TECWERK Morse taper sleeve – MK4 adapter with 50 mm bore and ejection screw

The Morse taper sleeve is an MK4 taper adapter designed for steel holder head C and for use with changeable holders featuring a cylindrical bore.

• Adapter for MK4 shank, secure fit
• 50 mm diameter for cylindrical bores
• Integrated ejection screw for easy removal
• Compatible with steel holder head C

Faster changeovers through precise taper adaptation

The sleeve offers a clean mechanical solution for integrating modular changeable holders with existing toolholding systems. By adapting the MK4 taper to a cylindrical changeable-holder bore of 50 mm, the component reduces fixture modifications and shortens downtime. The hardened taper geometry ensures repeatable centring and precision seating, which translates into consistent run-out and improved part quality. This makes the adapter a rational choice where reliable alignment and swift tool swaps determine productivity.

Secure retention and straightforward removal for workshop routines

Retention is assisted by an integrated ejection screw, which enables controlled release without damaging the holder or fixture. The screw mechanism simplifies disassembly, lowering maintenance time and reducing the risk of seizing under heavy use. Where fixture accessibility is limited, the sleeve’s design supports dependable locking while permitting efficient removal—helping to avoid costly rework and to keep operations on schedule.

Built for robust use in industrial environments

Constructed for compatibility with steel holder head C and standard changeable holders, the adapter is intended for frequent handling and repetitive tool changes common in production workshops. The tailored interface to cylindrical bores protects mating surfaces and distributes contact forces to reduce wear. As a result, the sleeve contributes to longer service intervals for tooling assemblies and a lower total cost of ownership, while maintaining the mechanical integrity required for demanding machining tasks.
