Carbide Rotary Burr SM Shape


Cemented Carbide rotary burrs are specially designed for very hard processing materials, which can be used for deburring, chamfering, trimming, sharpening and cutting holes. Divided into single cutting and double cutting, we provide a variety of models to deal with various applications. SM shape is pointed cone, it can be used to process hard-to-reach places. Because it is clamped on a high-speed rotating tool for manual control, the pressure and feed rate of  cemented carbide are determined by the service life and cutting effect of tool.
