TECWERK ER25 Collet Chuck – Clamping Range 1–16 mm, 20 mm Shank

The TECWERK ER25 collet chuck for secure clamping of tools with cylindrical shanks in ER collets, suitable for workshop and light industrial toolholding applications.

• ER 25 collet system compatibility
• Clamping range 1–16 mm
• Cylindrical shank with lateral clamping face
• 42 mm body diameter for stable mounting

Consistent clamping for efficient production

The ER collet chuck is engineered to provide repeatable clamping when changing tools frequently. With a clamping range of 1–16 mm and compatibility with the ER25 interface, the holder reduces downtime and supports predictable machining cycles. The cylindrical shank and lateral clamping surface contribute to axial stability, while adherence to DIN 6499 ensures compatibility with standard collets. This results in improved process reliability and fewer interruptions in daily workshop operations.

Easy integration and practical handling on the shop floor

Designed as a compact, straightforward toolholder, this collet chuck fits into existing setups without complex adaptations. The 20 mm shank suits common machine spindles and fixtures, and the 42 mm body diameter provides a steady seating in the spindle or arbor. Clear mechanical design lowers the learning curve for operators and simplifies routine tool changes, which helps to raise throughput and keeps handling consistent across different operators and shifts.

Durable design meets standardised tooling requirements

Built with a focus on mechanical integrity, the chuck’s geometry supports secure clamping of cylindrical-shank tools and long-term stability under load. Compatibility with standard ER collets to DIN 6499 makes the system flexible for a wide range of cutters and reamers. The robust body and lateral clamping face contribute to vibration dampening and consistent concentricity, which assists in maintaining surface finish and dimensional accuracy during repeated machining tasks.
