Parlec C40-32ERP412 ER32 Collet Chuck CAT40 Taper

Product Description

The PARLEC C40-32ERP412 is an ER32 collet chuck with a CAT40 taper shank, designed for precision milling and drilling operations on CNC machining centers. It accepts ER32 collets with a clamping range of 2 mm to 20 mm (0.0787 to 0.7874 inches), covering a wide range of tooling diameters in a single chuck body. The chuck features through-spindle coolant delivery and holds a total indicator runout (TIR) of 0.0002 inches, supporting close-tolerance work. It is balanced to 25,000 RPM, making it suitable for high-speed spindle applications. Machining professionals and CNC setup technicians install this chuck as a standard toolholder in CAT40-spindle machines.

This collet chuck is used in CNC vertical and horizontal machining centers equipped with CAT40 spindle tapers. Typical applications include finish milling, drilling, reaming, and tapping where runout control and coolant-through capability are required. The 4.12-inch projection from gauge line provides clearance for five-axis and deep-cavity work. The wrench-actuated ER32 collet nut allows quick tooling changes on the shop floor. This chuck is well suited to production environments where consistent clamping force and balanced performance at elevated spindle speeds are priorities.

Installation Notes

Installation and removal should be performed by a qualified machinist or CNC toolroom technician. Always power down the spindle and confirm the machine is in a safe, locked-out state before changing toolholders. Clean the CAT40 taper and spindle bore thoroughly before seating the chuck to ensure proper contact and runout performance. Torque the retention knob and collet nut according to the machine tool builder and toolholder manufacturer specifications.
