Customer Questions & Answers

this is a drill "kit" does it come with drill bits?

Asked by: Anonymous
No dill bits provided. Does have a good quality blow molded case that is easy to use and has space inside to store bits. Some cases today once the tool is removed you have trouble getting them back in. That is not the case with this one.

does this drill use an sds bit

Asked by: Anonymous
No it does not use sds bits. Wanted it to be able to punch holes with hole saws so purchased it with a chuck. We drill holes for remodeling baths and kitchens up to 6" and I like our work to look professional, and not hacked up.

8.5 Amp 1/2 in. Corded 2-Speed Hammer Drill Kit is rated 4.0 out of 5 by 6.
Rated 5 out of 5 by from Excellent Hammer Drill Bought mine a few months ago and noticed that it must be an updated version because it's 9.2 Amps..............a real little powerhouse! With good quality, sharp bits, it will go into masonry & concrete at a very reasonable rate short of using a rotary hammer drill for more demanding jobs. One reviewer said that his depth gauge wouldn't hold, but if it's put in correctly with the teeth facing the right way in the slot, it works just fine. Great little brute-of-a tool...............as expected from Bosch.

Rated 5 out of 5 by from Built like a Battleship! Purchased for drilling into a 1950's brick & concrete porch which was badly "pitted" on it's top. Drilled 24 3/16" holes into the concrete top / sides to take 1/4" Tapcon anchors for the 2x6 sleepers we installed. Other than for changeing out the drill bit frequently so-as-to keep a sharp bit in action, we had no trouble what-so-ever. the HD21-2 drilled into the concrete "like going into butter". Friends & Family laughed at the fact that my wife & I were "still talking to each other" at the end of the project. I figure this hammer drill will last me the rest of my life with no need of replacement.

Rated 1 out of 5 by from Failed in less than an hour I purchased this drill based on reviews. With less than 1 hour of use, it appears that the gears stripped. I could hold the chuck with my hand, apply power, and the chuck would not move
Date published: 2015-04-25
Rated 4 out of 5 by from Tool has good weight and torqe unlike some models used We have used the drill twice now and it seems to be the one we have been looking for. The chuck uses a key so you can lock the drill or hole saw in and have it stay. Our experience with other name brand manufactures drills have been less than desirable.

Rated 4 out of 5 by from Would have been 5 stars Read the other positive reviews to see what to like. The depth gauge is the only poor feature... it consistently slipped with just the slightest pressure and was useless.
