Product Spotlight

  • Dynamic Balancing



    Tool holder is balanced to G2.5 20,000 RPM on a HAIMER Tool Dynamic Balancing System from Germany.  Balanced tool holder minimizes the centrifugal forces which minimize the stress on spindle bearing, minimize vibration and maximize the cutting tool's life cycle and greatly improve surface finish. 

  • Micron Tolerance



    By utilizing the state of the art Okamoto ID CNC grinder to precision grind the internal bore, the runout tolerance is very stable in batch production. Runout is carefully inspected to ensure within 3 micron (0.0001") from taper to ER collet pocket.

  • 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.

  • High Torque Collet Nut



    The maximum torque is laser marked on the ER collet nut face to take the guess game out of the way to ensure proper amount of force should be applied while tightening. 8 Degree SK collet seats deeper in the pocket than 16 degree taper ER collet, providing twice more clamping force and twice more accuracy during high speed machining. Collet edge seats flush with the front surface of collet nut to maintain strong rigidity.

  • 5 Micron Runout


    Each collet is inspected 3 times at 0, 120, and 240 degree at 4 times diameter to guarantee the 5 micron (0.000197") runout tolerance.  This inspection process is also repeated 3 times with fully disassemble collet from the collet nut and the tool holder to guarantee consistent runout tolerance
