Parlec C50F-32ERP412 ER32 Collet Chuck CAT50

Product Description

The PARLEC C50F-32ERP412 is an ER32 collet chuck with a CAT50 dual contact taper shank, designed for use in CNC machining centers where rigidity and repeatability are critical. The chuck accepts ER32 collets and features a 4.12-inch projection from gauge line to nose, providing clearance for a wide range of workpiece geometries. Balanced to 20,000 RPM, it is suited for high-speed spindle applications where vibration control directly affects surface finish and tool life. Through-coolant capability delivers cutting fluid directly to the tool tip, improving chip evacuation and thermal management in demanding cutting operations. A 50.00 mm nose diameter and 50.00 mm collet nut diameter complete the primary dimensional profile. Licensed machinists and CNC setup technicians are the typical installers.

This collet chuck is used in horizontal and vertical CNC machining centers equipped with CAT50 spindles. The dual contact taper shank engages both the taper and the spindle face simultaneously, increasing stiffness and reducing runout compared to standard single-contact toolholders. At 4.12 inches of projection, it provides reach for applications requiring clearance around fixtures or deep-pocket features. The through-coolant design is especially effective in aluminum, steel, and stainless steel milling or drilling operations where directed coolant flow reduces heat buildup at the cutting zone.

Compatibility

Designed for use in CNC machining centers with CAT50 dual contact taper spindles accepting ER32 collet toolholders.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Power down and lock out the machine spindle before mounting or removing the toolholder. Use a calibrated torque wrench with the appropriate ER32 collet nut spanner to seat the collet nut to the machine tool builder's specified torque range - do not use impact tools. Verify through-coolant port alignment with the spindle coolant supply before operation.
