Foredom H.20D Handpiece, Duplex Quick Change

H.20D has the same specs as the H.20, except includes a duplex spring for added flexibility. H.20D 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.
The collet in this handpiece can be replaced and/or adjusted if the hold on a bur shank is not secure. View the video for instructions on making collet adjustments. 10-1/8" long, 7/8" dia. (center), 3/8" dia. (front taper), wt: 5.4 oz., ship wt. 7.5 oz.
Duplex springs are subject to breakage and are NOT covered by warranty. They are made of special steel, double wound tubular construction with a protective flexible spring cover. Replacement springs (HP76) are available and can be installed by the user. We recommend that only experienced users of flex shaft tools consider purchasing this style handpiece. For most users, the "straight" handpiece (H.20) is the preferred solution.
