Spotlight
- Balanced to 20000 PRM at G2.5
- 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 from alloy steel harden to 54-60 HRc
- Taper ground to AT3 or better accuracy standard for maximum contact with spindle.
- All critical surface are precision ground
- Concentricity is less than 0.0002" from taper to end mill pocket
- Each holder comes with a lab certificate 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
