MO4020 = Marathon N7R High Torque Micromotor

MARATHON N7R MICROMOTOR with STANDARD HANDPIECE
Micromotors are small, fast power tools ideal for polishing, drilling, grinding plus many other bench jobs. The micormotor consists of 2 parts: the base unit and the handpiece.  The base unit controls the speed and direction by delivering electrical power to the handpiece.  The handpiece does the work.  It houses the tiny motor right inside thus the name micromotor.

Use all of your favorite standard Flexshaft abrasives and attachments! The handpiece features a quick change collet that holds 3/32" (2.38mm) shanks. This means you can still use all your standard bits and polishers. 

And with the quick change collet, it's a breeze to switch polishing bits.  Just a twist of the handpiece releases the bit and a twist back locks it in place.  No fumbling with chuck keys or collet wrenches.  So no wasted time or headaches!
