Tungsten carbide burrs with the MICRO cut are specifically designed for finishing and are used in areas in which mounted grinding points are used for example. They offer a higher stock removal rate and produce a high surface quality, particularly compared with conventionally milled surfaces. They also operate with low vibration and little noise. They maintain their geometry over their entire tool life, and are well-suited to manual and machine applications. Almost all materials up to a hardness of 68 HRC can be machined.

Cylindrical burr according to DIN 8032.

  • High surface quality.
  • Unlike with mounted grinding points, there is no change in geometry due to wear and tear.
  • Use on almost all materials up to 68 HRC.
  • The highly accurate concentricity enables impact­free working without creating chatter marks. This considerably reduces wear on the tool and tool drive.
Recommendations for use
  • Particularly well suited to finishing, for very fine cleaning work, corrections in tool and mould construction or for sharpening cutting tools.
  • To prevent vibrations, place the tools on powerful drives with an elastically supported spindle wherever possible.
  • Observe the recommended rotational speeds.
  • 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.
