Iscar 4561422 ER16 Collet Chuck Modular C6 Through Coolant

Product Description

The ISCAR 4561422 is an ER16 collet chuck designed for precision CNC machining applications requiring reliable tool holding and minimal runout. It accepts ER16 collets with a capacity range of 0.5 mm to 10 mm (0.0197 inches to 0.3937 inches), making it suitable for a wide range of small-diameter cutting tools, drills, and end mills. The chuck features a modular connection shank with a C6 interface, a projection of 3.937 inches (100 mm), and a total indicator runout (TIR) of 0.0001 inches (0.003 mm). Through-spindle coolant capability is built in, supporting high-performance metal cutting operations. This toolholder is installed by machining technicians and CNC setup personnel in production and job shop environments.

This collet chuck is suited for use on CNC machining centers equipped with a C6 modular connection interface. The ER16 collet system is a widely adopted standard, making this chuck compatible with readily available ER16 collets in the specified capacity range. Its through-coolant design supports flood and through-spindle coolant delivery directly to the cutting zone, which is particularly valuable in deep-hole drilling, high-speed milling, and applications where chip evacuation and heat management are critical.

Compatibility

Designed for use on CNC machining centers with a C6 modular connection interface. Accepts standard ER16 collets with a clamping range of 0.5 mm to 10 mm.

Installation Notes

Installation should be performed by a qualified machining technician familiar with modular tooling systems. Ensure the spindle and modular connection interface are clean and free of chips or debris before assembly. Follow the machine tool manufacturer's torque specifications for the modular connection clamping nut. Verify TIR at the collet nose after installation using a dial test indicator before beginning any cutting operation.
