Nice little drill

Nice little drill
Good hammer drill. Bought this after a brand new craftsman hammer drill died out on the 2nd day of use. This Dewalt got the job done anchoring posts to brick for a patio railing and is still running strong.

Reviewed in Canada on July 6, 2020
I never thought I will consider "made in Mexico" will be a better choice than "made in China" . Nominal 8.5 A power. 51000BPM , very easy control of the drill speed. Recommended. It looks like American producer controls much easier Mexican manufacturer than the Asian ones. Quality is evident, design is outstanding. Spend a little bit more and you save a lot for the next years.
