MICRO cut tungsten carbide burs are specifically designed for finishing and are used in areas where mounted points are often used. They offer a higher stock removal rate and produce a high surface quality, particularly when compared to conventional double cut burs. MICRO cut burs also operate with low vibration and little noise, they maintain their geometry over their entire service life, and they work in both manual and machine applications. MICRO cut burs can machine almost all materials up to a hardness of 940 HV (68 HRC). Ball-shaped bur, shape D.
Special features
- High surface quality.
- In comparison to abrasive mounted points, there is no change in geometry due to wear and tear.
- Work on almost all materials up to 940 HV (68 HRC).
- The highly accurate concentricity enables precise work free from chatter marks. This considerably reduces wear on the bur and power tool or machine.
Recommendations for use
- Ideal for finishing, very fine cleaning work, corrections in tool and mold construction, and for sharpening cutting tools.
- Use the burs on powerful power tools with elastically mounted spindles to avoid unwanted vibration.
- Observe the recommended rotational speed.
- For the most cost-effective bur use, work with higher rotational/peripheral speeds. For burs with a 1/4" shank diameter, use power tools with a power output from 300 watts.
