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.
