Value Collection 530-4322 5C Hex Steel Collet 11/32 in

Product Description

The VALUE COLLECTION 530-4322 is a 5C hex collet machined from steel, designed to grip hex-profile workpieces in 5C-compatible spindles and collet chucks. At 11/32 inch across flats, it accommodates hex stock and hex-shank tooling with a total indicator runout (TIR) of 0.0005 inches, providing the concentricity control that precision turning and milling operations require. The internal thread measures 1.041 inches-24 and the external thread measures 1.242 inches-20, both standard 5C dimensions. Machinists and tool-room technicians install this collet in manual lathes, CNC lathes, and collet-chuck setups where secure, repeatable hex-workpiece location is needed.

This collet is suited for production and job-shop environments running hex bar stock, hex-shank cutting tools, or hex fastener blanks. It is appropriate for light to medium turning, secondary operations, and screw-machine work where a 5C spindle nose is present. The hex profile prevents workpiece rotation under cutting load without the need for additional clamping fixtures, making it a practical choice for high-volume repetitive operations as well as prototype work.

Key Features

• Hex collet profile grips hex stock and hex-shank tooling without rotation
• 0.0005 inch TIR for precise, repeatable workpiece concentricity
• 1.041 inch-24 internal thread and 1.242 inch-20 external thread match standard 5C dimensions
• Steel construction provides durability under repeated clamping cycles
• 11/32 inch hex capacity fits common hex bar and fastener blank sizes

Compatibility

Designed as an OEM-style replacement and standard fitment collet for 5C-compatible spindles, collet chucks, and collet closers used in manual and CNC lathe applications.

Installation Notes

5C collets are installed and removed by licensed machinists or qualified tool-room personnel. Ensure the spindle or collet chuck is fully stopped and the machine is locked out before inserting or removing the collet. Clean the spindle bore and collet taper thoroughly before installation to prevent false TIR readings caused by chips or debris. Do not exceed the rated clamping force of the collet closer, as over-tightening can distort the collet and degrade runout performance.
