Spotlight
- Reduced nose diameter under the flange to allow compatibility to quick change system
- Taper ground to AT3 or better accuracy standard for maximum contact with spindle
- Runout is less than 0.0002" from taper to end mill pocket
- Made of alloy steel and hardened to HRc 58 and all critical surface is precision ground
- 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
- Each holder comes with a lab certificate on its taper accuracy and runout measurement
- 2 Flats on the nose of the tool holder can be used with an adjustable wrench to assist in tightening the ER collet nut
- 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
