59mm Thread Tapping Holder M3–M14 SK40 With Quick-Change, Axial Compensation DIN 69871 Form A - TECWERK

Take advantage of the combination of secure SK40 seating, length compensation under load and a quick-change insert for reliable torque transmission to maintain consistent tapping quality and minimise downtime. Order the thread tapping chuck directly via Metav Werkzeuge or ask the consultants if further specification support is required.

Thread tapping chuck DIN 69871 Form A M3–M14 SK40 L 59 mm — TECWERK

The Thread tapping chuck DIN 69871 Form A M3–M14 SK40 L 59 mm is a quick-change tapping chuck designed for precise internal thread production on machines equipped with an SK40 spindle interface.

• Steep taper to DIN 69871 Form A
• Length compensation under compression and tension
• Ball-guided bushing for precise alignment
• Quick-change insert for torque transmission
• Suitable for taps M3–M14 in SK40 holder

Secure seating and repeatable concentricity for reliable tapping

The DIN 69871 compliance and SK40 interface ensure a secure mechanical connection between spindle and toolholder, delivering consistent concentricity for tapping operations. The steep taper provides a firm fit that reduces vibration and runout, which in turn supports improved thread form and surface finish. Where machine stability and repeatability matter, this holder offers a measurable increase in process reliability without requiring complex setup changes.

Stable thread formation through axial compensation and guided support

Integrated length compensation for both compression and tension protects the tap and the workpiece during thread cutting, accommodating axial deviations encountered in interrupted or deep-hole tapping. The ball-guided bushing ensures axial alignment while the quick-change insert transmits torque cleanly to the tap, reducing the risk of breakage and improving tool life. These features together promote uniform thread geometry across batches and lower reject rates in serial production.

Efficient integration and compact dimensions for workshop workflows

Compact dimensions — projection A: 59 mm, diameter D: 36 mm, pilot d: 19 mm — allow straightforward integration into existing tool cycles and reduce the risk of collisions in tight tool arrangements. The design supports fast tooling changes and short set-up times, contributing to higher machine uptime and more efficient shop-floor throughput. The combination of robust mechanical design and quick-change capability is particularly suitable for small and medium series where flexibility and reproducibility are priorities.
