Cut 1 is especially well-suited to machining of non-ferrous metals, steel and cast iron. It is characterized by its high stock removal rate.

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.

Tree-shaped burr with radius end according to DIN 8032 with cut conforming to DIN 8033.

  • 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 prevent vibrations, place the tools on powerful drives with an elastically supported spindle wherever possible.
  • Observe the recommended rotational speeds.
  • If the smallest area of the burr diameter is being used, the recommended rotational speed can be increased accordingly.
  • To ensure cost­effective use of burrs, use a higher rotational speed and cutting speed. Use burrs with a shank diameter of 6 mm with drives with a power output from 300 watts.
