DRILL DOCTOR 180 Grit Diamond Replacement Wheel for 350X, XP, 500X and 750X Models - DA31320GF World's Top Grit Wheel

Works great, and leaves a smooth surface (no need to finish with the factory wheel). Great price. easy install. The Drill Doctor is awesome. (Use 135 degree angle for easier drilling in metal).

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.

Easy to replace, with the 180 grits can further refine the drill bits, 100 grits can take down larger drill bits faster.

Nothing to dislike. Good quality and fitted my machine perfectly

Ce modèle de meule est idéal pour rafraichir les forets un peu émoussés. La meule livrée d'origine est beaucoup trop abrasive sauf pour des forets qui sont vraiment usés. Cette meule est indispensable et à prévoir à l'achat de la machine. Je conseille de l'utilisée en opération de finition après passage du grade 100.
