The H.15D shares specifications with the H.15 but features a duplex spring for enhanced flexibility. Designed for jewelers, the H.15 Handpiece employs a hammering action at low speeds (0-5,000 rpm) for stone setting and decorative work. It includes an anvil point (HP10177) and requires periodic lubrication.

The hammer provides a 1/32" stroke and adjustable impact (from light to heavy) via the silver knurled adjusting ring. Optional points like 6 different shaped Anvil Points (HP10171, HP10172, HP10173, HP10175, HP10176, HP10179), Pave Point (R15PT), and Stylus with Carbide Tip (HP10212) are available.

Note that duplex springs are not covered by warranty due to potential breakage; they are made of special steel with a protective flexible cover. Replacement springs (HP76) are user-installable. This handpiece is recommended for experienced flex shaft tool users, while most users may prefer the "straight" handpiece (H.15). Dimensions: 9-5/8" long, 1/4" diameter at the tip, weight: 5.2 oz., shipping weight: 7.15 oz. The H.15D hammer handpiece features a duplex spring, enhancing flexibility and delicate control. We advise that only experienced users of flex shaft tools opt for this style of handpiece to fully harness its capabilities.
