Thread Tapping Chuck (DIN 69871 Form A) – SK40, M5–M22, 97 mm – TECWERK

The Thread Tapping Chuck DIN 69871 Form A is a SK40 toolholder engineered for precision tapping of M5–M22 threads, combining axial compensation with a quick-change system for efficient CNC and toolroom use

• DIN 69871 Form A steep taper
• Axial compensation for push and pull
• Ball-guided bush for precise alignment
• Quick-change insert for torque transfer
• Suitable for M5–M22 thread tapping

Rigidity and repeatable clamping for reliable thread production

The steep taper specified by DIN 69871 Form A and the SK40 mounting deliver high radial and axial rigidity, which is essential for consistent thread quality. By transmitting the torque through a clamped quick-change insert, the system reduces slip and runout so that taps are exposed to controlled forces. This engineering results in higher first-pass acceptance rates and more predictable cycle times, a clear advantage in series production and precision toolrooms.

Built-in axial compensation and guided alignment to protect taps

The integrated axial compensation for push and pull helps to absorb axial discrepancies during tapping cycles, reducing the risk of broken taps in through and blind-hole operations. Coupled with a ball guide bush, the holder guides the tapping tool concentrically, improving thread concentricity and surface finish. These features extend tool life and lower consumable costs by preventing common failure modes during thread cutting.

Fast tool changes and workshop compatibility for smooth workflows

Designed with a quick-change execution and standard dimensions (31 mm shank, 97 mm overall length, 53 mm max diameter), the chuck fits standard SK40 spindles and integrates smoothly into CNC machines and tapping units. Its range, M5–M22, covers a broad spectrum of metric applications, from light assembly threads to medium-duty components. The compact design balances accessibility at the spindle with sufficient clearance for chip evacuation and coolant flow, supporting uninterrupted production.

FAQ

What thread sizes does the chuck support?
The chuck supports metric threads from M5 to M22, as specified for the TECWERK thread tapping chuck (SKU 2000832238NW).

Is the holder compatible with SK40 spindles?
Yes, the holder uses an SK40 mounting and complies with DIN 69871 Form A, making it compatible with standard SK40 tool spindles.

How does axial compensation help tapping operations?
The axial compensation absorbs push and pull movements during tapping cycles, reducing tap breakage and improving thread finish for a more reliable production output.

Can the torque be transferred through a quick-change system?
Torque is transmitted by clamping a quick-change insert, enabling fast tool swaps while maintaining secure torque transfer to the tap.

Which dimensions should be checked before ordering?
Confirm the d: 31 mm, A: 97 mm and D: 53 mm dimensions against spindle clearance and toolholder interface to ensure correct fitment.
