Accupro 778620 Rigid Tapping Chuck BT40 9/16 Inch

Product Description

The ACCUPRO 778620 is a rigid tapping chuck designed for taper shank tooling systems using a BT40 taper interface. It holds taps up to 9/16 inch capacity and provides a projection of 2.95 inches from the gauge line. The quick-change design speeds up tap swaps during production runs. This chuck is intended for use on CNC machining centers and tapping machines where consistent thread quality and rigid tap alignment are required. Licensed machinists and CNC operators install and configure this tooling in machine shops and production environments.

This chuck suits applications on BT40-spindle CNC machining centers performing rigid tapping cycles. The 9/16 inch maximum tap capacity covers common inch-size taps used in ferrous and non-ferrous materials. The Size 1 tap adapter interface provides a standardized connection between the chuck body and the tap holder. It is appropriate for both job-shop and high-volume production tapping operations where rigid tapping mode is available on the machine control.

Key Features

• Rigid tapping style eliminates the need for tension-compression float, supporting synchronous tapping cycles
• BT40 taper shank for direct mounting in BT40-spindle machining centers
• 9/16 inch maximum tap capacity accommodates a wide range of common inch-size taps
• 2.95 inch projection provides clearance for most standard workpiece setups
• Quick-change design reduces tap changeover time during production runs
• Size 1 tap adapter connection for standardized tap holder compatibility

Compatibility

Designed for use with BT40-spindle CNC machining centers equipped with rigid tapping capability. Accepts Size 1 tap adapters as specified in the input data. No additional specific model compatibility data was provided.

Installation Notes

Installation and removal of tapping chucks should be performed by a qualified machinist or CNC setup technician with the machine powered down and the spindle locked. Follow the machine tool manufacturer guidelines for BT40 tooling torque and drawbar retention procedures. Inspect the taper bore and chuck taper for nicks, chips, or contamination before seating the chuck in the spindle. Confirm that the machine control is set to rigid tapping mode before running a tapping cycle with this chuck.
