Parlec C50-32ERP612 ER32 Collet Chuck CAT50 Taper

Product Description

The PARLEC C50-32ERP612 is an ER32 collet chuck with a CAT50 taper shank, designed for precision toolholding in CNC machining centers. It accepts ER32 collets with a capacity range of 2 mm to 20 mm (0.0787 to 0.7874 inches), covering a wide variety of cutting tool shank sizes. The chuck offers a 6.12-inch projection from the spindle face, a total indicator runout (TIR) of 0.0002 inches, and is balanced to 20,000 RPM for high-speed machining applications. Through-spindle coolant delivery is supported, directing coolant directly to the cutting edge. Actuation is via wrench on the ER32 collet nut. This toolholder is installed and set up by machinists and CNC toolroom technicians.

The C50-32ERP612 is suited for vertical and horizontal machining centers equipped with CAT50 spindles. The 6.12-inch projection makes it appropriate for applications requiring clearance from the spindle face, such as deep-pocket milling, drilling, or reaming where shorter holders would not reach. The ER32 collet system accommodates a broad range of tool shank diameters, making this chuck a versatile holder for milling cutters, drills, reamers, and taps within the 2 mm to 20 mm range. Through-spindle coolant compatibility supports chip evacuation and tool life in demanding cutting conditions.

Key Features

Compatibility

Designed for use in CNC machining centers with CAT50 spindle interfaces. Accepts standard ER32 collets within the stated 2 mm to 20 mm capacity range.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Power down and lock out the machining center spindle before mounting or removing the toolholder. Use the appropriate CAT50 pull stud and a calibrated torque wrench on the drawbar per the machine tool manufacturer's specification. Verify TIR with a dial test indicator after seating to confirm proper collet and tool engagement before resuming cuts.
