Parlec 100RPG-0687 Coolant Single Angle Collet Tg/pg 100

Product Description

The PARLEC 100RPG-0687 is a coolant single angle collet designed for use in TG/PG 100 series toolholding systems. It accepts a 0.6875 inch (11/16 inch) tool shank and delivers a total indicator reading (TIR) of 0.0005 inches, supporting precise, repeatable runout performance in production machining environments. The collet measures 2.375 inches in overall length with a maximum body diameter of 1.379 inches and is rated for coolant pressure up to 600 psi. It is installed by machinists and tooling technicians on CNC machining centers and milling equipment where through-coolant capability is required.

This collet is suited for CNC machining centers and vertical or horizontal milling setups running TG/PG 100 toolholders. The coolant-through design directs cutting fluid directly to the cutting zone, making it appropriate for high-speed or deep-cavity milling, drilling, and reaming operations where flood coolant alone is insufficient. The 11/16 inch bore accommodates standard shank tooling at that diameter. This part is used in both production shops and job shops requiring accurate, coolant-fed tool retention in the TG/PG 100 platform.

Key Features

• 0.0005 inch TIR for consistent runout control in precision machining
• Coolant-through design rated to 600 psi for direct cutting zone fluid delivery
• 0.6875 inch (11/16 inch) bore fits standard shank tooling at that diameter
• 1.379 inch maximum body diameter conforms to TG/PG 100 series specifications
• 2.375 inch overall length provides standard TG/PG 100 collet reach

Compatibility

Designed for use with TG/PG 100 series collet toolholders requiring a 0.6875 inch bore coolant single angle collet.

Installation Notes

Installation and removal should be performed by a qualified machinist or tooling technician with the spindle powered down and locked out per facility lockout/tagout procedures. Use the appropriate TG/PG 100 collet nut and spanner wrench rated for this series. Verify coolant passages are clear before assembly and confirm the collet seats fully and evenly in the holder before torquing the nut. Check TIR with a dial indicator after installation to confirm runout is within specification before beginning a cut.
