Spotlight

  • Mirror Finish



    To achieve AT3 or better taper contact as an industry standard, our taper surface are precision ground on Shigiya CNC grinder from Japan. We are not satisfied with just meeting the industry standard, the surface roughness on the taper is maintained to mirror finish.

  • Flange and V-groove are precision ground to ensure reliable tool change
  • Spindle Thru coolant capability
