Value Collection 220-2222 Manual Offset Boring Head

Product Description

The VALUE COLLECTION 220-2222 is a manual offset boring head designed for precision boring operations on milling machines and machining centers. With a 2-inch body diameter and an integral shank mounting system, this unit accepts a 3/4-inch straight shank for direct spindle connection. The manual actuation allows the operator to dial in precise offsets without auxiliary power or tooling. This type of boring head is installed and adjusted by machinists and tool-and-die technicians performing finish boring, line boring, or interpolated hole sizing on ferrous and non-ferrous workpieces.

This boring head is suited for manual mills, CNC machining centers, and horizontal boring applications where a repeatable, adjustable offset is required. The integral shank design eliminates the need for a separate arbor in compatible setups, reducing stack height and improving rigidity. It is appropriate for job shops, maintenance machining environments, and production facilities running moderate-volume boring operations. The 12-piece set configuration provides tooling variety for a range of bore diameters within the head's working range.

Key Features

• 2-inch body diameter provides a stable platform for offset boring across a wide bore range
• Manual actuation gives the operator direct, tool-free offset adjustment at the machine
• 3/4-inch straight shank with integral mount reduces setup complexity and improves concentricity
• 12-piece configuration supplies multiple boring bars or inserts for varied bore diameter requirements
• Compact integral shank design minimizes overhang and improves chatter resistance during cuts

Compatibility

Designed as an OEM-style replacement and standard-fitment boring head for milling machines and machining centers that accept a 3/4-inch straight shank tool holder with integral shank mounting.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Power down and lock out the machine spindle before inserting or removing the boring head from the spindle nose or tool holder. Ensure the straight shank is fully seated and the drawbar or set screw is torqued to the machine manufacturer's specification before beginning any cut. Verify runout with a dial indicator after mounting and before taking finish passes.
