ER11 2 mm collet – reliable clamping for precision micromachining
ER11 2 mm collet is designed to hold tools with straight shanks in the 1-2 mm range. Manufactured from 65Mn spring steel in accordance with DIN 6499B, it allows secure mounting of micro end mills, precision drills, taps, and countersinks in ER11 holder systems.
Key advantages of the ER11 Ø2 mm collet
- Radial runout accuracy ≤0.015 mm — eliminates vibration when machining small parts and extends tool life
- Flexible 1-2 mm range — compensation of 0.5 mm allows clamping of tools with slightly different diameters
- 44-48 HRC hardness of 65Mn material — maintains elastic properties through hundreds of clamping and releasing cycles
- System of 16 flexure slots — distributes clamping force without the risk of deforming delicate tool shanks
- Full compatibility with DIN 6499B / ISO 15488-B — universal fit with ER11 nuts and holders from different manufacturers
ER11 2 mm collet is used for micromachining jewelry components, precision engraving, PCB drilling, and milling miniature components. A solution for workshops and studios requiring the highest accuracy with the smallest tools.
