The Tormek Original Grindstone has evolved over the years to offer the best combination of efficient steel removal, smooth surface finish and a long life.
This stone efficiently cuts all types of tools and steel qualities including HSS. It is delivered with the T-8 model (SG-250) and with the T-4 model (SG-200). The unique composition of the stone, together with the Stone Grader SP-650 gives you two different cutting actions in one stone. The Stone grader polishes the surface of the grindstone from its normal 220 grit to a finish that works like a 1000 grit stone. This is a great advantage, since you can do the fine sharpening* with the same setting of the jig as used for the initial shaping* of the tool. The Original Grindstone is the ideal choice when you want both efficient steel removal and fine finish in the same stone over a wide variety of materials, from carbon steel to high speed steel.
