160mm Extension Sleeve MK2 to MK1 Hardened Ground DIN 2187, 20mm Diameter - TECWERK

Take advantage of the combination of DIN 2187 conformity, a fully hardened and ground construction, and a precise MK2→MK1 Morse taper interface for reliable tool holding and repeatable results. Order the extension sleeve directly via Metav Werkzeuge or ask our consultants if needed.

Extension sleeve DIN 2187 MK2→MK1, hardened and ground (TECWERK)

The Extension sleeve DIN 2187 MK2→MK1 is an adaptor sleeve for extending Morse-taper tooling, designed for secure seating of tools with a Morse taper in workshop and industrial settings.

• DIN 2187-compliant accuracy
• Hardened and ground internal and external
• Morse taper interface MK2 to MK1
• Overall length 160 mm, diameter 20 mm

Secure taper interface for consistent tool seating

The sleeve provides a Morse taper MK2 to MK1 connection that secures tools with a Morse taper and reduces runout during machining. By following DIN 2187, the component ensures repeatable taper engagement and positioning, which supports consistent drilling and reaming results. The adaptor is intended for use where a rigid, accurately aligned connection is needed between machine spindle and toolholder.

Durable, fully hardened and precision-ground construction

Manufactured in a hardened and ground finish both internally and externally, the adaptor resists wear from repeated fitting and removal. The full hardening process combined with precision grinding improves contact accuracy and longevity, maintaining a stable seating over extended service life. This construction minimises slop and contributes to stable cutting performance under standard workshop conditions.

Practical dimensions for versatile workshop use

With an outer diameter of 20 mm, an overall length L2: 160 mm and an inner working length L1: 85 mm, the sleeve balances reach with rigidity. These dimensions make it suitable for extending tooling where additional length is required without significant compromise on stability. The compact profile and standard taper interface aid compatibility with typical Morse-taper tooling arrangements used in many shops.

Benefit-driven reliability for production and maintenance

The adaptor’s accuracy execution per DIN 2187 contributes to predictable process behaviour and easier setup times, which supports efficient workshop workflows. The hardened and ground surfaces reduce the frequency of fit-related adjustments and help preserve spindle and tooling surfaces, which in turn lowers maintenance demands and supports uptime.

FAQ

Which tapers does the sleeve adapt?
The TECWERK extension sleeve adapts a Morse taper MK2 to MK1, providing a secure MK2→MK1 taper interface (SKU 2000832315NW).

Is the sleeve suitable for precision tooling?
Yes — the sleeve is manufactured hardened and ground and conforms to DIN 2187, so it is suited to precision operations where consistent taper seating is required.

What are the main dimensions to check for compatibility?
Key dimensions are an overall length 160 mm, a working length 85 mm, and a diameter of 20 mm; verify these to ensure proper fit in the intended setup.

How does the DIN 2187 specification affect performance?
Compliance with DIN 2187 indicates defined accuracy classes and machining tolerances, helping to ensure repeatable engagement and reduced runout for Morse-taper tooling.

Can the sleeve withstand frequent tool changes?
The fully hardened and ground construction is designed to resist wear from repeated fitting and removal, increasing service life under normal workshop use.
