Taper sleeve DIN 69871 AD MK3, SK40, 70 mm by TECWERK

A Taper Sleeve DIN 69871 AD MK3 for secure clamping in SK40 spindles, designed to accept tools with Morse taper and ejector lugs for efficient tool changes

• Steep taper to DIN 69871 Form AD
• Case-hardened and precision ground
• Accepts tools with Morse taper and ejector lugs
• Compatible with SK40 spindles, length 70 mm

Optimised spindle interface for repeatable accuracy

The adapter is built to the DIN 69871 specification and features a steep taper profile that ensures a tight fit in SK40 tooling spindles. The workpiece-side interface is case‑hardened and precision ground, which reduces wear and keeps axial and radial runout to a minimum. This precision finish translates into predictable machining results and reduces scrap rates in batch production, supporting efficient process control on the shop floor.

Secure acceptance of Morse‑taper tools with rapid ejection

Designed to receive cutters and tools with a Morse taper and fitted for ejector lugs, the sleeve simplifies tool changes while maintaining positive retention under cutting forces. The 70 mm length provides adequate engagement for stability without excessive protrusion, helping to limit vibration and improve surface finish. For applications where tool seating and repeatability are critical, this adapter delivers consistent clamping behaviour that supports higher feed rates and longer tool life.

Durable design that lowers downtime and simplifies inventory

With a surface hardened core and finely ground contact faces, the sleeve offers long service intervals and reliable performance in daily use. The robust construction reduces the need for frequent replacements and, combined with compatibility to common SK40 systems, helps to rationalise tooling inventories across multiple machines. Backed by Metav’s European supply network and quality assurance, the component is positioned as a pragmatic choice for workshops seeking dependable tooling components and steady replenishment.

FAQ

What spindle systems is this sleeve compatible with?
The taper sleeve is compatible with SK40 spindle systems and is designed for use with MK3 mounting as specified in the product data.

Can tools with a Morse taper be fitted into the sleeve?
Yes, the sleeve accepts tools with a Morse taper and is prepared for ejection via standard ejector lugs to enable straightforward tool changes.

How does the case‑hardening benefit daily use?
Case‑hardening on the contact surfaces increases wear resistance and maintains concentricity over longer service intervals, improving component longevity and machining consistency.

Is the sleeve suitable for heavy‑duty milling with higher feed rates?
The combination of steep taper geometry and precision grinding provides improved retention and reduced runout, supporting more stable cutting conditions and allowing higher productive feed rates where machine rigidity permits.

Which standard ensures compatibility and interchangeability?
The component is produced to DIN 69871 Form AD, ensuring compatibility with tooling and spindles that conform to the same standard.
