The Tormek Original Grinding Stone has been developed over the years to combine effective grinding with a fine surface finish and long lifespan. The SG-250 is supplied as standard with the Tormek T-8.
The best versatile grinding stone
This grinding stone is the ideal choice if you want both effective grinding and a fine surface finish in the same stone. It works well with various types of tools and steel qualities, including HSS.
Two cutting properties in one stone
Tormek's Original Grinding Stone differs from regular grinding stones in more than one way. The stone's unique composition, together with the SP-650 stone grader, provides you with two cutting properties in a single stone. The stone grader prepares the surface of the grinding stone from its normal 220 grit to provide a surface equivalent to a 1000 grit grinding stone. This is a significant advantage, as you can perform the finishing grind with the same jig settings as during the initial shaping* of the tool.
