Parlec C40-20DC5 Double Angle Collet Chuck CAT40 Taper

Product Description

The PARLEC C40-20DC5 is a double angle collet chuck designed for CNC machining centers using a CAT40 taper shank interface. It accepts DA200 series collets and covers a clamping range of 0.031 to 0.25 inches, making it suited for small- to medium-diameter tooling. The chuck delivers a TIR of 0.0004 inches, supporting consistent concentricity in precision milling and drilling operations. A 5-inch projection from the gauge line provides clearance for deep-pocket and tall-fixture work. Through-spindle coolant capability is built in, directing coolant to the cutting edge without external lines.

This collet chuck is intended for use on CAT40-spindle vertical and horizontal machining centers in production and job-shop environments. It is a practical choice where operators need repeatable tool runout across multiple setups. The DA200 collet system is a widely used double angle standard, and tooling in the 0.031 to 0.25 inch range covers end mills, drills, reamers, and taps common to general metalworking. Installation and tool changes are handled by qualified machining center operators or toolroom technicians.

Key Features

• DA200 double angle collet system for secure radial and axial clamping
• CAT40 taper shank for direct spindle mounting on standard machining centers
• Clamping capacity from 0.031 to 0.25 inches to accommodate a wide tooling range
• TIR of 0.0004 inches for high-concentricity tool holding
• 5-inch projection for clearance in deep-pocket and fixture-intensive setups
• Through-spindle coolant path delivers coolant directly to the cutting zone

Compatibility

Designed for use with CAT40 spindle machining centers and DA200 series collets. Collet capacity range of 0.031 to 0.25 inches determines compatible tooling shank diameters.

Installation Notes

Installation is performed by a qualified machining center operator or toolroom technician. Power down and lock out the machine spindle before mounting or removing the chuck. Use the correct spanner or retention knob torque procedure per the machine tool builder specifications. Verify TIR at the tool tip after clamping before resuming production cuts.
