Productive diamond stone on copper-tin M1001 binder for sharpening, refinement, and polishing on Hapstone systems.
Cutting
Diamond abrasive provides fast and efficient sharpening across a wide working range, from rough sharpening to polishing.
Binder
The improved M1001 binder includes nickel and titanium, helping the stones work longer and load less during sharpening.
Ready
Premium series stones are ready to use out of the box, with official factory engraving, passport, and firm blister packaging.
Abrasive grades
Coarse stones use high-strength AC32 diamond powder for active material removal. Fine stones use ACN diamonds for a softer working feel during refinement.
Grain size in JIS may slightly differ between PDT batches, while the micron size remains the exact reference value.
Authenticity
Hapstone is an authorized representative of PDT, so the stones are original PDT products.
