Accupro 778988 Boring Head CAT40 Taper Shank Threaded Mount

Product Description

The ACCUPRO 778988 is a taper shank boring head designed for precision boring operations on CNC machining centers. It mounts via a CAT40 taper interface with a 1-1/2-18 threaded mount, providing a secure, repeatable connection between the spindle and the boring head body. The 1.75-inch projection positions the cutting tool at the correct axial distance for standard boring applications. Weighing 2.7 pounds, the unit is built for rigidity under cutting loads. This boring head is installed and serviced by machinists and toolroom technicians working with vertical or horizontal machining centers equipped with CAT40 spindles.

This boring head is suited for production and job-shop environments where precise diameter boring is required on ferrous and non-ferrous materials. The CAT40 taper is one of the most widely used spindle interfaces in North American CNC machining, making this tool compatible with a broad range of machining center platforms. The 1.75-inch projection accommodates typical boring bar setups for through-hole and blind-hole applications in standard workpiece configurations.

Key Features

• CAT40 taper shank for direct spindle mounting on CNC machining centers
• 1-1/2-18 threaded mount for positive boring head attachment
• 1.75-inch projection for standard boring bar reach
• No coolant-through design - suitable for external coolant delivery setups
• Compact 2 x 2 x 7 inch package dimensions for easy storage and transport

Compatibility

Designed as a direct-mount boring head shank for CNC machining centers with CAT40 spindle interfaces and 1-1/2-18 threaded boring head bodies.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machining center spindle before mounting or removing the taper shank. Ensure the CAT40 taper and spindle bore are clean and free of chips or contamination before seating the shank. Torque the drawbar to the machining center manufacturer's specification - do not estimate drawbar engagement by feel alone.
