Iscar 4561351 ER16 Collet Chuck Modular C6 Through Coolant

Product Description

The ISCAR 4561351 is an ER16 collet chuck designed for precision machining applications requiring tight runout tolerances and reliable clamping across a range of tool diameters. It accepts ER16 collets with a capacity range of 1 mm (0.0394 inches) to 10 mm (0.3937 inches), making it suitable for a wide variety of end mills, drills, and reamers in that size range. The chuck features a C6 modular connection shank, a projection of 3.937 inches (100 mm), and a nose diameter of 1.1024 inches (28 mm). Total indicated runout (TIR) is 0.0001 inches (0.003 mm), supporting accurate cutting tool positioning. Through-spindle coolant delivery is supported, directing coolant to the cutting zone for improved chip evacuation and tool life.

This collet chuck is intended for use on machining centers and mill-turn platforms equipped with a C6 modular connection interface. It is well suited for light to medium milling, drilling, and reaming operations in metalworking environments, both job shop and production. The C6 modular shank allows the chuck to be used with compatible modular tooling systems, providing flexibility for shops that standardize on modular setups. Machinists and tooling specialists in manufacturing environments are the primary installers and configurators of this toolholder.

Installation Notes

This toolholder is configured by a machinist or tooling technician on a CNC machining center or mill-turn platform. The machine spindle must be fully stopped and the tool change protocol completed before mounting or removing the chuck. Torque the collet nut using the appropriate ER16 collet wrench to the toolholder manufacturer's standard procedure. Verify TIR with a test indicator after assembly before commencing cutting operations.
