Description

Oval bur.

Advantages
  • High-quality HICOAT coating for high hardness and wear resistance.
  • Good stock removal rate due to high quality tungsten carbide, bur shape, cut, and optional coating.
  • Durable.
  • The highly accurate concentricity enables precise work free from chatter marks. This considerably reduces wear on the bur and power tool or machine.
