Boneham SF206FP Slip-fixed Drill Bushing 0.182 in Id Steel

Product Description

The BONEHAM SF206FP is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. It features a 0.182 inch inside diameter sized for a number 14 wire gauge drill, a 5/16 inch body outside diameter, and a 3/8 inch length under head. Manufactured from steel, the SF206FP provides the hardness and wear resistance required for repeated tool passes in jig plate applications. The head-type design seats firmly against the jig plate face, and the renewable bushing construction allows replacement without disturbing the press-fit liner. This part is installed by machinists, toolmakers, and precision drilling technicians in production and maintenance environments.

The SF206FP is used in drill jig applications where accurate hole location must be maintained across repeated operations. It fits into a corresponding liner bushing already pressed into the jig plate, then locks in place using an LS-1 compatible lock screw. Typical scenarios include production-line drilling fixtures in light manufacturing, maintenance shops, and tool-and-die operations where controlled hole positioning is critical. It is suited for both ferrous and non-ferrous workpiece materials where a guided cutting tool is required.

Key Features

• 0.182 inch inside diameter for number 14 wire gauge drill tools
• 5/16 inch body outside diameter with 3/8 inch length under head
• Head outside diameter of 35/64 inch and head height of 1/4 inch for positive seating against jig plate
• Steel construction provides wear resistance for repeated tool passes
• Renewable bushing design allows field replacement without disturbing the pressed liner
• Compatible with LS-1 lock screw for secure, tool-free retention
• Inside diameter tolerance of plus 0.0001 to plus 0.0004 inches for consistent tool guidance

Compatibility

Designed for use with LS-1 compatible lock screws and standard SF-series drill jig liner bushings. Follows the SF industry bushing code for slip-fixed head-type renewable bushings.

Installation Notes

Installation is performed by machinists or toolmakers. Ensure the corresponding liner bushing is fully pressed and seated in the jig plate before inserting the SF206FP. Secure the bushing using an LS-1 lock screw torqued to the fixture specification. Inspect the inside diameter for chips or scoring after extended use and replace the bushing if wear exceeds the specified tolerance band.
