When to replace a SG-250 Grindstone based on diameter
On our Woodcraft Guild's T-8, the original grindstone is down to 118 mm diameter (from 250 mm). What is reasonable diameter to go down to that supports investing in a new stone?

Thank you for reaching out with your question.
A diameter of 118 mm on the Tormek T-8 is very small. To ensure maximum compatibility with our different grinding jigs and accessories we recommend to replace the grindstone when it reaches approximately 180 mm (7").
For the Tormek T-4 models the minimum diameter is approximately 150 mm (6").
Good luck and stay sharp!
