Bison 7-168-132 5C Collet 1-1/16 Inch Round

Product Description

The BISON 7-168-132 is a 5C round collet sized to hold workpieces with a 1-1/16 inch diameter. 5C collets are a standard workholding solution used in lathes, collet closers, and indexing fixtures across machine shops and production environments. This collet grips cylindrical stock securely, providing the concentricity and repeatability that precision turning and milling operations require. It is installed and used by machinists and toolroom professionals working with manual or CNC lathes equipped with a 5C spindle nose.

This collet is suited for production turning, secondary operations, and fixture work where consistent grip on 1-1/16 inch round stock is needed. It fits any machine or collet closer designed around the 5C collet standard, which is widely used in both job shop and high-volume manufacturing settings. Applications include bar-fed turning operations, screw machine work, and grinding setups requiring accurate workholding.

Key Features

• 5C collet standard for broad machine compatibility
• Designed to hold 1-1/16 inch diameter round stock
• Provides repeatable, concentric workholding for turning and milling operations
• Suitable for use in collet closers, lathe spindles, and indexing fixtures

Compatibility

Designed as an OEM-style replacement or direct-fit collet for any lathe, collet closer, or indexing fixture built to the 5C collet standard.

Installation Notes

Installation should be performed by a qualified machinist familiar with 5C collet systems. Ensure the spindle or collet closer is fully stopped and de-energized before inserting or removing the collet. Collet bore and workpiece diameter should be matched closely for proper grip and concentricity. Inspect collet seating surfaces for debris or damage before use.
