TECWERK Weldon face clamping holder — SK40, 8 mm clamping Ø, 100 mm length

A Weldon face clamping holder in DIN 69871 Form AD for secure mounting of cylindrical-shank tools with a lateral drive surface to DIN 1835-B, designed for use in SK40-equipped milling spindles

• Weldon lateral drive for secure tool transmission
• Compatible with DIN 69871 Form AD (SK40)
• 8 mm clamping diameter for cylindrical shanks
• 100 mm overall length for deeper reach

Precision clamping for consistent machining results

The TECWERK Weldon face clamping holder combines a steep taper and lateral drive to ensure dependable torque transfer and low runout. The DIN 69871 taper in Form AD provides a well-established interface for mounting in SK40 spindles, while the Weldon flat secures tools with a side drive feature. This arrangement reduces vibration and improves repeatability during high-precision milling and finishing operations, translating technical reliability into predictable production output.

Built for accurate alignment and practical reach

Manufactured to tight tolerances, the holder features a bore tolerance H4 that supports concentricity and stable clamping of cylindrical shanks. With an overall length of 100 mm and an outer diameter of 28 mm, the design balances accessibility and rigidity for tools that require extra reach without compromising stability. The clearly defined 8 mm clamping diameter simplifies tool selection and helps reduce changeover time through consistent seating and clamping behaviour.

Straightforward compatibility with standard tooling systems

This clamping arbor accepts tools with a cylindrical shank and lateral drive surface to DIN 1835-B, making it suitable for widely used tool geometries in workshop and industrial milling environments. Compatibility with SK40 interfaces ensures easy integration into existing machines, while the Weldon drive provides a positive, slip-resistant connection. The result is a component that supports efficient setup, reliable tool retention and the confidence to maintain steady production rhythms.
