SHARS NMTB40 ER 40 SPRING COLLET CHUCK SET. 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.

Each holder comes with a lab certificate on its taper accuracy and runout measurement. 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. 1pc of NMTB40 ER40 Collet Chuck.
