Description

Tungsten carbide copy milling burrs by PFERD are the perfect tools for levelling elevations, such as weld seams. Thanks to the uncut area, the weld seam can be adjusted to the level of the surrounding surface without this being damaged. Copy milling burrs are used in particular in the repair of cutting and punching blades in tool and mould-making.

Tungsten carbide copy milling burrs with cut 4 are designed for coarse stock removal.

Inverted cone-shaped rotary cutter, tapered towards the shank. Inverted cones WKN are especially well-suited to processing punching tools that are used for processing aluminium.

Advantages
  • Long tool life and high surface quality.
  • The uncut area provides optimum contour guidance and protects the workpiece against damage.
  • Reduced machining time.
Recommendations for use
  • For accurate contour guidance, copy milling burrs can be used with guide aids.
  • 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.
