Review: Much Better Than My Bosch 18V - Much Better Than My Bosch 18V I switched from an 18V Bosch hammer drill to this DEWALT 20V MAX, and the difference is substantial. Build quality feels a clear step up—I’ve dropped this one from a ladder several times with zero damage. Power delivery is stronger and more consistent thanks to the brushless motor, while the compact size handles tight spots well. It fits perfectly into my existing DEWALT battery system. The only downside is some fatigue during long overhead sessions due to weight. Solid, durable tool that outperforms my old Bosch in everyday use.
Review: Used but new? - I am sure the drill is great. Much heavier and torque than my one of over 19 years that I love. I needed the upgrade for the hammer drill for framing a couple of medium size rooms into concrete. What annoyed me, I got it for Xmas from the family (I chose it) but it came with no box or manual. Do I really need these things, no, probably not. It does suggest that this was a returned item. Also fine, it appears unused, no blemishes at all, but I paid for a new unit. Might return it, just to make sure I get what I paid for. Really hate when desertcart tries to pawn off returned items as new, without the proper packaging.

## Questions & Answers

**Q: Will the worklight turn on when the trigger is pulled if the light switch is at the off position? the manual says yes, but mine doesn't.**
A: Yes and no ... there are three settings: 1) always on 2) always off and 3) on only when the trigger is pulled (plus ~10s delay turning off when trigger released).

**Q: Is this hammer drill compatible with the DCB201 battery?**
A: Thank you for your question. It is compatible with the DCB201 battery. All DeWalt 20 volt Max batteries and chargers are interchangable with all DeWalt 20 volt max tools. We would suggest if you will be doing a longer project, you may want to consider upgrading to a 3 (DCB203) 4 (DCB204) or 5 (DCB205) AH for less charging time in-between work but the 201 has worked great for the small-medium projects I've done. It also charges fairly quickly (about 30-45 minutes in DCB107). Another added benefit of the DCB201 is that it's a lighter weight battery which doesn't add as much weight to the drill. Great question!

**Q: what is the power of this drill?**
A: Thank you for your question. Here are some specs regarding the power of the DCD805b. High-speed transmission with variable trigger and 2 speed settings (0-650/0-2,000 rpm). Maximum Speed is 2000 RPM. Max torque is 796 in-lbs. Blows per Minute is34000 BPM. Hope these stats help you make your purchasing decision. Great question!

**Q: What type of drill bit will fit this to drill through concrete ?**
A: The DEWALT SDS+ Hammer Bit, Rock Carbide, 1/2-Inch by 16-Inch by 18-Inch (DW5440) would work for this application.
