Accupro 12641803224 Manual Offset Boring Head 2 in

Product Description

The ACCUPRO 12641803224 is a manual offset boring head designed for precision boring operations on milling machines and machining centers. With a 2 inch body diameter and a 1/2 inch boring bar hole diameter, this head accepts standard boring bars and allows the operator to dial in precise offsets by hand. The threaded mount uses a 7/8-20 thread interface for secure attachment to the machine spindle. It is intended for use by machinists and tool-and-die professionals performing finish boring, roughing, or back-boring work where tight diameter control is required.

This boring head is suited for manual mills and CNC machining centers where the operator sets and adjusts the boring offset directly at the tool. The 2 inch body size positions it for light to medium boring work in a shop or production environment. The 7/8-20 threaded mount is a widely used spindle interface in this class of tooling, making it compatible with a range of machine spindle adapters and boring bar extensions.

Key Features

• 2 inch body diameter for light to medium boring applications
• 1/2 inch boring bar hole accepts standard 1/2 inch shank boring bars
• Manual offset actuation for direct, hands-on diameter adjustment

Compatibility

Designed as an OEM-style replacement or direct-fit boring head for milling machine spindles and machining center adapters with a 7/8-20 threaded interface.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before mounting or removing the boring head. Thread the 7/8-20 mount fully onto the spindle adapter and verify the connection is secure before inserting a boring bar. Always set boring offsets with the spindle stopped and confirm runout with a dial indicator before taking a cut.
