V-409 Collet chuck – ER-50 collet system with MT-4 taper, 78 mm

V-409 collet chuck for ER-50 collets, designed for secure clamping in machines with an MT-4 taper and compact external dimensions.

• Precise clamping for ER-50 collets
• MT-4 taper for straightforward spindle mounting
• 78 mm external diameter
• Solid 2.2 kg construction

Consistent clamping for repeatable results

The V-409 is engineered to provide precision clamping for ER collet tooling, ensuring repeatable concentricity and dependable tool holding across batches. By using the widely adopted ER-50 collet system, the chuck maintains tight tolerances during machining, which reduces rework and improves first-pass yield. The design focuses on delivering high repeatability, making it suitable for workshops that demand predictable outcome and minimal inspection overhead.

Easy integration with standard taper spindles

A dedicated MT-4 taper ensures a straightforward and secure connection to compatible spindles, simplifying machine set-up and tool changes. The taper interface is designed to seat reliably, transferring torque and axial loads without unnecessary play. This seamless integration reduces downtime during tooling swaps and supports efficient changeover procedures in both single-part and small-series production environments.

Robust dimensions for workshop use

With a compact 78 mm external diameter and a weight of 2.2 kg, the chuck offers a balance between rigidity and manageable mass, suitable for a wide range of machining centres and toolroom lathes. The measured build provides stable support for ER collets while keeping the overall tool envelope modest, which helps preserve clearance and access in crowded spindle noses. The result is a robust construction that withstands daily workshop demands without excessive bulk.

Practical advantages for everyday machining

Employing an ER-50 compatible chuck reduces the number of specialised holders required while enabling fine adjustment of clamping diameters with standard collets. The compact form factor and taper mounting contribute to reduced set-up time and steadier machining conditions, which together increase throughput and lower per-part labour. For operations prioritising consistent cycle times and reliable clamping, this solution offers measurable productivity benefits.
