Value Collection 220-1400 Offset Boring Head 4 in Series F1

Product Description

The VALUE COLLECTION 220-1400 is a manual offset boring head designed for precision boring operations on milling machines and machining centers. With a 4-inch body diameter and a 1-inch boring bar hole diameter, this head accepts standard boring bars for controlled single-point boring cuts. The 1-1/2-18 threaded mount provides a secure, rigid connection to compatible spindle tooling. Manual actuation allows the operator to dial in the boring diameter directly, with a direct-reading graduation of 0.0005 inches per division for repeatable setups. This tool is part of the Series F1 lineup and is suited for use by machinists and toolroom professionals in production and job-shop environments.

The 220-1400 boring head supports a minimum bore diameter of 0.625 inches and a maximum bore diameter of 12.5 inches, covering a wide range of bore sizes in a single setup. It is appropriate for use in general-purpose machining applications including bore enlarging, ID finishing, and precision bore sizing on cast iron, steel, and aluminum workpieces. The threaded mount design is commonly used on knee mills, bed mills, and vertical machining centers equipped with compatible spindle adapters.

Installation Notes

Installation should be performed by a qualified machinist. Power down and lock out the machine spindle before mounting or removing the boring head. Verify that the threaded adapter and spindle interface are clean and free of burrs before assembly. Confirm boring bar setscrew torque and bar extension length before initiating a cut to minimize vibration and tool deflection.
