Kennametal 1615976 CAT50 Tap Chuck Adapter M14 to M27

Product Description

The KENNAMETAL 1615976 is a taper shank tap chuck adapter designed for use on CAT50 spindles in CNC tapping operations. It accepts taps ranging from M14 (13/16 inch) to M27 (1-3/8 inch), making it well suited for medium to large diameter tapping work. The adapter features through-coolant capability to direct cutting fluid directly to the tap, supporting longer tool life and cleaner threads in production environments. With a projection of 4.81 inches and a nose diameter of 2.81 inches, it provides the reach and clearance needed for a wide range of fixturing setups. Licensed machinists and CNC tooling technicians are the primary installers.

This tap chuck adapter is intended for use in vertical and horizontal machining centers equipped with a CAT50 taper spindle interface. It is most commonly deployed in job shop and production floor environments where medium to large taps are run at controlled feed and speed. The Size 3 adapter designation governs compatibility with the corresponding tap holders in the modular tapping system. Quick-change functionality allows for faster tap swaps during production runs without removing the chuck body from the spindle.

Key Features

• CAT50 taper shank interface for use on standard CAT50 machining center spindles
• Tap capacity range of M14 to M27 (13/16 inch to 1-3/8 inch)
• Through-coolant design channels cutting fluid directly to the tap point
• Quick-change system reduces tap changeover time during production
• 4.81-inch projection provides clearance for a variety of workpiece and fixture configurations
• Size 3 adapter designation for use with matching tap holders in the modular system

Compatibility

Designed for use with CAT50 taper spindle machining centers. Compatible with Size 3 tap holders in the corresponding modular tapping system. Accepts taps from M14 to M27 (13/16 inch to 1-3/8 inch).

Installation Notes

Installation should be performed by a qualified CNC tooling technician or machinist. Power down and lock out the machining center before mounting or removing the chuck adapter from the spindle. Ensure the CAT50 taper and spindle bore are clean and free of chips or debris before seating the adapter. Verify through-coolant port alignment with the machine spindle coolant supply before running.
