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.

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.

Taper ground to AT3 or better ensures 80% or more contact with spindle to reduce harmonics and improve runout tolerance

Inside bore are precision turned to engage a better contact with retention knob's pilot to increase rigidity

Precision turning surface finish provide perpendicular contact with the flange of retention knob to increase rigidity
