Tormek SB-250 Blackstone Silicon Stone

Tormek SB-250 Blackstone Silicon Stone

With the new generation of edge tools becoming harder and containing alloys which make them tough to grind.

The Tormek Blackstone silicon SB-250 is designed for hard materials and fast sharpening. It delivers fast steel removal on HSS and exotic alloys and can 'touch up' tungsten carbide. The key to removing material efficiently at low rpm is very sharp grains with high hardness and relatively fine grit size. The SB-250 is made in the same grit size as the original Tormek grindstone and can be graded with the stone grader for fast material removal or fine surface finish.

The combination of grit hardness, shape and size makes the SB-250 Blackstone Silicon work efficiently at the low rpm speeds of the Tormek machine. The higher abrasiveness of the stone is especially valuable when shaping tools with a large bevel or sharpening surface where the grinding pressure is low, such as planer blades and woodturning chisels.
