Collet chuck V-746 — steep-taper toolholding for ER collets by Vertex

The collet chuck V-746 is a steep-taper, ER-compatible toolholding solution designed for precision machining and secure clamping in compact spindle environments

• Steep ER-40 taper for secure clamping
• Compact 63 mm diameter for tight spindles
• Low runout for consistent machining
• Balanced 1.6 kg body for reduced spindle load

Secure clamping for consistent machining results

A steep taper combined with ER collet compatibility delivers secure clamping and improved concentricity, which directly reduces vibration and tool deflection. The taper design locks the collet into the chuck with high axial and radial stability; this mechanical principle translates into lower runout, longer tool life and more predictable part quality. For production environments where repeatability matters, the emphasis on precise seating and stable axial preload supports shorter set-up intervals and fewer reworks, contributing to higher throughput and process reliability.

Compact design that preserves spindle dynamics

With a compact 63 mm diameter and a balanced mass of 1.6 kg, the chuck minimises overhang and helps maintain spindle balance during high-speed rotation. The reduced frontal footprint is especially useful in machining centres with limited clearance or in fixtures where space optimisation is critical. By keeping inertial load low, the design helps to protect bearings and contributes to consistent surface finish quality, while the modest weight supports faster acceleration and deceleration cycles without compromising stability.

Straightforward integration and dependable compatibility

Designed for standard ER collets, this chuck streamlines tool changes and inventory management by using widely available collet sizes and accessories. The steep taper geometry promotes secure seating even under cyclic loading, making it suitable for repetitive milling and drilling tasks that demand repeatable clamping force. The Vertex engineering focus ensures compatibility with common spindle interfaces and a robust mechanical connection that supports everyday workshop demands. For operators with varying tool sets, the combination of standard collet use and a compact chuck body simplifies tooling logistics and reduces the number of specialised holders required.

FAQ

What collets are compatible with this chuck?
The V-746 collet chuck is compatible with standard ER collets; the steep ER-40 taper is matched to ER collet sizes designed for that series.

How does the taper affect runout and tool life?
A steep, well-machined taper improves axial seating and radial support, reducing runout and therefore decreasing tool wear while enhancing part accuracy when using this Vertex collet chuck.

Is the chuck suitable for high-speed applications?
The compact 63 mm footprint and balanced mass of 1.6 kg support stable spindle behaviour; suitability for specific spindle speeds should be confirmed against machine specifications.

Can the chuck be used with existing ER tooling?
Yes — the V-746 is designed for integration with common ER tooling, enabling simpler tool changeovers and inventory standardisation.

What are the benefits of choosing this Vertex chuck for production?
The combination of a steep ER taper, compact design and balanced construction provides reliable clamping, repeatable accuracy and easier tooling management for production environments.
