156mm Reducer Sleeve MK5 to MK2 Hardened Ground, DIN 2185 - TECWERK

Take advantage of a DIN 2185-compliant taper adapter that combines fully hardened construction and precision ground surfaces for secure tool seating and long service life; order through Metav Werkzeuge for reliable delivery and expert advice.

Reduction sleeve DIN 2185 MK5 to MK2 — hardened and ground, 156 mm length (TECWERK)

The Reduction sleeve DIN 2185 MK5 to MK2 is a taper adapter designed to adapt MK5 holders to MK2 tooling, providing a robust connection for machining and toolholding applications.

• DIN 2185-compliant taper adapter
• Fully hardened steel construction
• Inside and outside precision ground
• Adapts MK5 holders to MK2 tooling

Consistent concentricity through hardened, ground manufacture

The taper adapter is produced to DIN 2185 tolerance standards and is fully hardened, ensuring dimensional stability under repeated loading. The inner and outer surfaces are precision ground, which reduces radial runout and improves tool retention compared with untreated or hand-finished parts. For machining processes where repeatability is essential, the hardened and ground finish maintains seating accuracy over many tool changes and minimises the risk of premature wear or loosening.

Straightforward compatibility and practical workshop benefits

As a taper adapter for Morse taper systems, the component converts an MK5 holder to accept MK2 tooling, simplifying inventory and enabling the use of smaller shank tools in larger spindles. The total length of 156 mm provides a secure engagement depth without excessive overhang, improving rigidity during turning, drilling or reaming tasks. For readers unfamiliar with the term: a Morse taper is a self-locking conical interface used to hold tooling with a matching taper, offering a fast and dependable mechanical fit without additional clamping devices.

Durable performance with low maintenance for industrial use

Constructed for heavy-duty workshop and industrial service, the adapter’s fully hardened body and precision ground faces reduce the frequency of regrinding and replacement, lowering lifecycle costs. The robust design supports high clamping forces and preserves concentricity, which benefits surface finish and tool life. Simple inspection and routine cleaning are sufficient to maintain performance; correct seating on clean mating tapers is the key to consistent results and safe operation in production environments.

FAQ

How does the taper adapter affect runout and concentricity?
The adapter is manufactured to DIN 2185 and, being precision ground, the Reduction sleeve DIN 2185 MK5 to MK2 reduces radial runout and improves concentricity compared with non-ground alternatives.

Can this adapter be used for heavy-duty turning operations?
Yes, the fully hardened construction and 156 mm engagement length mean the adapter is suitable for many heavy-duty workshop operations where secure tool seating is required.

What does MK5 to MK2 compatibility mean in practice?
It means the adapter converts an MK5 spindle or holder to accept MK2-tapered tooling, allowing a workshop to run smaller-diameter tools in larger taper holders without specialised collets.

Is any special maintenance required to keep the adapter accurate?
Routine cleaning and visual inspection are sufficient; ensure mating tapers are free from chips and contamination to maintain the adapter’s performance.
