Parlec C40-25ERP262 ER25 Collet Chuck CAT40 Taper

Product Description

The PARLEC C40-25ERP262 is an ER25 collet chuck designed for precision CNC machining applications. It features a CAT40 taper shank and accepts ER25 collets with a capacity range of 1 mm to 16 mm (0.0394 to 0.6299 inches). The chuck delivers a TIR of 0.0002 inches, supporting tight-tolerance work across a variety of cutting operations. Through-spindle coolant capability directs coolant directly to the cutting zone, extending tool life and improving chip evacuation. With a balance rating of 25,000 RPM, this chuck suits high-speed machining centers used in production environments. Installation is performed by qualified CNC machinists and tool-room technicians.

This collet chuck is suited for vertical and horizontal CNC machining centers equipped with a CAT40 spindle interface. The ER25 collet system accommodates a broad range of shank diameters, making it versatile across drilling, reaming, tapping, and light milling operations. The through-coolant design is particularly effective in deep-hole drilling and high-speed finishing passes where heat and chip buildup are concerns. The wrench-actuated collet nut allows for repeatable tooling changes on the shop floor.

Key Features

• ER25 collet system with 1 mm to 16 mm (0.0394 to 0.6299 inch) capacity range
• CAT40 taper shank for direct spindle mount on standard machining centers
• 0.0002-inch TIR for precise, repeatable tool runout
• Through-spindle coolant delivery directs fluid to the cutting edge
• Balanced to 25,000 RPM for high-speed machining compatibility
• Wrench-actuated collet nut for consistent clamping force

Compatibility

Designed for use with CAT40 spindle machining centers and ER25 series collets. Compatible with through-spindle coolant systems delivering coolant via the spindle centerline.

Installation Notes

Installation and tooling changes should be performed by a qualified CNC machinist or tool-room technician. Power down and lock out the machining center spindle before mounting or removing the chuck. Use the appropriate ER25 collet wrench and spanner to achieve proper clamping torque per the collet nut manufacturer guidelines. Inspect the taper shank and spindle bore for nicks, chips, or contamination before seating the chuck to maintain runout accuracy.
