Poltava Premium Metallic CBN Stones 1x6

Highlights Metallic CBN Sharpening Stones from Poltava Diamond Tools are designed for guided knife sharpeners (Hapstone, TSPROF, and other Edge Pro-compatible systems). CBN (Cubic Boron Nitride) is the second-hardest material after diamond, providing high endurance and low wearing rate with copper-tin alloy bonding. Description The Premium series of Metallic CBN Stones features a 3 mm thick CBN-bearing metal plate mounted on a high-quality aluminum blank. The CBN grain is made in the USA. CBN offers exceptional hardness, strength, abrasion resistance, thermal, and chemical resistance, surpassing synthetic diamonds and conventional abrasives like silicon carbide and aluminum oxide. Due to its high thermal stability and chemical resistance, CBN is suitable for sharpening in conditions where synthetic diamonds are not typically used. CBN stones can be used without lubricants, making them the cleanest option among available sharpening stones.
