Power Loss Reset® prevents accidental restarts.

7. Cordless Sanders 

Prepper's Viewpoint:   Cordless sanders can smooth out rough and splintered wood.  The last thing you need in Doomsday is to cut wood and build things only to have them introduce splinters as unnecessary medical issues.  This makes a cordless sander #7 in our list. 

Note:  This Cordless sander's Included dust tube & dust bag (shown below) only allows room to use batteries 5.0 Ah and under. Available for purchase as an accessory is the DeWalt N684701 dust port for batteries 6.0 Ah and over (Ref: Instruction Manual, p. 12).  However, a 5.0 Ah battery is already overkill on a sander.

DeWalt 20V Max XR - Cordless Variable Speed Sander - Model # DCW200B

• Brushless motor provides runtime and efficiency to get the job done
• Variable speed control from 8, 000 - 14, 000 OPM to match the speed to the application

Prepper's Viewpoint:   If you need to drill into brick or concrete, there is no other choice than a hammer drill.  They also drill wood and metal in a larger, more powerful, more expensive version of a normal cordless drill, makes a cordless hammer drill #9 in our list.  If you are only going to have one drill, we would consider bumping the Hammer Drill up to #1 in our list.  It is so large and powerful (and not compact) but it is more versatile than a normal drill in that it can drill into concrete with the hammer function (which can also be turned off so this is just a powerful drill).  

DeWalt 20V Max XR - Cordless Hammer Drill - Model # DCD996B

• High performance 3-speed transmission for fast application speeds and improved run time
• High efficiency brushless motor delivers up to 57 percent more run time over brushed

1. Amazon 

NOTE:  Also consider the DeWalt 20V Max XR - Cordless Hammer Drill - Model # DCD998B.  The DCD998B is the newer version replacing the DCD996B and they are compared in the YouTube video above.  We could only find the newer DCD998B on Amazon and in a combo package with a carrying case, charger, and 8.0 Ah Battery.
NOTE:  Also consider the DeWalt 20V Max XR - Compact Hammer Drill - Model # DCD796B.  The DCD796 is more compact and is quite a bit less powerful than the DCD996.  The DCD996 has a fancier chuck and three speeds instead of two speeds for the DCD796. The DCD796 seems to be a pound or so lighter and is more compact.  The DCD996 features a powerful brushless motor that supplies a maximum 820 Units Watts Out (UWO) for a faster application speed.  The DCD796 supplies 460 UWO max in comparison. The direct links to compare prices of the less powerful 2 speed Cordless Hammer Drill #DCD796 are:  Amazon (includes case, charger and two 2.0 Ah batteries), & International Tool (includes case, charger, and two 2.0 Ah batteries).  We could not locate the DCD796 with just the Tool Only.

• Integrated XPS cross cut positioning system for better accuracy and visibility
• Adjustable stainless steel miter detent plate has 10 positive stops
• Oversized bevel scale
• Compact, lightweight design (31.6 bs.) for easy transport and storage

• Includes wood clamp and blade changing tool (attached on saw)
• Integrated light illuminates cutting area
• Up to 175 2x4 cuts on one charge
• Single bevel saw - only tilts in one direction

11. Rotary Tools (i.e., Dremel Tools)  

Rotary Tools (i.e., Dremel Tools) - Corded or Cordless Dremel tools are very versatile and will provide intricate grinding, cutting, sanding, sharpening, carving, polishing, drilling & engraving capabilities.  They are excellent for working in small or hard-to-reach spaces.  

They can also sharpen blades such as for knives or chainsaw blades.  Cordless would be better than corded in a Doomsday scenario, but some smaller corded versions can be powered directly from a Solar Generator Power Station.  If you already have one of these in a corded version, just check the maximum or continuous 110V AC Watts.  Otherwise, purchase a cordless version.  You can find less expensive rotary tools, but they do not have the build quality or durability of Dremel in our opinion.

Prepper's Viewpoint:  Whenever you wish you had a smaller drill, saw, grinder, polisher and/or intricate level work, the Dremel Tool should be your go to tool.   The Dremel Tool makes #11 on our list.  

Dremel 8220-1/28 Rotary Tool with Flex Shaft Attachment

If Cost Is Just Too Much & You Already Have A Cordless Drill That You Do Not Want To Upgrade

If you just have an older NiMH cordless drill and do not want to upgrade it but want to add a less expensive lithium powered circular saw, we recommend the Popoman 20V Cordless Mini Circular Saw that is pictured below.  We purchased one with a 4.0 Ah battery and charger and and it comes with a laser guide which is really nice.  It has a brushed motor, is lightweight and it is a beast considering its size.  We put a Diablo 4-1/2 in. x 24-Teeth Framing Saw Blade on it that we bought from Home Depot and it easily cut 2x4 boards and plywood easily for several hours.  

There is a YouTube video below, of a slightly different version with a 2.0 Ah battery.  The one that is linked above has a better trigger and 4.0 Ah battery versus the one in the YouTube video.  Extra 20V 2.0 Ah batteries are available at this link.  The "extra" 2.0 Ah battery is shown in the tool below, while the original 4.0 Ah battery is shown in the charger.

Extra Tips When Buying Screws To Stockpile For Doomsday

The Flat Head Exterior Wood Deck Screw is an important type of screw to stockpile for Doomsday.  It is a versatile screw for building things inside and outside with plywood & boards (2x4, etc.).  We have 5lb. boxes (or more) on hand of exterior deck screws in all lengths.  

A lot of people automatically reach for Phillips head screws when they are buying a box.  When choosing which screws to buy, try screws with heads other than Slotted (worst) and Phillips Head (2nd worst).  Phillips head screws are easy to strip the heads out.  If you have options like you do when purchasing exterior deck screws, instead try Torx (i.e., Star) Head (better), Square Head (even better), or combo Phillips-Square Head (best) or Hex Head (also best) especially when driving a lot of long and/or thicker diameter screws.  

When you buy a box of screws like the Phillips-Square Head as an example, they usually include the appropriate bit in the box of screws.  With Phillips Square Head (if you can find them), the bit will slide in easier when engaging the tool to the screw head, but then it will stay in place with the square fitting.  You can't beat it in a deck screw.  If you can't find them use the plain Square Heads.  They are a just a little slower to engage the bit in the screw, but they are not going to strip out like a Phillips Head.   

Check Amazon, Home Depot & Lowes for Phillips-Square Head Exterior Wood Deck Screws.  We usually have better luck finding them at Home Depot in 1 lb., 5 lb., or 25 lb. boxes (but only online - for some reason they do not stock them in the stores).

Phillips-Square Head Exterior Wood Deck Screws Are The Best Head To Use With Your Drill / Impact Driver

Galvanized Metal Roofing Screws like the Acorn International Galvanized Metal Roofing Screws are another important screw to stockpile for Doomsday.  They come in different lengths in bags with 250 screws.  

We bought a couple of bags of the #9 x 1" for attaching galvanized corrugated metal roofing as one of our building materials for use after a Doomsday event.  We will release a new article in June 2020 called "How To Turn Your Home Into A Fortress To Survive Doomsday!" that shows how preppers can "harden" their home or bunker and more easily defend it before & after SHTF.  Galvanized corrugated metal roofing is included as one of many solutions and it needs the proper screws to attach it.  

With Hex Head screws, you need to purchase the appropriate size Nut Driver Bits, such as the excellent 1/4 in. x 1-7/8 in. Shockwave Magnetic Nut Driver Bit (3-Pack) set we got at Home Depot.  They have a magnetic head to hold the screws securely to your cordless drill or impact driver during installation.
