New digital speed control dial with digital read-out. Exclusive Auto-Cruise button maintains speed even after letting up on foot pedal. This is a high-performance motor. Very smooth and quiet with twist style chuck to quickly exchange out burs and mandrels with ease. Back cord cap removes easily for quick in-office replacement of motor brushes. Compare to our competitor’s units that include only an on/off foot pedal which forces you to adjust the speed at the control box dial. The variable speed foot pedal is a “must have” feature when shopping for a new lab motor! All VECTOR MEGA-Torque Lab Motors come with the variable speed foot pedal option included at no charge!
