Kennametal 1016465 Double Angle Tap Collet Series K

Product Description

The KENNAMETAL 1016465 is a double angle tap collet in the K series, designed to hold hand taps securely during tapping operations on CNC machining centers and manual tapping heads. The collet accepts a tap with a 0.168 inch shank diameter and a 0.131 inch square drive size, providing positive drive engagement and accurate tap alignment. With a total indicator runout (TIR) of 0.001 inches (0.030 mm), this collet delivers the concentricity required for clean thread formation and extended tap life. It does not support through-coolant or tension-compression float, making it a fixed, rigid-drive solution suited for stable, controlled tapping applications.

This collet is intended for use in rigid tapping setups where hand taps are driven into pre-drilled holes in metal, plastic, or composite workpieces. It is most commonly installed by machinists and toolroom technicians in job shop, production, and maintenance environments. The K series double angle design seats firmly in compatible K series tap holders, ensuring repeatable positioning across multiple tool changes. Applications include threading operations on ferrous and non-ferrous materials where tight positional tolerance and minimal runout are required.

Key Features

• Double angle collet geometry provides secure, concentric tap seating in K series holders
• 0.168 inch collet bore accommodates standard hand taps at that shank diameter
• 0.131 inch square drive size engages the tap drive square for positive rotational coupling
• TIR of 0.001 inches (0.030 mm) supports accurate thread formation and tap longevity
• Rigid drive design — no tension or compression float — suited for CNC rigid tapping cycles
• No through-coolant path keeps the design compact for standard tapping head configurations

Compatibility

Designed for use with K series tap holders that accept double angle tap collets. Compatible with hand taps requiring a 0.168 inch shank diameter and a 0.131 inch square drive.

Installation Notes

Installation is performed by machinists or tooling technicians. Ensure the tapping head or holder is fully de-energized and the spindle is locked before inserting or removing the collet. Clean the collet bore and holder taper before assembly to ensure full seating and accurate runout. Follow machine tool manufacturer torque guidance for the collet retention nut — do not over-tighten, as this can distort the collet bore and increase runout.
