Boneham SFT2412GQ Slip-fixed Drill Bushing Steel

Product Description

The BONEHAM SFT2412GQ is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to the SF industry standard, it features a 0.221 inch inside diameter, a 3/8 inch body outside diameter, and a 3/4 inch length under the head. The headed design and steel construction provide repeatable tool guidance and resistance to wear over high-cycle use. A lock screw seat accepts LS-TW-2 compatible hardware to secure the bushing in the liner. Machinists, toolmakers, and fixture builders install this type of bushing wherever a renewable, removable guide element is required in a drill jig.

The SFT2412GQ is suited for use in production and toolroom environments where drill jigs require a renewable bushing that can be replaced without disturbing the liner or surrounding fixture plate. The slip-fixed configuration allows the bushing to be locked in position during a drilling operation and removed for tool changes or bushing replacement. It is appropriate for use in moderate- to high-volume hole-locating applications across metal fabrication, assembly fixtures, and precision machining setups.

Key Features

• SF industry-standard slip-fixed design for renewable, removable installation in lined jig plates
• 0.221 inch inside diameter with a tight tolerance of +0.0001 to +0.0004 inches for consistent tool guidance
• 3/8 inch body outside diameter and 5/8 inch head outside diameter with a 1/4 inch head height
• 3/4 inch length under the head suits standard jig plate thicknesses
• Steel construction provides wear resistance in repetitive drilling operations
• Compatible with LS-TW-2 lock screws for positive retention during use

Compatibility

Compatible with LS-TW-2 lock screws. Designed as an OEM-style replacement or direct-fit component for drill jigs and fixtures using SF-series slip-fixed liner bushings.

Installation Notes

Installation is performed by toolmakers or machinist-level personnel working with drill jig fixtures. The bushing slips into a pressed liner and is locked with an LS-TW-2 compatible screw before drilling operations begin. Always ensure the mating liner bore is clean and free of chips before seating the bushing. Follow applicable shop safety procedures and power down any associated machinery before servicing jig components.
