Collet ER32-GB — clamping Ø 9 mm with 7 mm internal square (TECWERK)

The Collet ER32-GB is an ER-design collet with an internal 7 mm square, engineered for thread-cutting applications and compatible with ER collet chucks and thread-cutting collet holders.

• Compatible with ER collet chucks
• Internal square 7 mm for thread cutting
• Runout accuracy 15 µm

Accurate thread-cutting with industrial-grade concentricity

The ER-GB design provides runout accuracy 15 µm, which minimises radial play and supports consistently accurate thread cutting and tapping operations. The combination of a clamping Ø 9 mm and a compact length 40 mm results in a compact toolholder that reduces vibration and wear on cutting tools. This level of precision translates into fewer rejected parts, longer tool life and a more predictable production process for workshop and light industrial environments.

Efficient compatibility to streamline workshop workflows

Designed according to DIN 6499, the collet integrates seamlessly with standard ER chucks and thread-cutting collet holders, enabling quick changeovers and stable torque transmission via the 7 mm internal square. The square drive permits engagement with taps or driving squares during machining, which means less auxiliary tooling and fewer setup steps. Such compatibility reduces machine downtime and harmonises with established clamping systems in small to medium-scale production.

Robust specification and quality orientation from TECWERK

The ER-GB collet is specified for a clamping diameter of 9 mm and a length of 40 mm, features that support stable clamping for common metric tooling. Conformity with DIN standards and the clearly stated runout accuracy 15 µm provide measurable assurance of performance rather than subjective claims. The design focus is on repeatability and reliable torque transfer, attributes that contribute directly to process stability and higher first-pass yield in thread-related machining tasks.
