It’s just the truth: whether it’s for around-the-house, assembling furniture, or building things, everyone needs a reliable drill. “But Ted, there are so many drills. There are simply too many. I could really use your help even though we haven’t really talked much lately… and… I love you…” Okay, the best cordless drill is the DeWalt DCD791B 20v MAX XR Brushless Drill/Driver. But you should read on before buying.

My Experience

My first drill was a $15 corded Drill Master from Harbor Freight and it was awful and failed within a year. My second drill was a $40 corded Ryobi (D43K) which failed within 2 years (but to be fair, I was using a wide drill bit through some thick wood on a hot day — probably more than it was designed for). After these drills, I decided to level up to heavier-duty, and also cut the cord. 

I spent a lot of time researching drills and cordless tool ecosystems and settled on DeWalt because they have a great reputation for quality and a large selection of compatible cordless tools. Also, the kit with batteries and a charger was on sale locally, and I found a guy on Facebook Marketplace who was selling other compatible new DeWalt tools for pretty cheap. I’ve used this drill to repair/install things around the house, assemble furniture, and do woodworking things and it hasn’t let me down, even under heavy loads drilling wood and metal. The battery life is great. I’m happy with my choice and I know it will last a long time. I’m recommending the kit with two 2 Ah batteries because if one battery runs out, you can switch to the fresh one while the empty one charges.

Does Ted Approve?

Yes

You can’t go wrong with this drill. It’s not the cheapest option, but you truly get what you pay for, and a solid drill is a great investment.

Where To Buy

I recommend buying it as a kit with two batteries and a charger, around $160 at the time of writing:

Other Options

There are some other options depending on sale prices and your budget. I’m linking to the kits that include batteries/a charger that I would get if I didn’t get what I got. The kit will have a different model number since it includes more than just the drill.

  • Cheaper: DeWalt 20v MAX Drill/Driver Kit (DCD771C2). This is the brushed model that will be cheaper but is slightly less efficient than the XR/brushless line. Usually around $99.
  • Budget Pick: Ryobi ONE+ 18v Drill/Driver Kit (P209D). Cheapest option and good enough if you’re just doing light- to medium-duty things. Usually around $49.
  • Other brands: Milwaukee, Makita, and Bosch all make tools that are on par with DeWalt’s quality with similar pricing, and you can’t go wrong with any of them. I picked DeWalt for their large variety of compatible tools and recommendations from others. More info regarding cordless tool platforms on this page.
