Accupro 778590 Tapping Chuck CAT50 9/16 Inch Capacity

Product Description

The ACCUPRO 778590 is a rigid tapping chuck designed for taper shank tooling setups in CNC machining centers. It accepts a CAT50 taper connection and handles taps up to 9/16 inch in diameter, making it a practical choice for production threading operations where repeatable accuracy matters. The chuck features a quick-change design for fast tap swaps without removing the holder from the spindle. With a projection of 2.95 inches, it provides sufficient clearance for most standard threading applications. Weighing 1 pound, it is a compact, purpose-built holder intended for machinists and tooling technicians working in job shop or production environments.

This tapping chuck is suited for use on CNC machining centers equipped with CAT50 spindle interfaces. It accepts a Size 1 tap adapter, which covers a common range of tap shanks used in general-purpose threading work. Rigid tapping style is appropriate for machines with synchronous spindle control, where the feed rate and spindle RPM are electronically coordinated to eliminate the need for a tension-compression float. Typical applications include tapping holes in ferrous and non-ferrous materials on vertical or horizontal machining centers.

Key Features

• CAT50 taper shank for direct mounting to compatible machining center spindles
• Rigid tapping style for use with synchronous spindle control
• Maximum tap capacity of 9/16 inch for common production threading sizes
• Quick-change function allows fast tap replacement without removing the holder
• Size 1 tap adapter interface for broad tap shank compatibility
• 2.95 inch projection provides clearance for standard threading operations

Compatibility

Designed for use on CNC machining centers with a CAT50 spindle taper. Accepts Size 1 tap adapters. Rigid tapping requires a machine with synchronous spindle-to-feed coordination.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with CAT50 tooling systems. Power down and lock out the machining center before mounting or removing any tooling from the spindle. Use the appropriate pull stud and drawbar torque procedure specified by the machine manufacturer when seating the CAT50 taper. Verify tap adapter retention and runout with a dial indicator before beginning production.
