Screwdriver Handle with Extension, RA-Hex Connection with Shock Absorption, for Screwing and Hammering | Helmut Zepf No. 47.502.10
The Screwdriver Handle with Extension from Helmut Zepf GmbH (item no. 47.502.10) is the RA-Hex driver for the Pi-Series osteotome inserts. Its shock-absorbing coupling lets the same handle be used for both screwing and hammering: screw-osteotome inserts (47.937.05, .10, .11) are advanced by rotation, while osteotome inserts (47.937.12–.14) can be tapped with a mallet. The extension gives reach in the posterior maxilla.
Backed by our Helmut Zepf Warranty — this instrument is warranted against defects in materials and workmanship for 1 year. Full terms and how to make a claim are on the Warranty page.
