Kennametal 1016411 Double Angle Tap Collet Series J

Product Description

The KENNAMETAL 1016411 is a double angle tap collet designed for use in Series J tap holders. It accepts hand taps with a collet size of 0.141 inches and a square drive size of 0.110 inches. The collet delivers a total indicator runout (TIR) of 0.001 inches, supporting accurate tap alignment and thread quality in precision machining applications. Sized for 1/8 tap sizes in the 0-6 range, this collet is a direct-fit component for tooling setups where repeatable tap concentricity is required. Installation and replacement are performed by machining professionals and tool crib technicians working with tapping heads and CNC or manual drilling equipment.

This collet is suited for hand tapping operations in production and job shop environments where Series J tap holders are in use. It is appropriate for light-duty tapping of small-diameter threads, typically in metals and engineered materials where thread accuracy and low runout are priorities. The 0.141-inch collet size targets fine-thread and miniature tap applications common in precision manufacturing, mold work, and component fabrication.

Installation Notes

Installation is performed by qualified machining or toolroom personnel familiar with tap holder systems. Ensure the tap holder and spindle are fully de-energized and at rest before removing or installing collets. Verify collet size matches the tap shank diameter and square dimensions before assembly to avoid misalignment or tool damage. Follow the tap holder manufacturer's seating and torque guidelines for the collet nut.
