Concentricity/runout less than: 0.0001 / 0.003mm. Collet Chuck accepts all ER25. Works on all CAT 40 machines.

Certification included with each holder, documented TIR, taper accuracy and balance measurement. Tools are manufactured by an. Dynamically balanced to 20,000RPM at G2.5 by Haimer balancing machine at all location for consistent balance. 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. Presetter and balancing Design, in a generic standard ER collet nut, an internal ring is off-centered so that an ER collet can be easily snapped into it and holds the ER collet in place.

To minimize this off-centering, SHARS ER collet nut is optimized to distribute the flat sides' area to off-set the off-center. Made of Superior Alloy Steel, body and nut select Forging Parts, high precision and long life. Taper ground = AT3 or better accuracy standard for maximum contact with spindle. All critical surface are precision ground. Concentricity is less than 0.0001 from taper O.

Each holder comes with a lab certificate on its taper accuracy and runout measurement on its taper accuracy and runout measurement. Internal set screw is included and can be used as a stopping pin to prevent end mill or drill from sliding backwards while performing heavy cutting. Coolant through capability by removing the internal set screw. The inner holes will be inspected on product line one hundred percent by USA air jet instrument.
