Morse taper sleeve MK4 · 40 mm – TECWERK tool adapter

A Morse taper sleeve designed for the steel holder head C, enabling secure mounting of interchangeable tool holders with a 40 mm outer diameter for efficient workshop workflows

• MK4 shank for standard taper spindles
• Integrated ejector screw for fast tool release
• Compatible with interchangeable holders with cylindrical bore
• Fits steel holder head C

Fast, reliable clamping with repeatable concentricity

The adapter delivers a compact solution for converting an MK4 taper into a receptacle for quick-change tool holders. Thanks to the precise taper geometry and the MK4 configuration, the sleeve ensures secure clamping and a high degree of concentricity between spindle and tool. This reduces run-out and helps maintain cutting accuracy across repetitive cycles, making the component a practical choice where consistent machining quality is required.

Reduced downtime through quick-change capability

Fitted with an ejector screw, the sleeve allows rapid removal of the holder without the need for additional tools, shortening changeover times and improving productivity on the shop floor. The design supports holders with a cylindrical bore, so the adapter serves as a simple but effective interface that minimises handling and streamlines tool management during batch production or mixed-operation setups.

Practical compatibility for common toolholder systems

Engineered for use with the steel holder head C, the taper sleeve covers a typical application range in clamping technology and toolholding systems. Its 40 mm seating dimension provides a standard connection point for many quick-change holders, reducing the need for bespoke adapters and supporting a modular tooling strategy that keeps inventory lean and versatile.

Installation guidance and suitability checks

Although the sleeve is straightforward to fit, correct seating and alignment are essential for optimal performance. The component is intended for holders with a cylindrical bore and a matching 40 mm interface; the ejector screw must be tightened to the recommended torque and checked for free operation. For customers seeking confirmation of fit with specific holders or machines, technical guidance is available to verify compatibility and installation best practice.
