Boneham SF205FP Slip-fixed Drill Bushing 0.182 in Id Steel

Product Description

The BONEHAM SF205FP is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. It features an inside diameter of 0.182 inches (wire size 14) with a tight tolerance of +0.0001 to +0.0004 inches, ensuring accurate tool guidance and repeatable hole location. The body outside diameter measures 0.3125 inches (5/16 inches) with a length under head of 5/16 inches. Constructed from hardened steel at 60 to 65 HRC, this bushing delivers wear resistance suited to production drilling environments. A head-type design with a head outside diameter of 35/64 inches and head height of 1/4 inch retains the bushing securely in the jig plate. Lock screw compatibility is LS-1. Installation technicians, tool-and-die makers, and fixture builders specify this component for precision metalworking operations.

The SF205FP is intended for use in drill jigs and machining fixtures where a renewable, slip-fixed bushing is required. The renewable design allows the bushing to be replaced without disturbing the jig plate, making it practical for high-cycle production runs where wear is expected. The SF industry code designates the slip-fixed style, which installs into a liner bushing and locks in place with an LS-1 compatible lock screw. This configuration suits repetitive drilling, reaming, and light boring operations in both job-shop and production-line settings where hole-location accuracy is critical.

Key Features

• Slip-fixed (SF) bushing style with LS-1 compatible lock screw for secure seating in liner bushings
• Inside diameter of 0.182 inches (wire size 14) with tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Hardened steel construction at 60 to 65 HRC for high wear resistance in production drilling
• Renewable bushing design allows field replacement without reworking the jig plate
• Head-type configuration with 35/64-inch head OD and 1/4-inch head height for positive retention
• Meets ANSI standards for drill bushing dimensions and interchangeability

Compatibility

Designed as an ANSI-standard slip-fixed drill bushing compatible with LS-1 lock screws and standard liner bushings of matching body outside diameter. Confirm liner bushing bore dimensions match the 0.3125-inch body OD before installation.

Installation Notes

Installation is performed by toolmakers or fixture technicians during jig assembly or bushing replacement. The jig plate must be secured and the liner bushing must be properly seated before inserting the SF205FP. Use the correct LS-1 lock screw to lock the bushing in position and prevent rotation during drilling. Inspect the bushing bore and seating surface for burrs or contamination before installation to maintain dimensional accuracy.
