ER collet is an important element of the equipment of router machines and CNC machining centers. It serves to fix the cutting tool in the spindle unit, and the cutting accuracy depends on its quality and balance. The Stancomplect online store offers for sale ER type collets - the most common of all collet chuck clamps, designed to fix cutters and drills with a cylindrical shank.

Main features of ER collets

ER collets are manufactured in accordance with DIN 6499B standard from 65Mn steel with a hardness of HRC 44-48. Their main feature is the presence of a through hole, which provides a more secure fixation due to the double clamping zone and allows the use of a tool with a shank of any length.

The ER collet chuck is a precision chuck with high accuracy and balance with a runout level of no more than 0.005, 0.008 and 0.015 mm. It can be used for various jobs:

  • drilling;
  • milling;
  • engraving and others.
