Boneham SFT288HX Slip-fixed Drill Bushing 9/32 in Id

Product Description

The BONEHAM SFT288HX is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Manufactured from steel, it features a 9/32 inch inside diameter and a 7/16 inch body outside diameter, with a 1/2 inch length under the head. The headed design allows the bushing to seat flush against a jig plate, while the slip-fixed installation method enables quick removal and replacement without permanent press-fit installation. Inside diameter tolerance is held to +0.0001 to +0.0005 inches for consistent tool guidance and hole accuracy.

This bushing is used in drill jig assemblies across manufacturing, machining, and fabrication environments. The SF (slip-fixed) bushing style is standard in applications where bushings must be changed frequently to accommodate different tool diameters or operations at the same hole location. It is compatible with the LS-TW-2 lock screw, which secures the bushing in the jig liner during use. Machinists, toolmakers, and fixture builders working in job shops or production facilities are the primary installers of this component.

Key Features

• 9/32 inch inside diameter with +0.0001 to +0.0005 inch tolerance for precise tool guidance
• 7/16 inch body outside diameter, 5/8 inch head outside diameter, 1/4 inch head height
• 1/2 inch length under head provides adequate bearing surface in standard jig plates
• Steel construction for durability in repeated drilling cycles
• Headed design seats against jig plate face for positive axial location
• Compatible with LS-TW-2 lock screw for secure retention during operation
• Renewable bushing — can be removed and replaced without disturbing the liner

Compatibility

Designed for use with LS-TW-2 compatible lock screws and standard SF-style drill jig liners. Follows the SF bushing industry code for interchangeability with standard slip-fixed liner systems.

Installation Notes

Installation is performed by toolmakers or machinists working with drill jig assemblies. The bushing slides into a press-fit liner already installed in the jig plate and is locked in position using the appropriate LS-TW-2 lock screw. Remove the lock screw before attempting to extract or rotate the bushing. Ensure the liner bore and bushing body are free of chips and debris before seating to avoid damage to the precision-ground surfaces.
