H.20D has lever action on the the handpiece body to change accessories. It has a molded plastic front grip with tapered sides for easy and close handling, pre-lubricated ball bearings that do not require additional lubrication and includes a duplex spring for added flexibility. Only for use with 3/32″ (2.35mm) shank burs.
The collet in this handpiece can be replaced and/or adjusted if the hold on a bur shank is not secure.
10-1/8″ long, 7/8″ dia. (center), 3/8″ dia. (front taper), 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.
H.20D is a standard key tip handpiece.
