Parlec C40-18DC2 DA180 Double Angle Collet Chuck CAT40

Product Description

The PARLEC C40-18DC2 is a double angle collet chuck designed for precision CNC milling and machining center applications. It accepts DA180 series collets with a capacity range of 0.0313 to 0.75 inches, making it suitable for a wide variety of end mills, drills, and round-shank cutting tools. The chuck mounts via a CAT40 taper shank and delivers a total indicated runout (TIR) of 0.0004 inches, supporting tight-tolerance work. Through-spindle coolant capability channels cutting fluid directly to the tool tip for improved chip evacuation and tool life. Installation and setup are handled by CNC machinists and tool crib technicians.

This collet chuck is used in vertical and horizontal machining centers equipped with CAT40 spindles. It is a standard choice for shops running production milling, drilling, and reaming operations where consistent runout control and coolant-through tooling are required. The 2.95-inch projection provides clearance for workpiece features without excessive overhang. The DA180 collet series is a widely used double angle system suitable for general-purpose and high-speed machining environments.

Compatibility

Designed for use in CAT40 spindle machining centers. Accepts DA180 series double angle collets with shank diameters from 0.0313 to 0.75 inches. Requires a through-spindle coolant-capable machine tool for coolant-through functionality.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before inserting or removing the chuck. Use the correct CAT40 pull stud and the appropriate torque wrench per the machine tool manufacturer specifications when tightening the retention knob. Inspect collet seating surfaces and the taper shank for contamination or wear before assembly to maintain stated TIR performance.
