Review on DEWALT DW5245 4 Inch 12 Inch Carbide: Ultimate Cutting Performance for Precision Projects by Dave Mosby

This hammer was just the right tool for my car lift project (a Triumph NT9 9000lb lift was also purchased from Revain!). I first used this drill on normal drill settings and it got through the first inch in about 90 seconds once I put the drill in percussion mode - wow! It worked exactly as intended - each 4" hole was light, smooth and fast! And with six drill bits for each post I completed this part of the project quickly, the drill bit did a great job removing debris from the hole too and the carbide tip doesn't even look worn! I could probably clean it up and pass it off as new, but it'll stay in my toolbox for another day (not sure what, but we'll see what project I can think of next). If you drill holes in concrete check out this Dewalt drill bit, five stars for sure!
