ER16 High-Precision Spring Collet | DIN6499B Industrial Grade Chuck
The TriQuench ER16 High-Precision Spring Collet is a cornerstone component for high-performance CNC machining where runout precision is vital. Specifically optimized for stone carving and high-speed routing, these collets are forged from premium 65Mn spring steel and hardened to HRC44-48 to provide maximum clamping force without sacrificing elasticity. Strictly adhering to the DIN6499B industrial standard, each collet is precision-ground to maintain a sub-micron T.I.R. (Total Indicated Runout), effectively extending tool life and ensuring a superior surface finish on the workpiece. The advanced double-slit architecture ensures a secure, uniform grip across the entire tool shank, making it ideal for the high-vibration environments typical of stone and composite machining. Whether integrated into an HSK spindle or a standard ER tool holder, our ER16 collets deliver the repeatable precision required for high-end industrial fabrication.
- Ultra-low runout (T.I.R.) for vibration-free high-speed operation
- Forged from high-grade 65Mn steel for maximum tensile strength
- Surface hardened to HRC44-48 for superior wear resistance
- Full compliance with DIN6499B international quality standards
- Specialized double-slit design for uniform clamping and concentricity
- Fully ground surfaces for 100% contact between spindle and tool shank
- Optimized for high-frequency spindles up to 30,000 RPM

Technical FAQ & Operational Guide
How does an ER16 collet differ from ER25?
The ER16 series is smaller, designed for tool shanks up to 10mm, whereas ER25 supports up to 16mm. ER16 is preferred for high-speed, light-duty applications like engraving and stone carving due to its lower mass and higher RPM capability.
What happens if I use a tool that is slightly outside the clamping range?
Using a tool outside the specified 0.5mm - 1.0mm collapse range of the collet can lead to poor concentricity, increased runout, and potentially permanent deformation of the collet spring.
Why is 65Mn steel used for these collets?
65Mn is a high-carbon spring steel that offers excellent elasticity combined with high yield strength, ensuring the collet returns to its original shape after every tool change.
