The H.8D has the same specs as the H.8, except includes a duplex spring for added flexibility. It is a slim collet type handpiece with pre-lubricated ball bearings that require no maintenance. It has a chuck guard that slides back when changing burs. Comes with 3/32″ (installed) and 1/8″ collets and chuck wrenches for changing collets and accessories.
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. We recommend that only experienced users of flex shaft tools consider purchasing this style handpiece. For most users, the “straight” handpiece (H.8) is the preferrable solution.
