DIN 2187 standard, precision version Fully hardened and ground inside and out For tools with Morse taper MK4 to MK4 265 mm overall length, 48 mm diameter Reliable accuracy for repeatable machining results The extension sleeve is manufactured to DIN 2187, ensuring defined tolerances and a reproducible interface for Morse taper tooling. Its hardened and ground inner and outer surfaces reduce wear and maintain tight contact between tool and adapter, which improves concentricity and minimises radial deviation during machining. For production environments where tooling repeatability matters, the precision finish translates directly into fewer quality checks and less scrap. Straightforward compatibility and secure seating With both inner and outer tapers specified as MK4, the adapter matches standard Morse taper toolholders and accessories, enabling seamless integration into existing setups. The geometric dimensions — 48 mm outside diameter and an overall length of 265 mm with a usable L1 of 147.5 mm — provide predictable extension while preserving rigidity. Because the taper fits are ground to specification, seating is secure and the risk of slippage under load is significantly reduced, which supports consistent cycle times in workshop and light production use. Built for longevity and low maintenance in the workshop The all-hardened construction combined with precision grinding reduces fretting and surface damage, extending service life compared with non-hardened alternatives. The design requires minimal upkeep: regular inspection and light cleaning of the taper seats are usually sufficient to retain accurate seating. Given the material treatment and finish, the adapter offers a long service interval and reliable performance, contributing to stable production processes and lower total cost of ownership over time.

Yes. The Extension sleeve DIN 2187 MK4×MK4 from TECWERK is specified with both inner and outer MK4 tapers and is intended for use with standard Morse taper tooling (SKU 2000832366NW). What benefits does the hardened and ground finish provide? The hardened and ground surfaces on this extension sleeve increase wear resistance, improve seating accuracy and reduce runout compared with untreated adapters, enhancing machining consistency. What are the key dimensions to consider when fitting this sleeve? Key dimensions are an overall length of 265 mm, an outside diameter of 48 mm, and a usable length L1 of 147.5 mm, which determine extension and clearance in the machine setup. Can the sleeve be used for heavy-duty turning and milling? The precision finish and hardened construction improve load capacity compared with non-hardened adapters; suitability for heavy-duty operations should be assessed against specific machine and tooling loads. How often should the taper seats be inspected? Regular visual inspection and light cleaning after routine use are recommended; frequency depends on operating conditions, but inspections before critical runs help maintain accuracy.

300mm Extension Sleeve MK4 to MK5 Hardened Ground, DIN 2187 - TECWERK
Take advantage of a hardened, ground construction and DIN 2187 conformity to maintain spindle accuracy while extending reach; the MT4→MT5 taper pairing and 300 mm overall length deliver reliable tool support and repeatable concentricity in metalworking applications. Order the extension sleeve directly via Metav Werkzeuge or consult the team for application advice. Morse taper extension sleeve MT4×MT5 — TECWERK, hardened and ground, DIN 2187, 300 mm The Morse taper extension sleeve MT4×MT5 provides a hardened, ground sleeve for extending Morse taper tooling, optimised for metalworking and drilling operations where increased reach and maintained accuracy are required DIN 2187 standard compliance Hardened and ground inside and out 300 mm overall length for extended reach 63 mm outer diameter for stable support Maintain machining accuracy over extended reach The hardened and precisely finished inner and outer surfaces are designed to preserve concentricity when a tool is mounted into a smaller spindle via a larger taper. Conformity with DIN 2187 ensures a standardised fit and predictable performance across compatible tooling systems. By combining a controlled MT4 outside taper with an MT5 inside taper, the sleeve reduces radial runout and vibration compared with ad hoc adapters, which helps to secure cutting performance and surface quality in everyday production. Built for industrial stability and repeatability Robust dimensions and surface treatment are the basis for long-term stability: an outer diameter of 63 mm and an overall length of 300 mm provide the mass and support needed for longer overhangs, while the L1 measurement of 182.5 mm defines the usable insertion depth. The fully hardened and ground execution resists wear at contact faces, so the adapter keeps its tolerance profile through repeated tool changes and heavy-duty cycles. This reliability benefits workshops seeking consistent, measurable results from their taper tooling. Simple integration and practical handling in the workshop The sleeve is intended for tools with a Morse taper interface and works as a direct mechanical solution to increase reach without compromising interchangeability; standard compliance allows straightforward replacement and compatibility checks. Install and remove the adapter using standard practice for Morse tapers—ensure clean, dry contact faces and verify seating to achieve optimal concentricity. For complex setups or specific material challenges, technical consultation is available to align the sleeve’s properties with the intended application.
