Combination milling arbor DIN 69871 AD/B, SK40, clamping Ø 27 mm — TECWERK

A combination milling arbor designed for secure mounting of milling cutters with longitudinal or transverse key in SK40 spindles, optimised for precise, repeatable machining.

• Steep taper DIN 69871 AD/B for secure seating
• Clamping Ø 27 mm for standard cutter shanks
• Suitable for longitudinal and transverse key cutters
• Induction‑hardened and precision ground for wear resistance

Consistent accuracy through standardised taper and hardened finish

The arbor uses the DIN 69871 Form AD/B interface, providing a steep taper that ensures a positive, repeatable seating in compatible spindles. This standardised connection reduces micro‑movement under load and supports repeatable radial and axial positioning, which is vital for maintaining concentricity during milling cycles. The shaft is induction‑hardened and ground, improving wear resistance and preserving the torque‑transmission fit over extended production runs.

Versatile mounting for keyed milling cutters and robust clamping

Engineered to receive cutters with either a longitudinal key or a transverse key, the arbor enables flexible tooling choices without compromising retention. The clamping Ø 27 mm specification matches common shank dimensions for a wide range of milling tools, and the SK40 interface offers compatibility with many machining centres. By combining these features, the arbor simplifies tool changeovers and reduces setup time, supporting higher machine utilisation and operational efficiency.

Built for workshop reliability and straightforward integration

Manufactured to precise tolerances and finished by grinding, the arbor supports reliable torque transfer and long service intervals, making it suitable for both jobbing shops and production environments. The SK40 shank and adherence to the DIN standard facilitate straightforward integration into existing toolholding systems, while the hardened surface treatment lowers the rate of wear in contact zones. The result is a durable solution that sustains machining accuracy and reduces unplanned downtime.
