One thing on the eraser wheel, it works a lot better with a corded drill. Just my .02.
My cordless just didnt cut it. I have the M18 as well. I think the corded has twice the RPM as the M18. 1800 vs 4000 or something like that.Time to retire those 20 year old cordless drills and upgrade lol.
I was in that camp until about 2 years ago and i got a new Milwaukee Fuel M18v brushless hammer drill....dude, that thing just does it, but its kind of heavy so i use my M12 drill for most stuff, but its time to retire it for a new one, had it since 2010 and now it smokes when you put it under load too long.
