The #20 is for exclusive use with 3/32" (2.35mm) shank burs. A lever action on the the handpiece body is all that is required to change accessories. It has a molded plastic front grip with tapered sides for easy and close handling, plus pre-lubricated ball bearings that do not require additional lubrication.

Handpiece #20 measures 5-5/8" long x 1-1/8" diameter at the center tapering to 3/8" diameter at the front. Weighs 4 oz.

With the addition of a Duplex spring, #20D is more flexible than the standard model. Used for very delicate work and when more precise control is needed. Recommended for experienced flex shaft users.
