Accupro 12633404873 Boring Head Straight Shank Threaded Mount

Product Description

The ACCUPRO 12633404873 is a straight-shank boring head with a threaded mount, designed for precision internal boring operations on machining centers and manual mills. The shank measures 1-1/4 inches in diameter, and the threaded mount uses a 1-1/2-18 thread specification. Weighing 2.2 pounds, this boring head is built for rigidity and accurate material removal in ferrous and non-ferrous workpieces. Coolant-through capability is not included. Licensed machinists, tool and die makers, and CNC operators install and use this tooling in production and job-shop environments.

This boring head is suited for use on vertical machining centers, knee mills, and similar machine tool setups where a straight-shank, threaded-mount boring tool is required. The 1-1/2-18 threaded mount provides a secure, repeatable interface to compatible boring bar bodies and heads. It is appropriate for both roughing and finishing passes on bored holes, depending on insert selection and feed-speed parameters set by the operator.

Key Features

• Straight shank design with 1-1/4 inch shank diameter for direct spindle or tool holder mounting
• 1-1/2-18 threaded mount for secure and repeatable head-to-shank connection
• No coolant-through configuration keeps setup straightforward for standard boring applications
• Compact and rigid at 2.2 pounds, reducing vibration during boring passes
• UNSPSC Code 27112800 for streamlined procurement classification

Compatibility

Designed as an OEM-style replacement or standard tooling addition for machine tool setups requiring a straight-shank boring head with a 1-1/2-18 threaded mount and 1-1/4 inch shank diameter.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC operator familiar with boring head tooling. Ensure the machine spindle is fully stopped and locked out before mounting or removing the boring head. Verify that the threaded mount interface is clean and free of chips or burrs before assembly to ensure proper seating. Follow the machine tool manufacturer guidelines for tool overhang and runout tolerances before beginning a boring operation.
