SB-250
« on: January 03, 2011, 07:46:58 pm »
I have been thinking about getting a Tormek Blackstone Silicon SB-250.  For those of you that have had experience with it, what do you think of it?

Here's a thread on the subject from just a few days ago.

It depends entirely on what you're sharpening. If you're doing planer blades or woodturning tools, I would recommend it. For bench tools, I'd stick with the SG-250.

Interesting.  It did not occur to me to use the SB wheel for lathe tools.  Why not, the modern ones are high speed steel.  I guess the real criteria is the kind of tool steel, not the kind of tool.

Any thoughts on which wheel would work better with A2 steel, as used in some chisels and plane blades?

Hi Ken,

A2 and O1 steels are both HCS tool steels O is quenched in oil and A in air so both would be happier on the original stone.
