V-741K Collet chuck with steep taper — ER-16, 28 mm

The V-741K is a compact collet chuck engineered for precise clamping of ER collets in confined machining environments.

• Steep taper for secure ER-16 collets
• Compact 28 mm outer diameter
• Precise clamping for high repeatability
• Lightweight 0.45 kg construction

Consistent, repeatable clamping for productive machining

The steep taper seating of this collet chuck provides a stable interface for ER collets, translating into repeatable clamping and reduced positional variation during serial production. By converting the axial draw-in into uniform radial pressure, the design minimises micro-movements at the toolholder interface. This behaviour benefits applications where consistent concentricity and predictable tool performance are required, such as high-precision drilling and light milling operations. The result is fewer reworks and a more predictable process window for small-batch and series production.

Compact footprint that improves access and rigidity

A reduced outer diameter of 28 mm and a slim profile make the chuck suitable for toolholders and spindles with limited clearance. The compact form reduces overhang and helps preserve the stiffness of the overall tool assembly, which in turn supports better surface finish and dimensional control. In confined setups, reduced bulk means faster tool changes and easier integration into multi-spindle heads or short-reach toolholders, giving machine shops efficiency gains without compromising machining quality.

Lightweight construction with straightforward compatibility

At approximately 0.45 kg, the assembly keeps rotating mass low, helping to reduce spindle load and vibration at higher speeds. Compatibility with ER-16 collets ensures a wide range of tool shank diameters can be accommodated with standard collet sets, simplifying stockkeeping and tool management. Manufactured by Vertex, the chuck is intended as a practical component for workshops seeking dependable clamping performance and straightforward interchangeability with established collet systems.

FAQ

How does the steep taper affect clamping performance?
The steep taper in the V-741K concentrates axial draw-in into uniform radial pressure on the ER collet, improving seating stability and therefore clamping repeatability during machining.

Which collet series is compatible with this chuck?
This chuck is designed for use with ER-16 collets, allowing standard ER-16 collet sets to cover a range of tool shank diameters.

Can the compact diameter improve toolholder rigidity?
Yes, the reduced 28 mm profile helps to minimise overhang and maintain a stiffer assembly, which supports better dimensional control and surface quality.
