Extension

With drive spindle extensions, shanks of grinding and milling tools can be extended. They allow access to difficult-to-reach areas and are clamped into the collet of the machine (air or electric grinder) or into the flexible shaft handpiece. Drive spindle extensions are a cost-effective alternative to special made-to-order burrs and mounted points with long shanks. Extension for drive spindles with a working length of approx. 50 mm, a tool mounting of 3 mm and a shank holder of 6 mm. Recommended extension for drives with a maximum rotational speed of 44,000 RPM. 1 key EM SW 13/64", 1 key EM SW 9/32" and 1 collet 3 mm.
