- Dynamically balanced to G2.5/25,000 RPM to meet today's demanding need in aggressive high-speed machining
- 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, the ER collet nut is optimized to distribute the flat sides' area to off-set the off-center. ER collet nut is also balanced with each holder
- Made from alloy steel hardened to HRC 52-56
- All critical surfaces are precision ground
- Concentricity is less than 0.0001" from taper to end mill pocket
- Each holder comes with a lab certificate on its taper accuracy and runout measurement
- Coolant through capability
- TIR: 0.00012".
