52mm Face Clamping Chuck 20mm Bore, DIN 69871 Form AD, 100mm Shank Length - TECWERK

Take advantage of a compact clamping solution that combines precise axial alignment with a 20 mm clamping diameter and the standardised DIN 69871 Form AD taper for reliable tool holding. Secure integration on SK40 spindles and straightforward specification checks at Metav Werkzeuge ensure minimal downtime and consistent machining results.

TECWERK face clamping chuck – DIN 69871 Form AD, Weldon, 20 mm clamp

A TECWERK face clamping chuck engineered for SK40 spindles to hold cylindrical‑shank tools with a Weldon flat, optimised for general machining applications.

• Weldon clamp with DIN 69871 Form AD taper
• Accepts tools with 20 mm cylindrical shank
• SK40 spindle interface, A 100 mm length

Precise clamping for improved runout and repeatability

The face clamping chuck provides a consistently true running condition thanks to the DIN 69871 Form AD steep taper and the H4 bore tolerance, which together reduce radial and axial play. For shop floors that demand repeatable results, these characteristics mean fewer tool changes due to misalignment and a measurable reduction in scrap. The design secures cylindrical‑shank tools with a lateral drive flat to DIN 1835‑B, maintaining torque transmission while preserving concentricity.

Fast integration with SK40 interfaces and Weldon drive

Compatibility is straightforward: this chuck mates to SK40 taper spindles and accepts tools with a Weldon side flat for positive axial and rotational drive. The compact dimensions – A: 100 mm length and D: 52 mm body diameter – make fitting into existing tool setups uncomplicated, and the 20 mm clamping diameter covers many common cutter shank sizes. Clear reference to the applicable standards simplifies procurement and verification during toolroom planning.

Robust handling and reduced setup time in production

An engineering focus on practical operation keeps changeovers quick and predictable. The Weldon drive provides secure lateral engagement, so clamped cutters resist slippage under cutting loads, while the steep taper ensures firm seating in the spindle. For maintenance planning, the component’s standardised interfaces mean replacement or inspection follows familiar workshop routines without special adapters. Technical queries can be resolved through Metav Werkzeuge’s specialist advisors for precise configuration checks.

FAQ

What tools can be held in this chuck?
The face clamping chuck accepts cylindrical‑shank tools with a lateral drive flat to DIN 1835‑B, specifically for a 20 mm shank clamping diameter.

Is the chuck compatible with SK40 spindles?
Yes, the chuck is designed for an SK40 spindle interface using the DIN 69871 Form AD taper for secure seating.

What does the H4 bore tolerance mean for accuracy?
A bore tolerance of H4 indicates a tight, standardised fit that supports high concentricity and low runout for the clamped tool, enhancing machining precision.

Can this chuck transmit torque reliably under heavy milling?
The Weldon side flat provides positive axial and rotational drive, ensuring secure torque transmission for typical milling and drilling operations.
