V-742 Collet chuck (ER-20, Ø34 mm) by Vertex

The V-742 is a collet chuck with a steep taper designed for ER collets, engineered for precise toolholding in milling and machining centres.

• ER-20 taper compatible with ER collets
• Steep taper for reliable seating
• Ø34 mm body, 1.5 kg mass

Consistent precision through secure clamping

The combination of a steep taper and an ER-style interface delivers reliable seating that reduces axial movement during cutting, contributing to repeatable results in production runs. Designed as a compact collet chuck, this toolholder supports tight concentricity when used with quality ER collets; the result is predictable tool performance and less scrap from inaccurate bore or contour work. Where accuracy is essential, the secure mechanical fit is the primary factor in achieving tighter tolerances and improved surface finish.

Easy integration with ER collet systems

Compatibility with the ER-20 standard ensures straightforward integration into common toolholding systems and simplifies inventory management. ER collets provide a wide clamping range while maintaining uniform contact pressure, which makes the holder a versatile component for varied tooling diameters. For workshops converting between operations or retrofitting machines, the compact Ø34 mm body and standard taper mean minimal adaptation is required, shortening setup time and keeping the machining centre productive.

Robust, compact design for daily workshop use

With a mass of 1.5 kg, the holder offers a balance between stiffness and compactness suitable for many milling and machining centre applications. Its narrow profile supports close tool spacing and efficient fixturing in confined work envelopes, helping to reduce interference during multi-tool operations. From repeat production jobs to flexible batch work, the unit contributes to steady cycle times and reliable clamping performance, backed by Vertex’s reputation for industrial toolholding components.
