Foredom H.15D Hammer Handpiece with Duplex Spring

The Foredom H.15D hammer handpiece is a reciprocating rather than rotary action handpiece. It is used primarily for stone setting but can also be used for texturing, most often with the pave point (diamond tip) accessory, Otto Frei part number 153.195. The diamond tip will produce a bright cut stippled effect. You can also use this handpiece with the Foredom Carbide Tip (HP10212 Otto Frei part number 134.301) for marking or inscribing hardened steel. Threads on these tips are 4-48 US thread, the same as the popular Badeco tips. Use at low speed only (0-5,000 rpm) You must run this device using a Low Speed High Torque Foredom motor item 134.159. This will extend the life of the duplex spring. Remember the pedal controls speed not power.

Requires periodic lubrication with MS10005-Handpiece Lube, Otto Frei part number 134.343.
