Kennametal 1016471 Double Angle Tap Collet Series K

Product Description

The KENNAMETAL 1016471 is a double angle tap collet in the K series, designed to hold hand taps securely in compatible tapping chucks and holders. With a collet size of 0.22 inches and a square size of 0.165 inches, it is engineered for accurate tap retention during threading operations. The total indicator runout (TIR) is 0.001 inches, supporting precise, concentric tap alignment that reduces thread form error and tap breakage. This collet is installed by tool crib technicians, machinists, and maintenance professionals working on manual or CNC-assisted tapping setups.

This collet is suited for hand tap applications where a K-series double angle collet is specified. The 0.22-inch collet size accommodates taps in that decimal range, and the 0.165-inch square drive dimension matches the square shank of the held tap. It is appropriate for use in ferrous and non-ferrous machining environments where tap accuracy and repeatability are required. No through-coolant or tension-compression functionality is included, making it a straightforward rigid-holding collet for standard hand tapping work.

Key Features

• Double angle collet design for secure, repeatable tap seating in K-series holders
• 0.001-inch TIR for precise tap concentricity and reduced thread form error
• 0.22-inch collet bore size accommodates matching hand tap shank diameters
• 0.165-inch square drive size matches standard tap square shanks
• No through-coolant or tension-tap features — rigid holding for standard hand tapping

Compatibility

Designed for use with K-series double angle tap collet holders that accept hand taps with a 0.22-inch shank diameter and 0.165-inch square drive.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the tapping chuck 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 seating to prevent runout caused by chips or contamination. Follow the machine tool manufacturer's clamping torque guidelines for the specific holder type.
