Collet chuck V-742E — ER-20 taper, 34 mm diameter (Vertex)

The Collet chuck V-742E is a steep‑taper collet chuck designed for secure clamping with ER collets, suitable for workshop and production environments where space and repeatability matter

• ER-20 taper compatibility
• Precise clamping performance
• Compact 34 mm diameter

Consistent precision for demanding machining

A steep‑taper collet chuck built for precision reduces variation at the tool tip and supports repeatable setups. The integrated ER‑20 taper ensures compatibility with common ER collets, enabling secure axial and radial clamping. This results in improved clamping accuracy and reduced rework, which directly supports throughput and part quality. Technical terms clarified: ER collets are standard flexible collets that adapt to a range of tool shank sizes, while a steep taper provides a stable mechanical seat that maintains concentricity under load.

Compact form that improves access and workflow

Compact external dimensions minimise interference near the spindle face, making the chuck suited to tighter toolpaths and multi‑tool arrangements. The limited diameter of 34 mm helps to preserve clearance in dense fixturing and machining centres, while the unit mass of 3.5 kg contributes to a stable, vibration‑resistant assembly without excessive overhang. These characteristics help streamline fixturing and reduce cycle‑time losses due to clashes or repeated alignment checks, supporting a more efficient production flow.

Integration and handling for efficient production

Designed for use with standard ER collets, the chuck supports quick tool changes and straightforward maintenance procedures. The steep taper design promotes secure clamping with minimal drawbar adjustment, enhancing repeatability between tool changes. Compatibility with established ER systems makes the chuck easy to incorporate into existing toolholding inventories, reducing the need for bespoke adaptors. Where operators require a balance of accessibility and secure gripping, this collet system provides a pragmatic solution that emphasises operational reliability.
