Boneham SF3212FX Slip-fixed Drill Bushing 0.1935 in Id

Product Description

The BONEHAM SF3212FX is a slip-fixed drill bushing designed to guide cutting tools accurately through jig plates in production and tooling applications. It features a 0.1935-inch inside diameter sized for a No. 10 wire gauge drill, a 0.5-inch body outside diameter, and a 3/4-inch length under head. Constructed from steel and hardened to 60 to 65 HRC, the SF3212FX provides wear-resistant performance in repetitive drilling operations. The headed design seats firmly in the jig body, and the renewable construction allows replacement without replacing the entire fixture. Installation is compatible with the LS-1 lock screw standard.

Slip-fixed bushings like the SF3212FX are used in drill jigs and fixtures across manufacturing, fabrication, and precision machining environments. The SF industry code designates a headed, slip-in style that locks in place with a set screw, making it suitable for operations where the bushing must remain stationary during drilling. This part is a practical choice for tool rooms and production shops running repetitive hole patterns that demand consistent location accuracy.

Compatibility

Compatible with LS-1 lock screws. Designed as a renewable slip-fixed bushing per ANSI standards for use in drill jig fixtures accepting a 1/2-inch body outside diameter bushing.

Installation Notes

Slip-fixed bushings are installed and serviced by tool and die makers, machinists, or maintenance technicians working with jig and fixture systems. Ensure the jig plate counterbore is clean and dimensionally correct before inserting the bushing. Secure the bushing with the appropriate LS-1 lock screw and verify there is no axial movement before running production. Do not force the bushing into an undersized bore, as this can distort the inside diameter and compromise tool guidance accuracy.
