Kennametal 1615969 CAT40 Tapping Chuck Tap Adapter

Product Description

The KENNAMETAL 1615969 is a taper shank tapping chuck designed as a tap chuck adapter for CNC machining centers. It features a CAT40 modular side connection and accepts taps from M1 through M14 in metric sizing, or up to 9/16 inch in imperial. The unit provides a projection of 2.88 inches and includes through-coolant capability to support coolant delivery directly to the cutting zone. A quick-change design reduces tap changeover time during production runs. This toolholder is installed by machinists and CNC tooling technicians in shop environments running tapping operations on vertical or horizontal machining centers.

The 1615969 is suited for production and job-shop tapping applications on CAT40-spindle machining centers. It accepts a Size 1 tap adapter and accommodates a wide tap size range from M1 to M14, making it appropriate for both fine-pitch and general-purpose threading work. The through-coolant feature supports tapping in materials where heat and chip evacuation are critical concerns. This adapter is a component-style toolholder — it pairs with a compatible tap collet or tap holder insert to complete the assembly.

Key Features

• CAT40 taper shank for direct mounting to CAT40-spindle machining centers
• Tap capacity range: M1 to M14 metric, up to 9/16 inch imperial
• 2.88-inch projection for reach into standard workpiece setups
• Through-coolant capability for chip flushing and heat control at the cutting edge
• Quick-change design reduces tap changeover time in production environments
• Size 1 tap adapter interface with a 0.75-inch (3/4 inch) hole diameter
• 1.26-inch nose diameter for consistent chuck-to-adapter engagement

Compatibility

Designed for use with CAT40-spindle CNC machining centers. Accepts Size 1 tap adapters with a hole diameter of 0.75 inches. Specific machine model compatibility should be confirmed against the spindle taper standard and adapter interface requirements of the target machine.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machining center spindle before mounting or removing any toolholder. Ensure the CAT40 taper and spindle bore are clean and free of chips or coolant deposits before seating the chuck. Torque retention knobs or drawbar fasteners per the machine manufacturer specifications — do not rely on hand-tight assembly alone.
