ER16 2 mm collet – increased compensation for precision tools with small diameters
The ER16 2 mm collet holds tools with diameters of 1-2 mm with an extended compensation tolerance of 1 mm, exceeding the capabilities of the ER11 system. 65Mn spring steel hardened to 44-48 HRC according to DIN 6499B ensures stable clamping of micro end mills, drills, and engraving cutters in CNC machines requiring greater clamping rigidity.
Advantages of the ER16 2 mm collet in precision machining
- Radial runout ≤0.015 mm confirmed by DIN 6499B – maintains workpiece dimensional accuracy at the high spindle speeds typical of small diameters
- Extended 1-2 mm range with 1 mm compensation – twice the flexibility of the ER11 system eliminates the need for additional intermediate collet sizes
- Fatigue-resistant 65Mn steel with a hardness of 44-48 HRC – repeated clamping cycles do not affect the clamping force critical for delicate shanks
- Design with 16 slots ensures concentric clamping – force distribution eliminates the risk of deforming the thin shanks of precision tools
- Manufactured according to DIN 6499B and ISO 15488-B – compatibility with industry-standard ER16 nuts and holders
For small diameters, the ER16 system offers an advantage over ER11 through greater collet mass that reduces vibration and higher clamping rigidity. The collet is suitable for engraving technical parts, machining medical components, and manufacturing electronic components requiring dimensional repeatability.
Frequently asked questions
The ER16 system offers 1 mm compensation instead of the 0.5 mm provided by ER11. Greater collet mass reduces vibration, while higher rigidity improves stability during precision micromachining.
Ideal for micro end mills, jeweler's drills, and engraving cutters with shanks from 1 to 2 mm. Suitable for manufacturing medical and electronic components requiring high repeatability.
65Mn steel hardened to 44-48 HRC and 16 slots that distribute forces guarantee hundreds of cycles without loss of performance. The design does not overstress delicate shanks with small diameters.
