Value Collection R8/HOLDER Set R8 Collet Set 11 Pc

Product Description

The VALUE COLLECTION R8/HOLDER SET is an 11-piece R8 collet set covering a capacity range of 0.125 inches through 0.750 inches. Designed for use with Bridgeport-style and compatible R8-spindle knee mills, this set gives machinists and tool-room operators a full range of workholding collets in a single package. The set includes a turn rack to organize and store all 11 collets when not in use. At 6.92 pounds, the kit is substantial enough to handle daily shop use. It is suited for production machining, maintenance shops, and vocational training environments where R8 tooling is the standard spindle interface.

This collet set is intended for vertical milling machines equipped with an R8 spindle taper, which is the most common spindle standard found in manual knee mills used in job shops, tool rooms, and fabrication facilities. The 11-piece range allows the operator to chuck straight-shank end mills, drills, boring heads, and other tooling across the full 1/8 to 3/4 inch capacity range without switching collet systems. The included turn rack keeps collets indexed and accessible at the machine.

Installation Notes

R8 collets are installed and removed by a trained machinist or toolroom technician. Always power down and lock out the milling machine before changing collets. Use the appropriate drawbar wrench to tighten the drawbar to the collet; do not over-torque by striking the wrench. Inspect collet bore and shank for chips or damage before seating tooling to ensure accurate runout.
