Vertex collet chuck V-318 — R8 shank, ER-40 compatible set

The collet chuck V-318 is a precision toolholding solution with an R8 mounting, engineered for stable clamping in workshop milling spindles and compact machining centres.

• R8 shank for standard milling spindles
• Compatible with ER-40 collets
• Supplied as a set with seven pieces
• Stable mass for improved machining control

Precision clamping for consistent production

The combination of an R8 mount and ER-40 collet compatibility ensures repeatable concentricity and reliable clamping torque, which translates into fewer rework cycles and better surface finishes. The design focuses on mechanical stability: a well-balanced interface between spindle taper and chuck reduces runout and vibration during cutting. For users less familiar with technical terms, R8 denotes a common taper used on many bench and toolroom milling spindles, while ER-40 refers to a widely adopted collet system that accommodates a broad range of tool diameters with uniform clamping pressure. This results in predictable machining performance across different jobs.

Ready-to-use set that speeds up changeovers

Delivered as a complete set, the toolholding solution provides immediate access to multiple clamping sizes, reducing downtime caused by frequent tool changes. The package logic supports medium-sized workshops and service departments that require flexible toolholding without the need for custom adapters. Material removal processes benefit from consistent tool engagement and minimal setup times, contributing to higher machine uptime and a smoother production flow. The compact arrangement of components also simplifies storage and organisation at the bench.

Robust build for stable toolholding and easy integration

With a mass of 4.6 kg, the chuck provides a solid feel that helps dampen cutting forces and stabilise the spindle during heavier passes. The configuration is suited to machines accepting an R8 taper and is compatible with established ER-40 collet ranges, allowing straightforward integration into existing tool inventories. The Vertex design emphasises durability and repeatability rather than superfluous features, delivering dependable clamping where precision counts. Maintenance is simple: routine inspection and cleaning of the taper and collet seats preserve concentricity and prolong service life.
