Foredom® H.15D Handpiece, Duplex Hammer

The Foredom® H.15D Handpiece with Duplex Hammer is a highly specialized, professional-grade bench instrument engineered explicitly for micro-precision stone setting, bezel burnishing, and delicate metal chasing. Standing out from traditional rotary handpieces, the H.15D does not rotate. Instead, this advanced mechanical component converts the rotational force of your flexible shaft system into a precise "reciprocating" stroke, moving the working tip rapidly in and out by exactly 1/32″ to deliver a continuous, high-efficiency hammering action.

By integrating a specialized duplex spring linkage, this model shortens the overall tool profile and introduces an articulation point that allows the frame to bend freely. This design configuration greatly improves the flexibility and maneuverability of the handpiece, making it an excellent match for navigating under high-magnification optics on delicate jewelry contours.

Key Product Features

• Non-Rotary Reciprocating Mechanism: Features a dedicated internal piston drive that strictly delivers a 1/32″ linear in-and-out impact stroke, keeping the tool perfectly stationary against smooth metal faces.

• Integrated Duplex Spring Extension: Incorporates a robust duplex spring assembly that shortens the tool body and provides a flexible bend profile for maximum manual responsiveness.

• Adjustable Striking Force Collar: Built with an integrated silver knurled ring around the handpiece body, allowing the artisan to easily tune the mechanical hammer force to match soft golds or harder platinum alloys.

• Low-Speed Mechanical Engineering: Purpose-built to function at lower operational RPM limits, eliminating friction-related heat generation and maintaining high structural control over the bit.

• Included Fine Anvil Point: Arrives complete with a premium, factory-calibrated fine anvil point tip to enable detailed work right out of the box.

• Broad System Cross-Compatibility: Configured to plug seamlessly into high-performance Foredom Series TX or Series SR pendant flex shaft motors.
