V-443 Collet Set (ER-25) with MT-3 Arbor by Vertex — 15-piece, 2.5 kg

A V-443 collet set designed to deliver precise clamping for milling and drilling spindles featuring an ER-25 clamping system and an MT-3 taper for direct spindle integration.

Complete 15-piece ER-25 set
Includes MT-3 taper arbor
High repeatability for consistent concentricity
Compact and robust 2.5 kg package

Secure clamping that increases process reliability

The set provides repeatable tool holding through the ER series design, ensuring consistent runout and stable cutting conditions. The clamping system reduces vibration and tool movement, which in turn improves surface finish and extends tool life. This benefit-oriented design supports continuous production runs by limiting the need for frequent rework and readjustment. The construction focuses on functional reliability rather than cosmetic features, making it suitable for industrial environments where stability is essential.

Seamless integration with MT-3 spindles for workshop flexibility

Thanks to the included MT-3 arbor, the chuck integrates directly with machines using a Morse taper spindle, simplifying machine setup and reducing adaptor requirements. Compatibility with common taper standards means reduced downtime when switching between fixtures and faster changeovers. The modular arrangement supports both retrofit and new-equipment use, allowing workshops to standardise on a single clamping family and streamline tooling logistics for higher throughput.

Ready-to-use set that speeds up machining workflows

The 15-piece configuration supplies a practical range of collets in one compact kit, enabling quicker access to the most frequently required sizes and minimising tool change interruptions. The organised set reduces search time and supports efficient scheduling of operations, which is particularly valuable in jobbing shops and production cells where every minute counts. The relatively low mass of the complete kit at 2.5 kg aids storage and transport between workstations without sacrificing robustness.

Built for longevity with straightforward upkeep

Components are designed for workshop conditions, emphasising durability and easy maintenance to keep the system in service longer. Regular cleaning and inspection of the clamping surfaces and taper seating maintain consistent performance; worn parts can be replaced without extensive downtime. The overall design reduces the total cost of ownership through prolonged service intervals and predictable behaviour in demanding applications.
