Reducing sleeve DIN 2185 MT4 to MT1 — hardened and ground (TECWERK)

A Reducing sleeve DIN 2185 MT4 to MT1 designed to adapt tools with a Morse taper for stable, repeatable mounting in toolholders and arbors

• DIN 2185 standard compliance
• Fully hardened and ground
• MT4 to MT1 taper conversion
• Overall length 124 mm

Precision engineering for reliable taper transfer

The Reducing sleeve DIN 2185 MT4 to MT1 is manufactured to the DIN 2185 standard, delivering a controlled interface between holders and tools with Morse taper shanks. The combination of full hardening and internal/external ground surfaces supports consistent seating and reduces the risk of misalignment during clamping. This results in improved precision during machining set-ups and fewer reworks caused by poor fit.

Durable finish that supports repeatable set-up

A hardened substrate with ground bores and cones provides a robust contact surface that resists deformation under normal clamping loads. The finished surfaces aid concentricity and ensure repeatable positioning across multiple insertions of tooling, which streamlines workshop processes and reduces time spent on re‑alignment. The construction is optimised for routine industrial use where dependable mechanical behaviour is essential.

Compatibility and practical workshop benefits

Designed for converting an external MT4 to an internal MT1 taper, the adapter sleeve suits a variety of toolholders, arbors and fixtures that accept Morse-taper shanks. The 124 mm overall length gives adequate engagement depth for stable mounting, while the adherence to DIN 2185 simplifies specification matching in procurement and maintenance documentation. This adapter supports efficient tool changes and helps maintain organised tool inventories in busy workshops.
