With the innovative STEEL cut, PFERD has developed unique burrs for working with steel and cast steel. They feature tangibly increased aggressiveness and good guidance. They thus ensure safe and precise work. Thanks to their extremely high stock removal rate, burrs with the STEEL cut help users save considerable time when working, thus making them an economically efficient option.

Ball-shaped burr according to DIN 8032.

  • Up to 50 % higher stock removal rate when used on steel and cast steel in comparison to conventional cross-cut burrs.
  • Tangibly more aggressive, large chips and very good chip removal through the innovative tooth geometry.
  • Workpieces are protected through significantly lower thermal load.
  • The highly accurate concentricity enables impact­free working without creating chatter marks. This considerably reduces wear on the tool and tool drive.
Recommendations for use
  • 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.
Safety notes
  • The very high stock removal rate can cause discolouration on the shank. This does not constitute a safety risk.
