Secure tool clamping that reduces runout and saves setup time

The ER collet chuck design combines a standardised ER25 interface with a steep taper per DIN 69871 Form AD, providing a compact yet rigid connection between spindle and tool. The ER system accommodates a wide range of cylindrical shank diameters, notably 2–16 mm, which reduces the need for multiple holders and minimises changeover time. The result is improved repeatability and a measurable reduction in tool runout, giving consistent surface finish and longer cutter life.

Easy integration and reliable holding force for diverse shop tasks

The steep SK40 taper and standardised mounting allow the tool holder to be fitted quickly to compatible machine spindles, delivering a secure clamping force for light to medium machining. With a 100 mm projection and D 42 mm body diameter the unit balances accessibility and rigidity, enabling work on deeper features without excessive overhang. The interface is designed for collets to DIN 6499, ensuring simple collet changes and broad compatibility with commonly used cylindrical‑shank tools.

Built for workshop efficiency and predictable performance

Engineered for routine production and maintenance shop use, this collet chuck offers predictable performance across repeated cycles. The standard conformity (DIN 69871) and ER system mean spare collets and accessories are widely available, reducing downtime. For procurement teams seeking dependable tooling that simplifies inventory, the holder represents a practical compromise between flexibility and precision, backed by a known industrial standard.
