Value Collection 530-4354 5C Hex Steel Collet 27/32 in

Product Description

The VALUE COLLECTION 530-4354 is a 5C hex collet machined from steel, designed to hold hex-profile workpieces in 5C-compatible spindles and collet chucks. It accepts a 27/32 inch hex stock size and delivers a total indicator reading (TIR) of 0.0005 inches, providing consistent, repeatable workholding accuracy for turning, milling, and secondary operations. The internal thread is 1.041 inches-24 and the external thread is 1.242 inches-20, conforming to standard 5C collet geometry. This collet is installed by machinists and tool-room technicians in manual and CNC lathes or dedicated 5C collet fixtures.

This hex collet is suited for production and job-shop environments where hex bar stock or hex-profile parts must be held securely without jaw marks. Typical applications include screw machine operations, Swiss-style turning setups, and secondary ops on pre-cut hex blanks. The steel construction handles the clamping loads and repeated use cycles common in production machining. It fits any machine equipped with a standard 5C spindle nose or 5C collet chuck.

Key Features

• Hex collet profile holds 27/32 inch hex workpieces without marring
• 0.0005 inch TIR for precise, repeatable workholding
• 1.041 inch-24 internal thread and 1.242 inch-20 external thread match standard 5C collet dimensions
• Steel construction withstands repeated clamping cycles in production environments
• Compatible with all standard 5C spindle noses and collet chucks

Compatibility

Designed as a standard 5C hex collet replacement or addition for any lathe, collet chuck, or fixture built to accept 5C-style collets with 1.242 inch-20 external thread geometry.

Installation Notes

5C collets are installed by qualified machinists. Before inserting or removing a collet, disengage the spindle drive and confirm the machine is fully powered down and locked out per facility LOTO procedures. Inspect the spindle bore and collet taper for chips or burrs before seating the collet, as contamination directly affects TIR. Do not exceed the rated hex capacity of 27/32 inch, and do not use a collet on round stock without the appropriate round-profile collet.
