TSPROF Alpha 树脂钻石磨石套装，6英寸，SD61 — SD4，240 — 9000目（5件套）

This 5-piece set is incredible. The grit progression from 240 all the way up to 9000 mesh allows you to go from a dull edge to an absolute mirror-polish finish. The resin bond gives excellent tactile feedback compared to traditional metallic bonds. Highly recommend this as a complete premium setup.

Initially I was not expecting much difference compared to the performance of my PDT resin bonded stone, I have the complete line. I will say that there is a noticeable difference in the cut speed as well as the scratch pattern I see. I am very impressed with these, so much so that I filled out the lineup with the rest of the Alpha stone grits and I am awaiting their delivery.
