Product features
Mirror Finished
Taper ground to AT3 or better specification ensures 80% or more contact with spindle to reduce harmonics and improve runout tolerance
Pilot Contact
Inside bore are precision turned to engage a better contact with retention knob's pilot to increase rigidity
Taper End Face
Precision turning surface finish provide perpendicular contact with the flange of retention knob to increase rigidity
-
Dynamic Balancing
Tool holder is balanced to G2.5 30,000 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.

Pre-Balance Design
Unique design feature in the flange to minimize the off-balance nature of CAT 40 taper specification. On the shoulder under the flange, a side is mill flat to compensate the weight of the metal chips lost from forming the spherical hole in the flange. This design allows the left side and right side of the holder to achieve 50-50 perfect weight distribution in its upright position, like the position inside a machine spindle. Symmetrical design in evenly weight distribution will minimize centrifugal force in high speed spinning and thus maximize the holder's ability to hold the cutting tool concentric to spindle rotation.
.0002" Runout at 4xD Length
To achieve 3 micron or better internal bore runout, our internal bore are precision ground on Toyo CNC grinder from Japan. There is not cutting corner on this time consuming internal grinding process and the low runout would contribute to longer cutting tool life and better surface finished.
