Machine suitability:
The HF L Z7 tungsten carbide burr can be used with straight grinders, flexible shaft drive machines and air grinders. The recommended cutting speed is 450–600 m/min for unalloyed steels/cast steels/cast iron, and 250–350 m/min for alloyed steels/tool steels/rust- and acid-proofed steels.
Structure and production:
The head is attached using a specialised brazing technique, while the teeth are cut using high-precision diamond discs on advanced CNC machines. This technique ensures an optimum and high-performance cutting geometry.
Applications:
This carbide burr as a double cut variant with chip breaker offers users a long tool life as well as high concentricity at a low price.
Dimensions:
The carbide burr with shape L (ball-nosed cone) according to DIN 8032 is available with a head diameter of 12.7 mm. The shank diameter is 6 mm.
