Jet 650133 R-8 Collet Set with Rack 6 Piece

Product Description

The JET 650133 is a 6-piece R-8 collet set designed for use with milling machines that accept the R-8 spindle taper. The set includes a storage rack that organizes and protects the collets when not in active use. R-8 collets provide a direct, rigid workholding connection between the spindle and cutting tools, reducing runout and improving cut accuracy. This set is intended for machinists and tool-and-die professionals working on Bridgeport-style and compatible vertical milling machines. The included rack keeps the collets indexed and accessible at the machine, reducing setup time during tool changes.

This collet set is suited for job shops, maintenance facilities, and educational machine shops running vertical knee mills with R-8 spindles. The 8ths sizing designation indicates the set covers collet sizes incremented in one-eighth-inch steps, allowing the operator to chuck a range of straight-shank cutting tools and toolholders. It is a practical starting set for a machine being equipped for general milling work.

Key Features

• 6-piece R-8 collet set sized in one-eighth-inch increments
• Includes a storage rack to organize and protect collets between uses
• R-8 taper provides rigid, low-runout workholding in compatible vertical mills

Compatibility

Designed as an OEM-style fit for vertical milling machines equipped with an R-8 spindle taper, the most common spindle standard on Bridgeport-style knee mills.

Installation Notes

R-8 collets are installed and removed by a licensed machinist or qualified mill operator. Always power down and lock out the milling machine spindle before changing collets. Use the correct drawbar wrench to seat and secure each collet; never use impact tools on the drawbar. Inspect collet bores and tapered surfaces for chips or damage before each use to maintain proper tool concentricity.
