Kennametal 1016464 Double Angle Tap Collet Series J

Product Description

The KENNAMETAL 1016464 is a double angle tap collet in the J collet series, designed to hold and drive hand taps during tapping operations on machining equipment. Built for precision toolholding, it accepts a tap shank with a decimal inch collet size of 0.168 inches and a square drive size of 0.131 inches. The collet delivers a total indicator runout (TIR) of 0.001 inches, supporting accurate tap alignment and thread quality. This collet is installed by machinists and toolroom technicians as part of a J-series collet chuck system used in drilling and tapping applications on mills, drill presses, and CNC machining centers.

This collet is suited for hand tap applications where repeatable holding force and minimal runout are required. It is compatible with J-series collet chuck bodies and supports standard hand tap shank configurations. The part does not include through-coolant capability and is not rated for tension-compression tap holders. Typical use cases include production tapping and repair tapping in metal fabrication, job shop, and maintenance environments.

Compatibility

Designed as a J-series double angle tap collet for use with J-series collet chuck bodies accepting hand tap configurations with a 0.168-inch shank diameter.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine spindle before inserting or removing the collet from the chuck body. Ensure the collet seats fully and evenly in the chuck before tightening to prevent runout issues. Do not use this collet in tension-compression holders or with taps requiring through-coolant delivery.
