Description

Cut 4 is especially well-suited to machining of stainless steel (INOX), steel and high-temperature-resistant materials such as nickel-based and cobalt-based alloys. It is characterized by its high stock removal rate with short chips and 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.

Pointed tree-shaped burr according to DIN 8032 with cut conforming to DIN 8033, flattened tip.

Advantages
  • 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
  • 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.
