The machine was purchased for use in drilling and Fräsständer. The surface in the area of 43mm clamp is painted and not rotated, but sufficiently long to ensure with 24mm length for secure clamping. Processing Machine is very good, as is the engine running and the use of quick-action chuck. The integrated LED lights up from helpful. Long-term experience, however, are just as little as before the use as a hammer drill in concrete etc.
