Boneham SFT245FZ Slip-fixed Drill Bushing 0.196in Id Steel

Product Description

The BONEHAM SFT245FZ is a slip-fixed drill bushing designed to guide cutting tools accurately during drilling, reaming, and similar machining operations. Classified under industry code SF, this bushing features a 0.196 inch inside diameter and a 3/8 inch body outside diameter with a 5/16 inch length under head. It is manufactured from steel for durability in repetitive production environments. The headed design and slip-fixed installation method allow it to be seated into a drill jig liner and locked in place without press-fitting, making tool changes faster during multi-operation setups. Compatible with the LS-TW-2 lock screw for secure retention during use.

This bushing is used in tooling jigs and fixtures across metalworking, manufacturing, and machining applications. It is suited for production drilling setups where repeatable hole location accuracy is required. The slip-fixed configuration is common in multi-station jigs where different bushing sizes must be swapped at the same station without disturbing the liner. Machinists, toolmakers, and fixture builders working in job shops or production facilities are the typical end users of this component.

Key Features

• Slip-fixed (SF) installation method for fast, tool-free swapping in renewable bushing liners
• 0.196 inch inside diameter with a tight tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• 3/8 inch body outside diameter and 5/16 inch length under head for standard jig plate fitment
• Steel construction for wear resistance in production drilling applications
• Headed design with 5/8 inch head outside diameter and 1/4 inch head height for positive seating
• Renewable bushing design allows replacement without reworking the jig plate
• Compatible with LS-TW-2 lock screw for positive retention during machining

Compatibility

Designed for use with LS-TW-2 compatible lock screws in standard renewable drill bushing liners. Intended for slip-fixed bushing applications conforming to SF industry standards for drill jig tooling.

Installation Notes

Installation is performed by toolmakers or machinists during jig setup or bushing replacement. The slip-fixed bushing drops into the installed liner and is secured with the compatible LS-TW-2 lock screw — confirm the liner bore matches the 3/8 inch body outside diameter before installation. Remove all cutting tools and de-energize any associated machine before servicing the jig plate or swapping bushings. Do not force the bushing into a liner with an undersized bore, as this can damage the renewable liner or alter hole location accuracy.
