Drill DoctorDA31320GF 180 Grit Diamond Replacement Wheel for 350X, XP, 500X and 750X

I assume this is same as the one that came with their 350 model. That one is still in use and doing well. It is 180 grit also according to the documentation.

Quality was very good

I have had good luck with these cutting wheels as well as the Drill Doctor machines they are made for. I have used both the 500X machines and the 750X machines. If you pay attention to the instructions they will do a professional job of sharpening regular high speed type bits, split point HS bits, and masonry bits. For years I got by with drilling holes with some very unprofessionally sharpened bits, but it sure works better to have them sharpened right. Of the affordable drill bit sharpeners I have seen I like Drill Doctor the best.

The drill doctor products always works well sharpening drill bits

Will work fine when needed

I have not had to yet replace the grinding wheel, but I would expect the replacement to work just as well as the original that came with the Drill Doctor.
