Black and Decker BDCR20B Review

The Black and Decker BDCR20B is a great reciprocating saw for light-medium tasks, such as pruning trees and cutting plastic or light metal.


The BDCR20B is cordless and is powered by a 20V MAX battery.

The BDCR20B is powered by 20V MAX batteries.

The bad news is that the saw doesn’t come with a battery or charger.

I get that some people already have the batteries and don’t want to be forced to buy more.

But lots of people don’t – so why not offer the saw with or without batteries?

Anyway, rant over… 🙂

The good news is that these batteries can be reused with a lot of other Black and Decker 20V MAX tools, such as their trimmers, circular saws, impact drivers and drills (the LDX120C is our favorite).

So as long as you plan on getting more compatible tools, buying 20V MAX batteries is a good investment.

Amazon recommends the Black and Decker 1.5Ah battery, which has good ratings and is great for short DIY projects.

However, if you’re going to be working on larger DIY projects and don’t want to stop to recharge the battery, I recommend the Energup 2.0Ah batteries. These will last longer than the 1.5Ah battery and you get two of them for almost the same price as the 1.5Ah battery 🙂

You’ll also need a battery charger if you don’t have one already. If not, check out the Black & Decker BDCAC202B. It’s Black and Decker’s 20V fast charger and can recharge a battery in 45 minutes.

Cutting Ability

The saw is capable of up to 3,000 Strokes Per Minute (SPM), which compares favorably with the higher-priced saws that we have reviewed.

The Black and Decker BDCR20B can cut plastic and light steel.

But don’t be intimidated by all that power, the BDCR20B comes with a variable speed trigger. This lets you control how fast the blade is moving, so you don’t use too much power and get into trouble.

Another nice safety feature of this saw is the electric brake.

Once you let go of the trigger, the blade starts to slow down until it stops moving. On older reciprocating saws, this could take a few seconds. That could be a safety issue because because would forget that the blade was still moving and have an accident.

The BDCR20B solves this problem by engaging an electric brake as soon as you let go of the trigger. This stops the blade moving very quickly, which helps to prevent accidents.


A Black and Decker BDCR20B review wouldn’t be complete without talking about blades. After all, a saw is no use without a blade!

Changing a vlade on the BDCR20B is quick and easy.

First of let’s talk about stroke length as this can greatly affect how well the blade cuts.

Stroke length describes how far the blades moves back and forth as it is cutting. And as you’d expect, the further it moves, the more it’s cuts.

The BDCR20B has a 7/8 inch stroke, which honestly is a little shorter than other saws we reviewed.

Is that a problem? Perhaps if you’re going for the reciprocating saw world speed record (if such a thing exists). But in the real world it just means that you’ll spend a few seconds longer cutting something – depending on what it is.

As for the blades themselves, the BDCR20B comes with a blade that’s suitable for pruning and cutting light metal.

Now even the best blade in the world will get dull over time and when it does – it’s time for a replacement.

My personal favorite is the Irwin Tools piece blade set. It’s comes with 11 blades that are suitable for cutting composition materials, plastic, pipe, carbon steel, and stainless steel.

And if you need a pruning blade recommendation, check out the Porter-Cable 9 inch pruning blades. They’re the best selling reciprocating saw blades on Amazon for a reason 🙂

Size and Weight

A Black and Decker BDCR20B review wouldn’t be complete without talking about it’s size and weight.

After all, how big and heavy a saw is can make a huge difference in how easy it is to use. Because bigger, heavier saws are more difficult to use.

Battery powered saws tend to be shorter than AC powered ones. And the BDCR20B is no difference at 3.44 inches wide x 7.13 inches tall x 15.63 inches long.

That makes the BDCR20B about 4-10 inches shorter than other saws we reviewed. That’s great because it means that you can fit the saw into some tight spots that other saws don’t fit into.

As for weight, the BDCR20B weighs in at 3.8 pounds without the battery. Even with a battery, the saw only weighs 4.6 pounds 🙂

Compare that to AC powered saws which typically weigh anywhere from 7-8 pounds!

That might not sound like a lot but and the end of a busy day of pruning, those extra pounds will weigh heavily on you.

The BDCR20B is great for pruning trees.

Should I buy the Black and Decker BDCR20B?

If you’re looking for a lightweight saw for pruning trees and cutting light to medium materials, this is the saw for you.
