Questions & Answers
Are DeWalt cordless drill and cordless palm sander batteries interchangeable?
Yes, The DEWALT 20V MAX tools are compatible with all DEWALT 20V MAX batteries.
How do you put in a drill bit
To insert a drill bit or other accessory, follow these steps. 1. Turn tool off and disconnect tool from power source. 2. Grasp the black sleeve of the chuck with one hand and use the other hand to secure the tool. Rotate the sleeve counterclockwise (as viewed from the front) far enough to accept the desired accessory. 3. Insert the accessory about 3/4" (19 mm) into the chuck and tighten securely by rotating the chuck sleeve clockwise with one hand while holding the tool with the other hand. Continue to rotate the chuck sleeve until several ratchet clicks are heard to ensure full gripping power. Be sure to tighten chuck with one hand on the chuck sleeve and one hand holding the tool for maximum tightness.
Will this handle drilling through 8" of concrete?
No
No this does not have a hammer option. If you're doing 8 inches of concrete get a SDS hammer drill. This drill is very powerful and would help in a lot of situations but not this one.
Yes
This Model is not designed for drilling concrete. This model doesn't feature a hammer drill function for drilling concrete. Wood, Steel, Plastics, Composites but not Concrete. There is another Model that appears identical to this unit that offers a Hammerdrill feature.
With this type of hammer drill you may have to start with a small bit and work your way up to the desired size. The brushless drill stops whenever it binds. That’s one thing I don’t like about it.
Does this have enough power to operate a hole saw in wood?
Oh, yes. It has plenty of power!
It does to an extent but there’s a better tool for it. An angel drill would be a better choice.
Way more than that - it runs my 10" ice auger in sub zero temps, with the ice being 4 feet thick with no problem. It drills more than 20 10" ice holes on one 20v charge, probably more than that but I never had a need for more and still had charge. Great tool.
Does this drill work for drilling into brick?
Hello DrillingBrick Thank you for your contact. We apologize for any trouble or inconvenience in finding information. This drill can be used for drilling into brick. For masonry, such as brick, cement, cinder block, etc., use carbide-tipped bits rated for percussion drilling. However, if the drill's primary purpose will be drilling into brick and masonry, we would recommend getting a hammer drill such as model number DCD996. Best Regards Sherri C DEWALT
Yes
Has anyone used this drill with an ice auger?
Yes, I use this with my K-drill and it works great. I have a 6amp hour battery that will drill about 20 holes through 14" of ice.
No
How much torque does this tool have?
it has enough torque
95 Nm max torque, which is 840.8 in-lbs. In independent tests it's been found that this is an underrated number, it is likely closer to 1000 in-lbs. Milwaukee rates their best drill at 1200 in-lbs, but that number seems to be overrated. Honestly they are both about the same.
The DCD991B has 820 UWO. We no longer use torque to rate the power of our drills. We now use unit watts out or UWO. UWO is the maximum power output for a drill system. It takes into account the efficiency of the entire drill system (transmission, clutch, and chuck). UWO measures the power of the drill at the chuck.
Difference between DCD791 and this one DCD991?
2 speed vs. 3 speed transmission as well as 11 vs.15 clutch settings. DCD991B specs note all metal transmission... DCD791B - https://www.dewalt.com/products/power-tools/drills/drills-and-hammer-drills/20v-max-xr-liion-brushless-compact-drilldriver-tool-only/dcd791b DCD991B - https://www.dewalt.com/products/power-tools/drills/drills-and-hammer-drills/20v-max-cordless-brushless-xr-3speed-drill--driver-kit/dcd991b
The dcd991 has three speed setting and is a bit larger than the dcd791.
