Boneham SFT2416FX Slip-fixed Drill Bushing 0.1935 in Id

Product Description

The BONEHAM SFT2416FX is a slip-fixed drill bushing in the SF industry code series, designed to guide cutting tools with precision during drilling, reaming, and boring operations in jig and fixture work. The bushing features a 0.1935 inch inside diameter sized for a No. 10 wire gauge drill and a 3/8 inch body outside diameter, with a 1 inch length under head that provides solid tool guidance through the workpiece. Constructed from steel and renewable by design, this head-type bushing locks in place using an LS-TW-2 compatible lock screw. It is installed and removed without disturbing the liner bushing, making it a practical choice for fixtures that require periodic bushing changes across different tool sizes.

Slip-fixed bushings in the SF series are used in production drilling jigs where the bushing must be removable but stays locked during the cut. This part suits metalworking and precision machining environments where hole location accuracy is critical across repeated operations. The head outside diameter of 5/8 inch and head height of 1/4 inch are consistent with standard jig plate seating dimensions. Machinists, tool and die makers, and fixture builders are the primary installers. It fits applications where a renewable, headed, non-counterbored bushing configuration is required and an LS-TW-2 lock screw is already in use or specified for the fixture design.

Key Features

• Slip-fixed (SF) bushing design allows removal and replacement without disturbing the liner

• Steel construction for durability in repeated production drilling applications
• Renewable bushing rated Yes — suitable for fixtures requiring periodic bushing changes
• Head type with 5/8 inch head outside diameter and 1/4 inch head height for positive seating
• Compatible with LS-TW-2 lock screw for secure in-operation retention

Compatibility

Designed for use with LS-TW-2 compatible lock screws in standard jig and fixture plates requiring a slip-fixed, headed drill bushing in the SF series. No specific machine model compatibility was provided by the manufacturer for this part.

Installation Notes

Slip-fixed bushings are installed by tool and die makers or machinists into a press-fit liner bushing already seated in the jig plate. Ensure the fixture plate and liner bushing bore are clean and free of chips before inserting the SF bushing. Engage the LS-TW-2 lock screw to secure the bushing before beginning any drilling operation. Do not use impact tools for installation or removal, as this can damage the bushing bore tolerance or the liner seat.
