Okay, maybe not a HOT knife, but compared to the one I've used it drilled through blocks quickly and with less pressure. MAYBE I was trying to squeeze too much life out of what I had, but since changing that, my frustration factor has dropped significantly. Not only is it less time per hole, but I'm pressing so gently now that I'm not pressing on the lining as I pass. Maybe a bit of Makita will make a difference with my Makita Bulldog (that's what YOU would say anyway), but overall I'm very happy I made this purchase. I've got about eight holes so far and I'm expecting a few more. eighty,,, more?We'll see.
