Secure, repeatable clamping for round shank bars

A prism insert is designed to transform a conventional holder into a reliable radial clamping system. This insert uses a V-shaped contact geometry to centre and stabilise cylindrical shanks, producing consistent axial alignment and reduced runout. With a clamping diameter of 20 mm and a length of 130 mm, the component offers a balance of engagement depth and compact form, helping to maintain machining accuracy without excessive overhang. The design reduces setup variability and supports efficient changeovers in production environments where consistent part positioning is critical.

Compatibility with interchangeable holders and easy integration

Engineered for use with interchangeable holders, the insert fits into standard prism-equipped change holders and adapts those assemblies for round shank components. The item is sized as Size B, which indicates the dimensional family and ensures predictable fitment in matching holder systems. Installation requires straightforward insertion into the prism pocket of the holder; once located, the insert provides an immediate clamping interface for cylindrical tooling or workpieces. This approach minimises the need for bespoke fixtures and simplifies inventory of clamping elements across different machines.

Practical benefits for workshop and production use

Adopting a prism insert for routine clamping tasks delivers operational advantages: improved repeatability, reduced rework and less time spent on manual alignment. The moderate length confers stability under light to medium loads while keeping the overall assembly compact for confined setups. For operations handling multiple identical shafts or bars, the insert supports rapid, consistent seating that preserves tool life and contributes to predictable cycle times. The component is particularly suited to setups where radial precision matters more than heavy axial loading.

What to consider during selection and use

When selecting a prism insert, confirm the holder compatibility and verify the effective clamping range after installation — here the system provides a maximum clamping Ø of 20 mm for round shank bars once the insert is in place. Size family (B) should match the holder specification to avoid play. Although this insert delivers precise radial support, its suitability for a specific machining task depends on load direction and cutting forces; match the component to the intended application to ensure optimal performance.

FAQ

How does the prism insert improve concentricity compared with plain clamping?
The prism insert centres round shank bars by V-shaped contact surfaces, so the TECWERK prism insert Size B reduces radial runout and provides more consistent concentricity than unsecured seating.

Which holder types accept this prism insert?
The component is intended for interchangeable change holders equipped with a prism pocket; compatibility requires a Size B receptive pocket in the holder for correct seating.

What is the maximum shank diameter that can be clamped with this insert?
After the prism insert is fitted in the holder, the effective maximum clamping diameter is 20 mm for round shank bars.

Is the prism insert suitable for heavy axial loads?
The insert provides stable radial support and moderate axial stability; for heavy axial forces, verification against holder and application constraints is recommended before use.

Can the insert be used for repeatable production indexing?
Yes — the repeatable seating and centring behaviour of the prism insert supports consistent positioning across multiple workpieces in serial production.
