Cut 5 is especially well-suited to fine machining of cast iron, steel, stainless steel (INOX) and high-temperature-resistant materials such as nickel-based and cobalt-based alloys. It achieves a good surface.

Tungsten carbide burrs for general applications are suitable for fine and coarse stock removal on the key materials used in industrial manufacturing. They provide a good stock removal rate and are not specific to a particular material.

Cylindrical burr according to DIN 8032 with circumferential and end cut conforming to DIN 8033.

Tungsten carbide burrs with a long shank are ideal for efficiently machining small, hard-to-reach areas of components. They can be shortened if required. Tungsten carbide burrs with the designation GL 75 mm are made from solid tungsten carbide, which means they can only be shortened using diamond tools.

  • Good stock removal rate through optimum matching of tungsten carbide, geometry, cut and available coating.
  • Long tool life.
  • The highly accurate concentricity enables impact­free working without creating chatter marks. This considerably reduces wear on the tool and tool drive.
  • High surface quality.
Recommendations for use
  • To ensure cost­effective use of burrs, use a higher rotational speed and cutting speed. Use burrs with a shank diameter of 3 mm with drives with a power output of 75 to 300 watts.
Safety notes
  • For safety reasons, the maximum rotational speeds with contact with the workpiece require a reduction in the recommended speed of tungsten carbide burrs with standard shanks. Observe the product information included.
  • When working with long shank lengths, it is crucial that the tool is in contact with the workpiece (or inserted in the bore or slot to be machined) before the drive system is turned on. As a rule, the tool must remain in contact with the workpiece for as long as the machine is running. Failure to observe this procedure may result in burr failure (bending) and hence an increased risk of accidents. If continuous contact between the tool and the workpiece is not guaranteed during use, the maximum idling speeds must not be exceeded.
  • Not suitable for robotic or stationary applications. Risk of bending. Use only rigid clamping systems/drives.
