DeWalt DC970K-2 vs. Black and Decker GCO18SB-2

Good morning!

Today we’re going to take a look at a couple different popular cordless drills. We will compare the DeWalt DC970K-2 and the Black and Decker GCO18SB-2. Both are well known companies and have been around for a long time so you know both will be around for repair or replacement if need be. I have personally used both and have had good luck with both. Both are reliable and proven to me to be good quality. Now let’s get into the meat and potatoes of these two drills.

Both drills are 18 volt. Both have keyless / ratcheting chucks for ease of use. Both come with charger and storage bag. That’s about as far as this comparison goes. That’s not to say both do not have their own value and their own place.

In order to have a two battery system for constant use with the DeWalt, your cost would be $73.00 + $63.01 bringing your total cost to $136.01.

If you are looking for a drill to for a regular, daily, heavy use, then the DeWalt is probably the drill for you but be prepared to shell out around $136.01 + S&H

On the other hand, if you are starting to build up your tool arsenal or just simply use one of these drills on a limited basis, the Black and Decker will probably work just fine for you for several years and will only set you back around $51.98 + S&H


The difference between purchasing the two with comparable options, is around $84. It’s ultimately your decision whether you need rugged or durable, extra batteries or a 1/2″ or 3/8″ chuck.

Hopefully this comparison is helpful in your decision to purchase your cordless drill.
