Flexible Shaft Grinders | McMaster-Carr
Electric Flexible-Shaft Grinders for Bits and Burs. The bendable shaft with handpiece lets these grinders operate smoothly with less vibration, noise, and heat than other hand-held grinders. For proper operation, clean and lubricate shafts every 50 hours of use. 3/4" diameter collet handpiece is well suited for fine, detailed applications.
