i&Gaiaiit Luk s HOLEX Burrs Version Applications Burrs of high-performance carbide grades with high toughness and excellent cutting edge stability. The shank is made of steel if the head 0 is larger than the shank 0, otherwise it is of carbide. HSS burrs are optimised for difficult vibration applications. For both manual and robot-mounted use for deburring, edge breaking, cleaning, and dressing weld seams and surfaces.

Stationary use; speed < 3000 rpm possible. Materials with poor heat conductivity; reduce speed to avoid overheating of the burr. Maximum cutting speed 900 m/min. Types of cut and applications good Machinability difficult Type of cut selection Note Only use concentric chucks Use burrs with long shanks only in holes. Do not start the machine until the burr is inside the component. 1024 Main catalogue Hoffmann Group 46
