Accupro 778992 Boring Head CAT50 Taper Shank

Product Description

The ACCUPRO 778992 is a taper shank boring head designed for precision boring operations on CNC machining centers. It features a CAT50 taper interface and a threaded mount with a 1-1/2-18 thread size, providing a rigid and repeatable connection between the spindle and the boring head assembly. With a projection of 1.75 inches, it positions the cutting tool at a consistent working distance from the spindle face. This boring head is installed and operated by machinists and tooling technicians working with CAT50-equipped vertical or horizontal machining centers where accurate bore sizing is required.

This boring head is suited for use in production and job-shop environments running CAT50 tooling. It is appropriate for applications requiring tight bore tolerances in ferrous and non-ferrous materials. The threaded mount interface allows for straightforward assembly to compatible boring head bodies. Coolant-through capability is not included in this configuration. Typical applications include finish boring, semi-finish boring, and diameter adjustment work performed on CNC machining centers with CAT50 spindles.

Key Features

• CAT50 taper shank for direct spindle mounting on compatible machining centers
• Threaded mount size of 1-1/2-18 for secure boring head body attachment
• 1.75 inch projection from spindle face to mounting interface
• No coolant-through design simplifies setup and reduces system requirements
• Compact package dimensions support organized tool crib storage

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers equipped with a CAT50 spindle interface accepting a 1-1/2-18 threaded boring head mount.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. The machine spindle must be fully powered down and the tool changer disabled before mounting or removing taper shank tooling. Use a clean, dry taper bore and shank contact surface to ensure full seating and accurate runout. Follow the machine tool manufacturer torque and drawbar retention specifications when securing the taper shank in the spindle.
