Threading chuck DIN 69871 Form A M14–M36 SK50 A‑L 140 mm (TECWERK)

A threading chuck by TECWERK for secure tap holding and versatile use in CNC and toolroom applications

• Steep taper DIN 69871 Form A
• Axial length compensation on push and pull
• Ball guide bushing for controlled movement
• Quick-change insert for torque transfer

Consistent tapping performance for demanding production

The TECWERK threading chuck (SKU 2000832249NW) is engineered for repeatable results when machining threads from M14–M36. Its compliance with DIN 69871 Form A ensures compatibility with standard toolholders and machine spindles, while the SK50 shank provides robust connection to the spindle. The combination of a steep taper and a precisely guided bushing reduces runout and maintains tap alignment, which in turn minimises thread errors and rework. This yields a measurable increase in process stability and shorter cycle variability.

Built-in axial compensation reduces tap breakage and downtime

Featuring axial length compensation on push and pull, the chuck absorbs small axial misalignments that occur during tapping cycles. This function protects taps from excessive bending forces and sudden axial loads, lowering the risk of breakages in interrupted or deep-thread operations. As a result, tool life is extended and maintenance intervals are lengthened, delivering clear economic benefits in high-volume and batch-change settings.

Secure guidance and reliable torque transmission

Guidance is provided by a ball guide bushing, which ensures that the tap runs true and that axial movement remains controlled. Torque is transmitted via a quick-change insert, enabling efficient replacement without special tools and ensuring positive engagement during rotation. Together these features support both hand-tap and machine-tap styles, allowing flexible use across varied tapping tasks while keeping set-up times short.

Practical dimensions and workshop integration

The chuck’s measurable parameters — d 48 mm, A 140 mm, D 78 mm — make it straightforward to verify fitment in existing tool chains. Its execution with a quick-change mechanism simplifies retrofit into modular tooling systems and quickholder arrangements. Where machine uptime and predictable thread quality are priorities, this tap holder supplies a coherent balance of compact form, mechanical security and compatibility with established spindle tapers.

FAQ

Which thread sizes are supported by this chuck?
The threading chuck supports thread taps from M14 to M36 and is specified as suitable for M14–M36 applications.

How is torque transmitted to the tap?
Torque is transmitted via a quick-change insert integrated into the toolholder; the quick-change execution enables secure torque transfer while simplifying insert replacement.

Is the chuck compatible with standard DIN 69871 spindles?
Yes. The chuck conforms to DIN 69871 Form A and is designed for machines accepting that taper, combined with an SK50 shank for robust spindle connection.

What protection against axial load does the holder provide?
The holder incorporates axial length compensation on both push and pull, which reduces stress peaks on the tap and lowers the likelihood of breakage in demanding cycles.

Which guidance mechanism ensures accurate tapping?
A ball guide bushing provides controlled guidance and improved concentricity during tapping, helping to maintain thread accuracy and reduce scrap rates.
