Parlec C40-75SC3 Collet Chuck Tg PG75 CAT40 Taper Shank

Product Description

The PARLEC C40-75SC3 is a single angle collet chuck designed for CNC machining centers using CAT40 taper spindles. It accepts TG and PG75 series collets with a clamping range of 0.031 to 0.75 inches, covering a wide range of tool shank diameters in a single toolholder. The chuck provides 3 inches of projection from the spindle face and holds a total indicator runout (TIR) of 0.0002 inches, supporting tight-tolerance milling, drilling, and reaming operations. Through-spindle coolant delivery is supported, directing coolant to the cutting edge for extended tool life and chip evacuation in deep-pocket and high-feed applications. Machinists and CNC setup technicians are the primary users of this toolholder.

This collet chuck is suited for production and job-shop machining environments running CAT40-equipped vertical or horizontal machining centers. The 3-inch projection makes it a practical choice for workpieces requiring clearance past fixtures or elevated clamps. The TG and PG75 collet series it accepts are widely used in industry for their high clamping force and repeatability. Applications include precision milling, drilling, and tapping where runout control and coolant delivery are required. No specific machine model compatibility is stated by the manufacturer for this part.

Compatibility

Designed for use with TG and PG75 series single angle collets on CAT40 taper spindle machining centers. Collet capacity range is 0.031 to 0.75 inches.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or CNC setup technician with the spindle fully stopped and machine power locked out per facility safety procedures. Use the appropriate spanner wrench and toolholder tightening fixture when seating and torquing the collet nut - do not use a vise or unapproved clamping method on the taper shank. Inspect the CAT40 taper and spindle bore for chips, nicks, or contamination before mounting. Verify coolant line connections are secure before enabling through-spindle coolant flow.
