TECWERK Quick-change holder (for Steel Holder Head B) — 40 mm cylindrical bore, 120 mm length

The TECWERK Quick-change holder (for Steel Holder Head B) is a precision clamping component designed to receive large boring bars and Morse taper sleeves directly for turning and boring operations

• 40 mm cylindrical bore for large shanks
• Direct mounting for big boring bars and MT sleeves
• 120 mm overall length for stable engagement

Faster changeovers with proven repeatability

The quick-change concept reduces machine downtime by enabling fast, repeatable swaps between tools. With a 40 mm cylindrical bore and an overall 120 mm length, the unit provides a consistent seating surface that maintains concentricity and minimises run-out during operations. In practice, this translates into shorter setup times and fewer re-measurements after tool changes, supporting lean production goals and higher machine utilisation.

Designed for heavy boring bars and Morse taper sleeves

Engineered for the direct acceptance of large boring bars and Morse taper sleeves, the holder offers the rigidity required for medium- to heavy-duty turning tasks. The cylindrical reception ensures an even load distribution along the shank, which improves cutting stability and surface finish. For users with mixed tooling—solid bars and MT-mounted tools—this reduces the need for additional adapters and simplifies tooling logistics.

Built compatibility with Steel Holder Head B for straightforward integration

The interchangeable unit is specifically suitable for Steel holder head B, allowing seamless integration into existing quick-change systems that employ this head type. The design eliminates intermediate clamping elements where possible, promoting a compact tool stack and reliable axial positioning. Clear dimensional data—40 mm bore and 120 mm length—supports accurate planning when laying out tool assemblies or verifying spindle clearance.

Supply assurance and quality filter from a trusted partner

Availability is backed by a structured supply chain and a dedicated distribution partner that acts as a European quality filter. Sourcing through this channel provides access to a broad portfolio of precision components and the assurance of consistent product verification. Traceability of the unit and concise technical data help procurement and production planners to align requirements without compromising on operational reliability.
