What is proper setting of tool rest clearance for bench grinder?

The proper setting of tool rest clearance for a bench grinder is typically around 1/16 inch (1.5 mm) from the grinding wheel. This small gap allows for effective grinding while minimizing the risk of the tool touching the wheel, which could cause damage or kickback. Adjust the tool rest to ensure it is securely locked in place, maintaining stability and safety during use. Regularly check the clearance as the wheel wears down to maintain optimal performance.
