5.0 out of 5 stars Nice short & powerful drill
Reviewed in the United States on December 2, 2022
Style: Compact Drill/DriverVerified Purchase
This drill has the nice metal chuck and is short. I have lots of Dewalt 20v tools and bought this drill as a gift for a friend because I knew how nice the drill is. I used my identical drill for several days on jobs over the summer where I drilled about 50 holes in wood and steel and it only used 1/3 of the charge on a 2amp hour battery. The variable speed trigger control works smoothly. And the chuck will take a 1/2 inch bit. I have owned several drills over the years and this is the best one.

Reviewed in the United States on April 21, 2020
Style: Compact Drill/DriverVerified Purchase
The first one I received must have been a defective unit, I drilled 3 holes with a very small drill bit into my stainless steel toolbox to mount some handles and it froze up. After trying to free it for a while without resolve I decided to have amazon send a replacement unit. This is one main reason to shop amazon, the replacement came within 2 days, couldn't believe how fast it was here, I boxed up the old one and shipped it back immediately and they let me know when it was received and credited. The new unit has worked flawlessly and I have put it through its paces. with a lot of holes and driving a lot o screws , not issues yet and I don't expect to have any. the drill is solid.

Reviewed in the United States on November 27, 2016
Style: Compact Drill/DriverVerified Purchase
This drill was a replacement drill I purchased after my DCD771 was stolen. This drill does NOT come with a battery, which was fine by me as I had an extra battery already. This is a GREAT drill, going brushless was the best thing I've done, it's considerably more powerful for all applications. I particularly liked how the chuck was metal unlike the plastic ones I've had over recent years, the build quality is stellar. My only gripe with this drill was that it didn't come with a spot to clip a philips / flat head bit on for quick access. It's clearly a tool built for a pro who probably has a tool belt on hand with all the bits he/she needs. I'm just a DIY guy who uses his tools for car, home and community projects. This drill is still considerably lighter than my old 14.4 Dewalt, which now just sits in it's case.

Not the first one I have had. For the size it is deceiving the amount of torque. Hold on to it if it is low gear, it will come out of your hand if the bit stops. Battery lasts for a long time. I use it for home and work.

5.0 out of 5 stars Dewalt é Dewalt
Reviewed in Brazil on October 13, 2022
Style: Compact Drill/DriverVerified Purchase
Eu tenho uma Bosch antigiuinha que já está com a bateria sem segurar carga. Resolvi comprar esta da Dewalt porque já tenho outras ferramentas da marca e conheço a qualidade. E esta parafusadeira/furadeira não é diferente. Ela é muito bruta, tem muita força. Põe minha outra antiga no chinelo. Eu comprei com uma bateria de 5Ah, e uso ela direto. A bateria dura demais, mesmo usando pra furar alvenaria, madeira, parafusar, tudo junto, ela ainda tem carga sobrando. O indicador de carga da bateria é um diferencial, assim como a possibilidade de regular a intensidade do LED. Já trabalhei com ela em lugares mais escuros onde o LED ajudou muito. A única coisa que ela não tem é o impacto, que acho que seria só num modelo superior, porém no resto ela é impecável e me atende 100% nas atividades de reforma de casa.
