V-444 Collet Set (ER-25) with MT‑3 Collet Chuck by Vertex

The V-444 is a compact collet set designed to provide precision clamping for milling and drilling spindles with an MT‑3 taper.

• ER‑25 system for high concentricity
• MT‑3 Morse taper for direct spindle fit
• Seven-piece set for versatile clamping
• Robust build suitable for workshop use

Consistent clamping for repeatable results

A reliable production process starts with stable toolholding. The ER‑25 system used here ensures high concentricity, translating into reduced runout and more consistent part geometry. By combining a standard ER collet format with a properly matched chuck, the arrangement reduces vibration transfer to the cutting edge and supports repeatable tolerances across batches. For operations where consistency matters, this solution reduces rework and improves first‑pass yield.

Direct spindle mounting speeds tool changes

Fitted with an MT‑3 Morse taper, the collet chuck mounts directly into compatible spindles without additional adapters, simplifying tool changes and minimising setup time. The Morse taper interface offers secure axial and radial support under typical workshop loads, while the ER‑25 system allows a range of tool shank diameters to be clamped with a single chuck body. This combination supports quick transitions between jobs and keeps machine downtime to a minimum.

Practical design for everyday workshop demands

Built for routine use, the set’s construction focuses on durability and ease of integration into existing workflows. The compact nature of the chuck and the standardised ER‑25 format mean spares and replacements are widely available, which helps maintain uptime. The overall solution is well suited to small series production and general workshop work, where reliable clamping and straightforward maintenance are valued.

Clear advantages for procurement and maintenance

Specifying standard interfaces such as ER‑25 and MT‑3 simplifies procurement and inventory management: one chuck body can accept multiple collets, and the seven‑piece configuration provides basic coverage for common tool diameters. Maintenance routines are straightforward because the system uses established components; technicians experienced with collet systems will find familiar handling and compatibility, reducing training time and possible handling errors.

FAQ

What spindle taper is required for this collet set?
The V‑444 set uses an MT‑3 Morse taper shank, so it requires a spindle or arbor accepting MT‑3 for direct mounting.

How many collets are included in the set?
This Vertex collet set is supplied as a seven‑piece configuration, providing a basic range of ER‑25 clamping options for typical workshop needs.

Is the ER‑25 system compatible with other ER‑type accessories?
Yes, the ER‑25 format is a standard collet system; the V‑444 chuck accepts ER‑25 collets and is compatible with other ER‑25 accessories from standard suppliers.

Will this set improve machining accuracy?
Using the ER‑25 system together with the MT‑3 chuck reduces runout and improves toolholding stability, which contributes to better repeatability and part accuracy in everyday machining tasks.

Can the set be used for both milling and drilling operations?
The combination of ER‑25 collets and an MT‑3 mounting provides versatile clamping suitable for common milling and drilling applications when matched to appropriate machines and tooling.
