Boneham SFT166DO Slip-fixed Drill Bushing 0.113 in Id

Product Description

The BONEHAM SFT166DO is a slip-fixed drill bushing designed to guide cutting tools accurately during drilling, reaming, and boring operations. Built to industry code SF, this bushing features a 0.113 inch inside diameter and a 1/4 inch body outside diameter, making it suited for close-tolerance tooling applications in jig and fixture work. Constructed from steel, it delivers the durability and wear resistance that production environments demand. The head-style design with a 7/16 inch head outside diameter seats firmly in the jig plate, and the part is classified as a renewable bushing, allowing straightforward field replacement without retooling the fixture.

This bushing is appropriate for use in drill jigs and machining fixtures across manufacturing, maintenance, and toolroom settings. It is installed wherever repeatable hole location accuracy is required, such as in assembly jigs for structural, mechanical, or sheet-metal work. The 3/8 inch length under head accommodates standard jig plate thicknesses common in light-to-medium duty tooling. It is compatible with the LS-TW-2 lock screw, which secures the bushing in the liner and prevents rotation during cutting operations.

Key Features

• Slip-fixed SF bushing design allows quick tool changes while maintaining location accuracy

Compatibility

Designed for use with the LS-TW-2 lock screw. Fits standard drill jig liner bushings that accept SF-series slip-fixed bushings with a 1/4 inch body outside diameter.

Installation Notes

Drill bushings are typically installed by toolmakers or machinists using press-fit or slip-fit procedures appropriate to the bushing series. Ensure the mating liner bushing and jig plate bore are clean and free of burrs before installation. The lock screw must be properly engaged to prevent bushing rotation during cutting. Follow applicable shop safety and machine guarding procedures when working with drill jigs and cutting tools.
