Summary: I purchased this drill to fasten floor plates to the concrete floor in my basement. It did very well - over 100 holes drilled for the framing job. Cut through concrete very well, if using sharp drills. Goes through cinder block effortlessly.
I love this drill. for the price, it's unbeatable.

Summary: lots of power and easy on the hands. Great for drilling through cement. After 5 minutes of drilling through cement, my hands were not tired and the drill did not excessively heat up. I used a two foot long bit and there was no wobble once I evenly tightened the chock.
Gutless, the gears stripped in the first minute of use

Summary: When I used this for the first time, the gears partially stripped out on the third hole, and now it runs rough. I am going to try to return it. It was for a 1.5" hole in soft waferboard with a flat wood bit.
Summary: I bought because it was on sale for something like $40. After about 10 holes in (hard) concrete, it's locked in hammer mode. No big deal, I have a non-hammer drill too. But if you are looking for something heavy duty, apparently you get what you pay for.
Summary: I tried drilling 2" deep and 3/16" wide holes in a 50+ year old concrete floor with a rotary drill with a concrete drill bit and I spent 10 minutes penetrating thru just 1/8 " of concrete for one hole.
Summary: I purchased this hammer drill from Home Depot and when I attempted to use it the chuck key would not fit properly into the chuck making complete tightening impossiblle. Complete tightening (tightening from all three chuck holes) is important because of the impact nature of the tool which can loosen...
Summary: I purchased this drill because I have a number of other Makita tools and have had good experiences with their construction and durability. Not so with this drill. I used it on two small projects drilling a total of ten 5/32 inch holes and it worked fine.
Summary: Bought drill at HD to install 3/16" tapcons in a concrete slab. After about the 9th hole it suddenly started having bright blue flames appear from the vent slits on the back of the drill. The trigger function started to work intermittently after that until the drill altogether quit.
