ER16 3 mm collet – optimum clamping for small tools with increased rigidity
The ER16 3 mm collet combines the benefits of precision clamping of small diameters of 2-3 mm with the reliability of the ER16 system, which offers greater rigidity than the compact ER11. Made from 65Mn spring steel hardened to 44-48 HRC according to DIN 6499B, it provides a solution for shops requiring stability when working with delicate tools of small diameters.
Advantages of the ER16 3 mm collet in precision applications
- Runout accuracy ≤0.015 mm in accordance with DIN 6499B – ensures surface quality and dimensional accuracy when milling parts with tight tolerances in the IT7-IT8 range
- Clamping range of 2-3 mm with a compensation tolerance of 1 mm – twice the flexibility of ER11 while maintaining the clamping performance required for small diameters
- Hardened 65Mn steel with a hardness of 44-48 HRC – resistance to permanent deformation during repeated tool installation in the production cycle
- System of 16 evenly spaced slots – concentric clamping eliminates localized stresses that could damage thin tool shanks
- Full compliance with DIN 6499B and ISO 15488-B standards – universal compatibility with ER16 holders and nuts available worldwide
The ER16 3 mm collet is ideal for injection mold machining, precision engraving, and the production of optical and electronic parts. Chosen by shops that value a balance between precision at small diameters and the rigidity of a system that provides stability at higher spindle power levels.
Frequently asked questions
This collet holds tools with diameters from 3 to 4 mm, with 0.5 mm compensation capability. Ideally suited to micromachining and precision parts.
Suitable for CNC machines, compact milling machines, and engraving machines for precision work with small tools.
Radial runout does not exceed 0.015 mm according to DIN 6499B. This guarantees stability at high spindle speeds.
The ER11 collet has an outside diameter of 11.5 mm and a height of 18 mm, ER16 has a diameter of 17 mm and a height of 28 mm, and ER32 has a diameter of 33 mm and a height of 40 mm. The collet body always bears the ER11, ER16, or ER32 designation according to DIN 6499B.
