High-performance Resinoid Needle-grinding Wheel B88 Series

B88 series wheels use a bonding material with elasticity and heat resistance optimized for needle-grinding applications.
Deposition on the grain during usage is minimized and stable and superior sharpness is maintained while the amount of burrs generated when grinding needle tips is reduced.


  • The grinding ratio is improved.
  • Grinding burrs are reduced.
