Face clamping chuck DIN 69871 Form AD, Weldon, 32 mm – TECWERK

A face clamping chuck engineered for secure mounting of tools with cylindrical shanks and a side drive flat to DIN 1835‑B, intended for use in SK40 spindle systems and precision machining applications

• DIN 69871 Form AD compatible
• Weldon flat for positive drive
• 32 mm clamping diameter H4 bore
• SK40 taper, 65 mm projection

Consistent tool retention for repeatable results

The chuck is designed with a Weldon side drive flat to ensure secure torque transfer between spindle and toolholder, reducing slippage under load. Manufactured to DIN 69871 Form AD with a tight H4 bore tolerance, the unit provides a repeatable fit that minimises axial play and helps maintain concentricity throughout the production run. This stability supports consistent cycle times and reduces the need for frequent re‑setting, which benefits batch machining and high‑precision operations alike.

Clear compatibility with SK40 spindles and cylindrical shanks

Built to accept tools with a cylindrical shank and a lateral drive flat in accordance with DIN 1835‑B, the chuck matches common workshop tooling standards and fits SK40 tapers. The compact design, with a 65 mm projection and 50 mm body diameter, allows installation in a wide range of vertical and horizontal machining centres where space and clearance are critical. Stating mechanical compatibility in measurable terms enables straightforward integration into existing tool repertoires without guesswork.

Precision clamping diameter for accurate centring

The central feature is the 32 mm clamping diameter, produced to H4 tolerance to guarantee tight centring of the tool shank. Accurate centring reduces runout and supports improved surface finish and prolonged tool life by keeping cutting forces predictable. The combination of standardised dimensions and tight tolerances provides a verifiable basis for process planning and quality control, making the chuck suitable for tasks that demand repeatability rather than bespoke fixturing.

Practical benefits for workshop efficiency

By following established standards and providing a robust mechanical connection, the component simplifies procurement and tool management. The use of recognised standards reduces the need for specialist adapters and streamlines inventory. Where fast tool changes and dependable retention are priorities, the chuck acts as a straightforward mechanical solution that favours operational continuity and lowers the risk of unscheduled downtime when fitted correctly.
