Collet chuck V-749A — ER-25 steep taper, Ø42 mm (Vertex)

Collet chuck V-749A for secure clamping of ER collets in milling and drilling setups, optimised for precision and repeatability

• ER-25 taper compatibility for ER collets
• Compact Ø42 mm body for tight setups
• Solid 3.4 kg construction for stability
• Ideal for high-precision clamping applications

Reliable clamping that stabilises machining

A compact collet chuck with a steep ER-25 taper delivers consistent axial alignment and repeatable clamping force, reducing tool runout and improving surface finish. The steep taper design transfers clamping forces directly into the spindle interface, increasing contact area and mechanical stability. For workshops seeking predictable results, this configuration supports tighter tolerances and fewer setup adjustments, which in turn reduces cycle times and scrap rates. The unit’s balanced geometry supports productivity in repeated production tasks while the design minimises vibration during cutting operations.

Compact design that fits dense workstations

With a Ø42 mm body and a 3.4 kg mass, the chuck is engineered for installations where space and mass distribution matter. The compact footprint enables use in confined toolholding arrangements and multi-tool setups, while the mass contributes to dampening minor oscillations under load. The straightforward geometry facilitates quick integration into existing tool chains without extensive modification. Maintenance is simplified by the standard ER system: readily available collets and accessories mean minimal downtime when replacing consumables or adapting the clamping diameter.

Clear compatibility and application guidance

The chuck is built for use with standard ER-25 collets, offering a familiar interface for operators and service teams. That compatibility ensures fast tool changes and broad availability of collet sizes to match typical shank diameters. Technical identification such as SKU V-749A and the included machine taper information help maintenance planners and procurement to match the component precisely to the spindle interface. For process planners, this product supports stable machining routines where consistent clamping and precise concentricity are priorities, particularly in small to medium-sized parts production.
