Combination milling arbor DIN 69871 Form AD/B – SK40, clamping Ø 32 mm (TECWERK)

The Combination milling arbor DIN 69871 Form AD/B, designed for SK40 spindles, secures milling cutters with longitudinal or transverse slots and supports precision machining in workshop and production environments.

• Steep taper DIN 69871 Form AD/B
• Clamping Ø 32 mm for slot-type cutters
• Case-hardened and precision-ground
• Compatible with SK40 spindles

Secure, standardised holding for precision milling

The combination arbor is built to the DIN 69871 specification, delivering a steep taper interface that ensures repeatable seating and minimal runout when used with compatible toolholders. Its design is aimed at stable torque transmission for slot-mounted milling cutters, so concentricity and tool life are improved compared with non-standard adaptors. The clamping diameter 32 mm provides a firm mechanical engagement for cutters with either longitudinal or transverse slots, making the arbor a dependable choice for tasks that demand dimensional accuracy and consistent surface finish. Clear mechanical fit reduces rework and enhances process reliability.

Robust surface treatment for extended service life

Manufactured case-hardened and ground, the arbor benefits from a hardened working surface that resists wear under repetitive clamping cycles and abrasive machining conditions. The hardened layer increases the component's service life while the ground finish guarantees a precise seating surface, supporting stable axial and radial positioning. With a projection of A = 60 mm and a working length L = 24 mm, the geometry supplies sufficient reach for many cutter types without excessive overhang, reducing vibration and the resulting tool wear. This combination of surface treatment and dimensional control helps lower maintenance intervals and limits unplanned downtime.

Versatile compatibility for workshop and CNC operations

Conformity to DIN 69871 Form AD/B and the SK40 connection make this arbor suitable for a broad range of milling machines, from manual mills to CNC machining centres that accept the SK40 interface. The external diameter of 58 mm and the standardised taper ensure interchangeability between machines and toolholders, simplifying tool management and spares provisioning. The arbor accepts cutters with longitudinal or transverse keyways, enabling flexibility across milling applications and allowing workshops to standardise on a single holder type for multiple cutter families. The result is faster set-up times and smoother production workflows.

FAQ

What does DIN 69871 Form AD/B indicate for this arbor?
DIN 69871 Form AD/B denotes a standardised steep taper interface; the combination milling arbor is manufactured to this norm to guarantee correct seating and interchangeability with SK40 toolholders and spindles.

Which cutter types can be fitted to the arbor?
The TECWERK combination milling arbor accepts milling cutters that have either a longitudinal or a transverse slot; the clamping diameter 32 mm secures cutters designed for slot clamping.

How does the case-hardening benefit workshop use?
Case-hardening increases surface wear resistance on the arbor, so the seating surface and clamping zones retain dimensional stability over many cycles, which prolongs service life and lowers maintenance needs.

Is the arbor suitable for CNC machining centres with SK40 spindles?
Yes, the arbor is compatible with SK40 spindles and is intended for both CNC machining centres and manual mills that accept the DIN 69871 Form AD/B taper.
