Used Open-Box Grobet S300 Flex Shaft Kit-Motor-Plastic Foot Control & No.30 Handpiece-110V

Drive burs, mandrels, brushes, and polishing tools at the bench from one foot-controlled rotary system.

This is a used open-box Grobet S300 Flex Shaft Kit-Motor-Plastic Foot Control & No.30 Handpiece-110V because it was a customer return due to the flex shaft being too wobbly.
