ER 11 Compression Collet Chuck, 12mm Shaft

This is an ER11 style Collet Chuck designed to fit in the Three Gang Blocks at the location where the blocks' are overhanging the Turret. The longer length is short enough to not interfere with the Turret Operation yet allow for adjustment along its axis.

This version comes with compression springs, one guide pin and shaft collar which allows the Chuck to move  along the axis by a small amount (setting the shaft collar closer or further away sets the force and travel).

The unit can also be fixed in place by tightening the sets screws of the Gang Block.

• 12mm Shaft with two flats machined to resist torque on tool and two channels for use as floating holders
• Includes the ER11-A Nut (no collets or other mounting)

Note: Picture with spring installed is that of an ER16 version.
