I use an older drill doctor that resembles the shape of a tombstone DD700 with two collets (3/32"-1/2" and 1/2"-3/4"). It can sharpen 118, 135 degrees and masonry bits. I really like the split point feature. Have had this for well over a decade and have replaced the diamond wheel once. The diamond wheel can be flipped once prior to replacing it all together.
Fast and easy without the heating up the bit.
Thats the same one I have. I use to sharpen bits by hand with good results, but this baby makes them better than new. There is a "feel" when using this tool, for the guys that don't like em, try it again. If you want to get years of service out of the collets and tool, blow them out often with shop air, keep the abrasive grit from the plastic contact points.Hey everybody ,I got a drill doctor about 29 yrs ago and will never be with out one again there great especially if you don't know how to sharpen drill bits no t for lack of trying,Thought I'd throw in a pitcher of my old drill doctor
