ER11 COLLET

An ER11 collet is a precision tool-holding device, part of the ER collet system, used in CNC machines, milling machines, and lathes for clamping round-shank tools. It's characterized by its spring action and ability to grip tools tightly, preventing slippage during machining. ER11 collets are smaller and suitable for compact CNC setups and high-precision work. They are designed to accommodate a range of tool shank diameters within a specific range, typically 1mm to 7mm for ER11. 

• Function:

  ER11 collets are used to hold tools like end mills, drills, and other cutting tools in a collet chuck, ensuring accurate tool positioning and preventing slippage. 

  Size and Range:

  ER11 collets are designed for smaller tools and have a clamping range typically from 1mm to 7mm, with each collet having a 0.5mm collapse range

  • Material:

    They are typically made from high-quality spring steel, like 65Mn, which provides the necessary elasticity and clamping force. 

    Standard:

    ER collets, including ER11, are standardized according to DIN 6499,

    • Applications:

      ER11 collets are widely used in CNC machining, engraving, milling, and other applications requiring precise tool holding. 

      • Benefits:

        They offer high precision, good elasticity, and stable performance, contributing to accurate and efficient machining.
