This little mighty drill I love it, use it every day, small body with strong engine, not heavy at all, buying another one just as a back up.

It works as it should

    • Shorter means bulkier
Not as slim as its longer counterparts, and doesn’t get into the tighter spaces as well. It still has the power and reliability of Dewalt, and I have found other tasks to use it for in my work- I use multiple impacts to minimize bit changes, and this one has its own specific uses and still works great. ... show more

    • Best impact I’ve used
I do commercial ductwork, and this impact is awesome. It has more torque than any of the other guys impacts, and it fits into tight spots.Im just now reviewing it after almost two years, and I still won’t let them hand me theirs.
