Jet 650132 R-8 Collet Set 6-piece 1/8 to 3/4 Inch

Product Description

The JET 650132 is a 6-piece R-8 collet set designed for use with milling machines that accept the R-8 taper spindle interface. The set covers a range of shank sizes from 1/8 inch through 3/4 inch in 1/8-inch increments, giving the machinist six collets in a single kit. R-8 collets secure cutting tools, end mills, and drill chucks directly in the spindle, transmitting torque while maintaining concentricity. This set is a practical solution for shops equipping a new mill or replacing worn collets across a working size range.

This collet set is suited for manual vertical knee mills and similar machines using the R-8 spindle standard, which is common in light industrial and job-shop environments. Machinists, tool-and-die workers, and skilled tradespeople who operate Bridgeport-style or comparable mills will find this set covers the most frequently used shank diameters in everyday milling and drilling work.

Key Features

• 6-piece set covering 1/8, 1/4, 3/8, 1/2, 5/8, and 3/4 inch shank sizes
• R-8 taper interface compatible with standard vertical knee mill spindles
• 1/8-inch increment progression covers the most common cutting tool shank diameters
• Single-kit solution reduces the need to source individual collets separately

Compatibility

Designed as an OEM-style replacement or shop-setup collet set for milling machines equipped with R-8 taper spindles.

Installation Notes

R-8 collets are installed and removed by a licensed machinist or qualified mill operator. Always disengage power and confirm the spindle is fully stopped before changing collets. Use the appropriate drawbar and collet wrench for the machine; never use impact tools on the drawbar. Inspect collet bore and taper surfaces for wear or damage before each use to ensure proper tool retention.
