Assembling Collet
ER Collet Insert groove of collet into eccentric ring of the
clamping nut at the mark on the bottom of the nut. Push ER Collet
in the direction of the arrow until it clicks in place. Screw nut
with collet onto toolholder. We recommend tightening the nut with a
torque wrench.
Disassembly ER Collet
After the nut is unscrewed from the toolholder, press on the face
of the ER Collet while simultaneously pushing sideways on the back
of the collet opposite the mark until it disengages from the
clamping nut.

ER collet set is a collection of collets used in machining
and metalworking appliCATEEions. ER stands for "Elastic Retention,"
referring to the collet's ability to grip and hold a tool or
workpiece securely. The collets in an ER collet set are designed
with a tapered shape that allows them to compress and expand to
hold different sizes of tools or workpieces.
ER collet sets typically include a range of collet sizes, such as
ER16, ER20, ER32, or ER40, which correspond to different maximum
tool or workpiece diameters. The set may also include a collet
chuck or holder, which is used to secure the collets in a machine
or tool.
ER collets are commonly used in milling, drilling, and turning
operations, where they provide a precise and secure grip on cutting
tools or workpieces. They are widely used in industries such as
automotive, aerospace, and general manufacturing.
When selecting an ER collet set, it is important to consider the
specific sizes and types of tools or workpieces you will be working
with. Additionally, ensure that the set is compatible with your
machine or tool's collet chuck or holder.
