H.18D has the same specs as the H.18, except includes a duplex spring for added flexibility. H.18 is for use with only 2.35mm (3/32 Inch) 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. 10-3/8 Inch long, 19/32 Inch dia., wt: 5.3 oz., ship wt. 6.85 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 Inch handpiece (H.18) is the preferable solution.  SKU: FOR-H.18D UPC: 098666715406 BRAND: Foredom MPN: H.18D Made In: United States Check Out The Foredom Tools Catalog Instructions - Foredom Handpiece H.18, H.18D, H.18SJ – Quick Change Micro-Tools makes every attempt to provide accurate information for each item.
