Boneham SFT366IW Slip-fixed Drill Bushing 0.332 in Id

Product Description

The BONEHAM SFT366IW is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling, reaming, and related machining operations. Built to industry code SF, it features a 0.332-inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches, a 9/16-inch body outside diameter (0.5625 inches), and a 3/8-inch length under the head. The headed design and steel construction make it well-suited for production jig work where repeatable hole location accuracy is required. It is compatible with the LS-TW-2 lock screw, allowing secure retention in the jig plate. This bushing is installed and serviced by machinists, toolmakers, and jig-and-fixture builders.

This slip-fixed bushing is used in drill jig applications across manufacturing and metalworking environments, including production machining, aerospace fabrication, and general tool-and-die work. It seats into a liner bushing already pressed into the jig plate, allowing the bushing to be locked in place during the operation and removed for changeover. Typical applications include close-tolerance drilling and reaming where consistent tool guidance is critical. The renewable design allows the bushing to be replaced independently of the jig plate liner, extending overall fixture life.

Key Features

• Inside diameter of 0.332 inches with a tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• 9/16-inch body outside diameter for standard liner bushing compatibility
• 3/8-inch length under head suits moderate material thickness applications
• Headed design with 7/8-inch head outside diameter and 1/4-inch head height for positive seating
• Steel construction provides wear resistance in production drilling cycles
• Renewable bushing design allows independent replacement without disturbing the liner
• Compatible with LS-TW-2 lock screw for secure retention in the jig plate

Compatibility

Designed for use with LS-TW-2 compatible lock screws and intended to seat in a standard liner bushing per SF bushing industry specifications. No specific jig plate or fixture model compatibility was provided in the product data.

Installation Notes

Installation and replacement should be performed by qualified machinists or toolmakers familiar with drill jig fixture assembly. Before servicing the jig plate or replacing the bushing, ensure all cutting equipment is powered down and the workpiece is properly secured. The bushing should be engaged and locked with the appropriate LS-TW-2 lock screw before beginning any drilling or reaming operation. Do not force the bushing into a liner with an incompatible inside diameter, as this can damage the bore tolerance.
