ER11 x 115mm Straight Shank ER Collet Holder - Mini Nut

ER11 Straight shank ER collet holder - 115mm gauge length with Mini locknut. Featuring through hole for internal coolant & stop screw. Straight shank ER collet chucks enable the user to reap the benefits of the exceptionally precise method of clamping offered by ER collets, the world's most popular tool holding system; in applications not limited to spindle tooling systems. Straight Shank ER Collet Chucks are particularly useful for extending the reach of a lathe or milling machine. They feature a non-tapered shank for use with certain straight shank machinery.

Straight Shank ER Collet Chucks mount to the working side of a lathe spindle in the same way as a three-jaw chuck. ER Collet Chucks of this type use the machine’s existing hydraulic cylinder and drawtube for actuation. The installation of an ER Collet Chuck usually requires the fitment of an intermediate adapter between the drawtube and chuck to compensate for position and thread disparities.
