On my last project I started to get ragged edges around the hole. I tried different ways to drill the hole. Fast and pushing hard and drilling slow all gave the same poor results. I was using a Dewalt battery drill and thought rpm's could be the problem. Also I went and bought a new bit and got the same bad results. I read on the new bit package that the bit needed to be 2300 rpm ( I think)
I went and bought a new corded 2500 RPM 3/8 Dewalt Drill. Problem still there. It first showed up on plywood and I have tested oak, maple, hickory and plywood. Some holes drill fine with a smooth edge hole. But for most cases I still get a splintered edge around the hole. I am using a aluminum jig I bought from Harbor Freights several years ago. I have a Kreg Jig but I like the Harbor Freight one better. Does anyone have any suggestions on how I can improve on drilling the hole?
Thanks
Johnny
