Parlec C50-15SC4 Collet Chuck CAT50 Single Angle Tg

Product Description

The PARLEC C50-15SC4 is a Single Angle collet chuck designed for precision CNC machining applications. Built on a CAT50 taper shank, it accepts TG and PG150 series collets with a capacity range of 0.484 to 1.500 inches. The chuck delivers a total indicator runout (TIR) of 0.0002 inches, making it well-suited for applications where concentricity directly affects tool life and surface finish. Projection from gauge line measures 3.5 inches with an overall length of 7.5 inches. Through-coolant capability allows coolant delivery directly to the cutting zone. Licensed machinists, CNC setup technicians, and tool crib personnel are the primary installers.

This collet chuck is intended for use in vertical and horizontal machining centers equipped with CAT50 spindle interfaces. The Single Angle collet system using TG and PG150 series collets is common in production shops running milling, drilling, and reaming operations where consistent grip force and repeatable runout are required. The through-spindle coolant path supports high-speed machining strategies that rely on flood coolant at the cutting edge to manage heat and chip evacuation.

Key Features

• CAT50 taper shank for direct spindle mounting on standard 50-taper machining centers
• Accepts TG and PG150 series Single Angle collets from 0.484 to 1.500 inches diameter
• TIR of 0.0002 inches for high-precision concentricity
• 3.5 inch projection from gauge line for extended reach applications
• Through-spindle coolant delivery to the cutting zone
• Nose diameter of 3.430 inches

Compatibility

Compatible with TG and PG150 series Single Angle collets. Designed for use in CAT50 spindle machining centers. Confirm spindle interface and collet series with machine documentation before installation.

Installation Notes

Installation and tooling changes should be performed by qualified CNC setup or machine tool personnel with the spindle at a full stop and machine power locked out per facility lockout/tagout procedures. Clean the taper bore and shank mating surfaces thoroughly before seating to ensure accurate runout. Use a calibrated torque wrench and appropriate spanner to tighten the collet nut to the toolholder manufacturer's specification. Verify runout with a dial test indicator after assembly before returning the spindle to production.
