Bison 7-168-052 5C Collet 7/16 Inch Round

Product Description

The BISON 7-168-052 is a 5C collet sized for 7/16-inch round stock. 5C collets are precision workholding devices used in lathes, collet closers, and indexing fixtures to grip cylindrical workpieces concentrically during turning, milling, or grinding operations. This collet accepts round stock at 7/16 inches and delivers the repeatable, accurate grip that production and toolroom environments demand. Machinists and toolroom technicians rely on 5C-style collets for fast changeovers and consistent part concentricity across high-volume runs.

This collet is suited for manual and CNC lathes equipped with a 5C spindle nose, as well as bench-top collet fixtures and spin indexers used in job shops and production facilities. The 7/16-inch round capacity covers a wide range of common shaft and bar stock diameters used in general machining work. It is a direct-fit replacement for any standard 5C collet of the same bore size.

Key Features

• 5C collet standard - compatible with the widely used 5C spindle and collet-closer ecosystem
• 7/16-inch round bore for gripping cylindrical workpieces and bar stock
• Precision ground for consistent concentricity and secure workholding
• Compact collet form factor supports fast tooling changeovers

Compatibility

Designed as a standard 5C-style collet replacement for lathes, collet closers, spin indexers, and fixtures that accept the 5C collet form factor with a 7/16-inch round bore capacity.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before inserting or removing any collet. Ensure the collet bore, spindle taper, and collet closer drawbar threads are clean and free of chips or burrs before seating the collet. Do not exceed the rated grip capacity of the collet, as oversize stock can crack the collet body.
