Tormek Blackstone Silicon SB-250 is a 250 mm grindstone for sharpening high-speed steel (HSS), such as woodturning tools.
First choose the right grindstone size: 200 mm for the T-4 and 250 mm for the T-8. Then choose by what you sharpen:
Original grindstone SG – an all-round stone supplied with the machine. With the SP-650 stone grader you change the surface from 220 grit to about 1000 grit.
Blackstone Silicon SB – for high-speed steel (HSS), such as turning tools
Japanese water stone SJ – 4000 grit for a polished, razor-sharp edge
Diamond wheel DC, DF or DE – 360, 600 or 1200 grit, for any material including ceramics and carbide. Use the ACC-150 anti-corrosion concentrate in the water.
There are several good ways to sharpen chisels and plane irons: water stones, diamond stones, oil stones and sharpening machines such as Tormek. All give sharp edges, but they differ in speed, maintenance and price.
A honing guide makes it easier to keep the same angle every time. The most important thing is to find a method you enjoy and use often. The guide helps you choose.
