ER11 Collet Set (7 pcs) — Precision Tooling for Drill Press and Milling Machines

Upgrade your machining precision with this 7-piece ER11 collet set, designed for drill press and milling machines equipped with an ER11 chuck. Each collet undergoes advanced cryogenic treatment, significantly enhancing its lifespan and ensuring an ultra-smooth inner surface — ideal for high-accuracy work.

The set is engineered with a balanced clamping design, distributing force evenly to prevent runout and machining errors. Manufactured using martensitic heat-treatment technology, it resists deformation and cracking even under demanding conditions.

Crafted from 65Mn spring steel, these collets offer outstanding elasticity, wear resistance, and long-term stability during high-speed operations. Perfect for milling, drilling, boring, and tapping tasks, this ER11 collet set is compatible with most CNC and engraving machines.

👉 Note: To secure the collets properly in your ER11 chuck, a special ER11 nut wrench is required.

Key Benefits:

  • Professional 7-piece (1-7mm) set for ER11 chucks
  • Enhanced precision and extended service life
  • Smooth, uniform clamping with minimal runout
  • Ideal for CNC, milling, and drill press applications

ER11 Collet Installation

  1. Insert the groove of the spring collet into the eccentric ring inside the nut.
  2. Push the collet in the direction of the arrow until you hear a click — this indicates the collet is properly seated in the nut.
  3. Insert the tool (drill bit, end mill, etc.) into the collet. Make sure it is fully seated and straight.
  4. Screw the nut with the collet onto the spindle or chuck body, then tighten it securely using an ER11M wrench.

ER11 Collet Removal

  1. Unscrew the nut with the collet from the spindle or chuck body.
  2. Remove the cutting tool from the collet.
  3. To release the collet from the nut, press the front of the collet inward while gently tilting it at an angle.
  4. Push against the eccentric ring until the collet pops out of the nut.
