The Foredom H.18D Handpiece with Lever Duplex has the same specs as the Foredom H.18 Handpiece, except includes a duplex spring for added flexibility. For most users, the "straight" handpiece with no duplex spring is the preferable solution.
The H.18 is for use with only 2.35mm (3/32") shank burs. A press lever action is all that is required to change accessories. It features a very slim grip and pre-lubricated ball bearings that do not require any lubrication. 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.
