Collis Tool 78361 Collet Chuck 1 in Single Angle Straight Shank

Product Description

The COLLIS TOOL 78361 is a straight-shank collet chuck designed for use with Single Angle TG PG100 collets. It accepts collets up to 1 inch capacity and features an overall length of 8-7/8 inches with a 2-7/8 inch projection from the spindle face. The 1-1/2 inch straight shank seats into compatible machine spindles, and the 2-7/16 inch hex diameter allows for wrench actuation during collet changes. This chuck is intended for machinists and toolroom technicians running milling, drilling, or boring operations on CNC or manual machines that accept straight-shank toolholders.

This chuck fits machine tools equipped with straight-shank spindle bores sized for 1-1/2 inch shanks. The 6 inch shank length provides deep engagement for secure retention. With a 2-7/8 inch projection, it keeps tooling close to the spindle nose, reducing overhang and improving rigidity during cutting operations. It does not include through-coolant capability, making it suited for dry or flood-coolant setups where coolant is delivered externally rather than through the tool. Typical applications include production machining environments where TG PG100 collet systems are already in use.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before inserting or removing the chuck. Use the appropriate wrench on the hex flat to seat and tighten collets to the manufacturer-specified procedure. Inspect the shank and collet bore for chips or damage before each use to ensure proper seating and runout performance.
