H.20D has the same specification and features as the H.20, except it includes a duplex spring for added flexibility. H.20D is made to be used exclusively with 3/32" (2.35mm) shank burs. Quick Change handpieces are great for quickly changing bur without having to use a key. A lever action of this handpiece is similar to the well know Italian Faro Handpiece or Swiss Technique Handpiece and can be open or closed with one hand using the side mounted lever 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.

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
