- Simple, durable, and reliable structure
Built on the classic draw‑in collet design, this system delivers stable clamping force over long‑term use, making it one of the most trusted workholding solutions on the shop floor.
- High repeatability for mass production
Precision‑ground tapers ensure excellent repeatability and consistent clamping, improving machining quality and dimensional stability in high‑volume CNC operations.
- Fast changeover to boost productivity
No adjustment or calibration is required. Collets can be swapped by simply threading them in or out, significantly reducing machine downtime.
- Easy operation with no technical skill required
The system is operator‑friendly and does not rely on skilled technicians, helping reduce labor costs and increase production flexibility.
- International standard sizes with global compatibility
5C, 16C, YB15, and YB25 are widely recognized collet system standards, compatible across multiple brands and machines for effortless maintenance and procurement.
- Versatile configurations for flexible applications
Available in pointed, extended, double‑layer, square, hexagonal, and other custom designs to support turning, fixturing, secondary operations, and a wide range of precision workholding needs.
