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

Note: Only use concentric chucks Use burrs with long shanks only in holes, do not switch the machine on until the burr is inside the component. v m/min x 1000 D mm x 3.14 Countersinking using the full circumference of the burn speed < 3000 rpm. Stationary use; speed < 3000 rpm acceptable. Materials with poor heat conductivity; reduce speed to avoid overheating of the burr. Maximum cutting speed: 900 m/min.
