The sharpening angle can be set from 10° to 75° with the WM-200 AngleMaster. The AngleMaster is designed to work on all grinding wheels with a diameter from 150 mm (5 7/8") to 250 mm (9 7/8"). So you get an accurate setting even if you have a grindstone that's been worn down a lot.
The WM-200 AngleMaster has two magnets so you can easily place it on the machine so that it's always close to hand. This applies to all Tormek models except for the 1200 and T-3. On the Tormek T-4, you can place the AngleMaster on the machine plate, which is made of metal; and on the Tormek T-8 you can place it on the plate mount included.
