Collet chuck V-749 – SK‑40 toolholder with ER‑25 compatibility by Vertex

The Collet chuck V-749 is a steep‑taper toolholder designed for secure clamping of ER‑25 collets in metalworking and precision machining applications

• SK‑40 taper for rigid toolholding
• Compatible with ER‑25 collets
• 42 mm outer diameter, compact design

Maximise rigidity for consistent results

A steep SK‑40 taper produces a concentrated contact area between spindle and toolholder, which increases axial and radial stiffness. The resulting reduction in deflection and chatter leads to more precise cuts and improved surface finish. For workshops where repeatability matters, this design decreases the frequency of rework and extends cutting‑tool life by maintaining a stable tool position under load.

Versatile clamping with standard ER‑25 collets

Compatibility with ER‑25 collets offers broad tooling flexibility while keeping changeover straightforward. The chuck accepts standard ER‑25 collet inserts, enabling a single toolholder to cover a range of shank diameters with repeatable concentricity. This simplifies inventory management and reduces set‑up time, supporting efficient workflows in both jobbing shops and production cells.

Compact form and predictable handling for workshop use

With a 42 mm outer diameter and a mass of 1.1 kg, the toolholder balances compactness with substantial mass for vibration damping. The Vertex design focuses on a robust connection to SK‑40 spindles, delivering dependable clamping without unnecessary bulk. Where machine clearance and accessibility are restricted, the smaller envelope of this chuck aids fixturing and toolpath planning without compromising stability.

Built for reliability and straightforward service

Manufactured under Vertex quality standards, the chuck is intended for routine industrial use with simple maintenance routines. Regular cleaning of contact faces and lubrication of threaded elements preserve concentricity and service life. Clear identification by SKU and GTIN supports traceability and spare‑parts matching for effective workshop logistics.
