Kennametal 1016587 Tap Collet Series L 0.367 Inches

Product Description

The KENNAMETAL 1016587 is a double angle tap collet in the L collet series, designed to secure hand taps during tapping operations on machining equipment. Built for precision work, it features a collet size of 0.367 inches and a square drive size of 0.275 inches. The total indicator runout (TIR) is 0.001 inches (0.0300 mm), providing consistent concentricity for accurate thread cutting. This collet is installed by machinists and toolroom technicians in tapping heads and tap holders where repeatable, low-runout tap retention is required.

This collet is suited for use with 1/2-inch hand taps in manual and semi-automatic tapping applications. The double angle collet design provides secure clamping and self-release characteristics typical of the L series tap collet system. It does not support through-coolant delivery and is not designed for tension-compression tap holders. Typical applications include production tapping on drill presses, tapping arms, and CNC machines configured for rigid tapping with compatible L series holders.

Compatibility

Designed for use with 1/2-inch hand taps in KENNAMETAL L series tap holders and tapping heads that accept double angle collets. Verify holder series compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the tapping head or tap holder is fully de-energized and the spindle is locked before inserting or removing the collet. Clean the collet bore and holder seat before assembly to prevent runout caused by debris. Follow the tap holder manufacturer torque and seating procedures for the L series collet interface.
