Boneham SFT366IO Slip-fixed Drill Bushing 0.316 in Id Steel

Product Description

The BONEHAM SFT366IO is a slip-fixed drill bushing conforming to SF industry standards, designed to guide cutting tools with precision in jig and fixture applications. It features a 0.316 inch inside diameter with a close tolerance of +0.0001 to +0.0005 inches, a 9/16 inch body outside diameter, and a 3/8 inch length under the head. Constructed from steel, this headed bushing is renewable and locks in place using an LS-TW-2 compatible lock screw. Machinists, toolmakers, and fixture builders rely on this type of bushing to maintain accurate hole location and reduce drill wander across repeated production cycles.

The SFT366IO is suited for use in drill jigs and production fixtures where the bushing must be held firmly against rotation and axial movement during machining operations. The headed design seats against the jig plate surface, providing a positive stop and consistent tool guidance depth. Its renewable design allows replacement without scrapping the jig body, making it practical for high-cycle production environments. This bushing is a direct fit where SF-type slip-fixed bushings with a 0.316 inch bore and 9/16 inch body are specified.

Compatibility

Designed as an SF-type slip-fixed renewable drill bushing for use in drill jigs and fixtures requiring a 0.316 inch bore guide with a 9/16 inch body. Compatible with LS-TW-2 lock screws as specified by the manufacturer.

Installation Notes

Installation is typically performed by toolmakers or machinist-level trades during jig setup or bushing replacement. The mating jig plate bore must be machined to the appropriate press-fit tolerance for the 9/16 inch body before the bushing is seated. The LS-TW-2 lock screw must be properly engaged to prevent rotation or withdrawal during cutting operations. Ensure all tooling and workholding components are secured and the machine is de-energized before servicing jig fixtures.
