TECWERK Weldon Face Clamping Chuck (DIN 69871 Form AD), SK40, 6 mm

A TECWERK Weldon face clamping chuck (DIN 69871 Form AD) designed for SK40 spindles, optimised to hold cylindrical‑shank tools with lateral drive according to DIN 1835‑B for machining tasks requiring repeatable clamping accuracy.

• Weldon shank retention for secure lateral drive
• Compatible with SK40 taper to DIN 69871 Form AD
• 6 mm clamping bore, H4 tolerance for accuracy

Precision clamping for consistent machining results

The Weldon retention method, paired with the DIN 69871 Form AD steep taper, provides a compact interface that reduces axial play and improves repeatability. The clamping bore of 6 mm with H4 tolerance ensures consistent fitment of tooling shanks and supports stable rotational behaviour under load. These characteristics translate into measurable improvements in machining consistency and reduced rework rates when compared with non‑standard holders.

Seamless integration with standard toolholders and tools

Designed for tools with cylindrical shanks and a lateral drive to DIN 1835‑B, the face clamping chuck offers straightforward compatibility with common tool inventories. The SK40 spindle interface allows rapid fitting to matching machine tapers, while the specified projection A: 100 mm and body diameter D: 25 mm keep the tool envelope compact for improved accessibility in tight setups. Together, these features simplify tool change planning and support efficient spindle use.

Workshop robustness and straightforward handling

Built to fit standard shop practices, the holder supports frequent tool changes without elaborate procedures, reducing fixture downtime. The simple Weldon flat engagement provides positive axial and rotational transmission for small‑diameter cutters, and the adherence to DIN tolerances facilitates predictable maintenance cycles. For workshops aiming to standardise clamping equipment, this chuck delivers dependable behaviour that aligns with established machining workflows.

FAQ

What shank sizes are supported by this chuck?
The TECWERK Weldon face clamping chuck is specified with a 6 mm clamping bore (H4), making it suitable for cutters with a 6 mm cylindrical shank and a Weldon flat.

Is the chuck compatible with SK40 spindles?
Yes. The holder uses the SK40 spindle taper to DIN 69871 Form AD, allowing direct mounting to SK40 toolholders that conform to the same standard.

What does the H4 bore tolerance mean for workshop use?
An H4 tolerance indicates a precise bore fit that minimises play between the tool shank and the clamping bore, improving repeatability and reducing runout for the tool assembly.

Can the chuck be used with tools that follow DIN 1835‑B?
Yes. The clamping chuck is designed to accept cylindrical‑shank tools with lateral drive according to DIN 1835‑B, ensuring positive torque transmission via the Weldon flat.

How does the Weldon retention affect tool change speed?
The Weldon flat offers a straightforward mechanical engagement that supports quick manual or mechanised tool changes while maintaining secure axial and rotational engagement for small‑diameter tools.
