Standard milling bit with staggered tooth system for universal machining of steel with a hardness < 60 HRC, cast iron, stainless steel, special alloys, hard and tough materials (e.g. Hardox) and hard non-ferrous metals.

Produces short chips and a high surface quality

Manufactured in accordance with strict quality standards including full inspection of soldered connections

Sustainable product packaging made of 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified^®Bronze

Notice

Wear appropriate protective equipment when using the sanding tip, such as eye protection, hearing protection and protective gloves. Please note the recommended rotation speed (n) and cutting speed (Vc) for the material being processed as well as the tool/material assignments in the overview tables. Before using the sanding tip, please ensure that the tip rotates properly and that the clamping function on the tool drive works correctly. Do not choose a clamping length that is too small. We recommend a minimum clamping length of approx. 2/3 of the shaft length. Discolouration may occur on the shaft due to the high cutting performance. This discolouration is caused by the extremely high temperature that the tool reaches and does not pose a safety risk. Materials are generally processed in reverse rotation. Suitable tool drives: flexible shaft drives, straight grinders, robots, machine tools.
