We are not satisfied with just meeting the industry standard, the surface roughness on the taper is maintained to mirror finish.Tool holder is balanced to G2.5 20,000 RPM on a 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.
