Face clamping chuck DIN 69871 AD/B, Weldon 16 mm, SK40 – TECWERK

A face clamping chuck that secures cylindrical-shank tools with a Weldon flat, designed for SK40 toolholders and equipped with central coolant and resealable channels for industrial milling and machining applications.

• SK40 taper for standard milling spindles
• Weldon 16 mm clamping for secure retention
• Central coolant supply with resealable channels
• Bore tolerance H4 for consistent concentricity

Precision clamping for reproducible machining results

The holder delivers consistent concentricity through a bore manufactured to H4 tolerance, reducing run-out and improving surface finish. Designed to the DIN 69871 toolholder standard, the unit ensures repeatable alignment in machining spindles with SK40 taper, which supports stable cutting conditions and predictable cycle times. The Weldon clamping interface secures tools with a lateral drive flat, preventing axial slip under heavy cutting loads and contributing to process reliability in batch production.

Integrated coolant system to extend tool life

A central feature is the central coolant supply combined with resealable coolant channels at the flange and lateral coolant passages. This arrangement provides direct coolant delivery to the cutting zone for tools with cylindrical shanks and a lateral drive flat as specified by DIN 1835-B, improving chip evacuation and reducing thermal load. The targeted coolant flow lowers wear rates, which translates into longer tool life and fewer interruptions for tool changes — a tangible efficiency gain for production environments.

Dimensional compatibility and robust design for workshop use

Key dimensions such as the clamping Ø 16 mm, projection A 63 mm and outer D 48 mm are matched to common tooling requirements, ensuring compatibility with standard shank diameters and fixture geometries. The construction supports industrial use, providing a compact footprint and predictable mechanical behaviour under cyclic loading. The holder’s design balances stiffness and accessibility, so set-up and replacement are straightforward while maintaining the mechanical integrity required for repeated spindle insertions.

Why this holder benefits industrial workflows

By combining a standardised SK40 taper, secure Weldon clamping, and an industry-oriented coolant concept, the chuck reduces process variability and supports higher machine uptime. For procurement and shop-floor planning, the solution reduces the need for multiple ad hoc holder types and simplifies inventory control. Its specification-driven design makes it suitable for a broad range of milling operations where concentricity, coolant management and secure tool retention are decisive for quality and productivity.

FAQ

What diameter of tool shank does the holder accept?
The clamping diameter is 16 mm; the chuck secures cylindrical shanks with a Weldon flat for positive drive.

Is the holder compatible with SK40 spindles?
Yes, the face clamping chuck is designed for SK40 taper toolholders in accordance with DIN 69871 AD/B.

How does the coolant system work on this chuck?
Central coolant is supplied through the shank with resealable channels at the flange and lateral channels for tools with a cylindrical shank and lateral drive flat, improving coolant delivery to the cutting zone.

What tolerance should be expected for the bore?
The bore is manufactured to H4 tolerance, ensuring consistent concentricity and minimising run-out.

Which standard defines the lateral drive flat compatibility?
Lateral drive flat compatibility follows DIN 1835-B, enabling secure torque transmission for tools with a Weldon-style flat.
