PDT (PDTools) Expert CBN resin bonded stones set

Excellent stones! The first couple of times I had a lot of "loading" issues but it was due to using more pressure than I should have been using. Once I dialed in the amount of pressure I needed to use, and with a little soapy water, they worked flawlessly.

They're good, fast stones. Tiny bit of grit contamination that I didn't expect, but they're pretty good.
