Benefit from conformity with DIN 2185, a fully hardened and ground finish, and a precise MT2-to-MT1 fit that supports reliable tool holding and repeatable setups — order directly via Metav Werkzeuge or consult our specialists for application advice.

Reducing sleeve DIN 2185 MT2→MT1, hardened and ground — TECWERK

A reducing sleeve (DIN 2185) designed to adapt MT2 tooling to an MT1 spindle, fully hardened and ground for precision workshop use.

• DIN 2185 standard compliance
• Hardened and ground inside/outside
• Converts MT2 to MT1 interfaces
• Overall length 92 mm

Precise taper adaptation for consistent machining results

The reducing sleeve delivers a controlled taper transition between a larger and a smaller Morse interface, ensuring accurate concentricity and repeatable positioning. Conforming to DIN 2185, the component is intended for setups where a reliable mechanical fit is essential. By converting an MT2 holder to accept MT1 tooling, the sleeve reduces the need for multiple holders, simplifying tool management and saving setup time in production and repair environments.

Robust, serviceable construction to reduce downtime

Manufactured in the hardened and ground execution, the sleeve offers elevated wear resistance and stable contact surfaces. The internal and external finishing — hardened and ground — helps maintain seating accuracy over repeated insertions and removals, which translates into fewer indexing errors and lower maintenance frequency. For workshops that prioritise uptime, the material treatment and precision grinding contribute directly to longer service intervals and consistent part quality.

Easy integration into workshop workflows and tool holders

Installation is straightforward: the component mates directly with standard Morse taper interfaces, enabling rapid tool changes without special adapters. The 92 mm overall length provides sufficient engagement depth for secure holding while remaining compact for tight spindle envelopes. Because the sleeve follows an established standard, it integrates seamlessly with existing chucks, arbors and tailstocks that accept Morse tapers, supporting flexible utilisation across milling, drilling and reconditioning tasks.

Reliability and traceability through industry standards

Choosing a sleeve produced to DIN 2185 offers clear technical expectations: dimensional accuracy, surface finish and hardness are governed by recognised norms, which supports quality control and documentation in industrial environments. The TECWERK execution emphasises precision finishing and hardened surfaces, which is particularly relevant for operations that expect consistent repeatability across batches and demand confidence in clamping interfaces.

FAQ

What taper sizes does the reducing sleeve convert?

The reducing sleeve converts an MT2 outer taper to an MT1 inner taper; the TECWERK reducing sleeve (SKU 2000832352NW) is specified for this MT2→MT1 adaptation.

Is the sleeve compliant with recognised standards?

Yes, the sleeve is manufactured to DIN 2185, which defines the dimensional and finishing requirements for this type of taper adapter.

How does the hardened and ground finish benefit workshop use?

The hardened and ground surfaces on the TECWERK reducing sleeve improve wear resistance and maintain seating accuracy over repeated use, supporting consistent concentricity and longer service life.

Can this component be used in milling and drilling setups?

The sleeve is suitable for general toolholding applications where a Morse taper adaptation from MT2 to MT1 is required; it integrates with standard chucks and holders that accept Morse tapers.

What is the overall length and why is it relevant?

The overall length is 92 mm, which provides adequate engagement for secure holding while remaining compact enough for typical spindle and arbor arrangements.
