DA31320GF 180 Grit Diamond Replacement Wheel for 350X, XP, 500X and 750X

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.

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.

ドリルドクターを使い始めて数年、研ぎ具合が甘くなってきた為交換。 もっと早く替えれば良かったが値段が高いので躊躇した。

ottimo prodotto

These work good
