Boneham SF325EN Slip-fixed Drill Bushing 0.1495 in Id

Product Description

The BONEHAM SF325EN is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. It features a 0.1495 inch inside diameter (wire size No. 25), a 1/2 inch body outside diameter, and a 5/16 inch length under the head. Constructed from steel, this bushing provides reliable wear resistance in production drilling setups. The head style with a 51/64 inch head outside diameter and 1/4 inch head height seats securely in the jig plate, while renewable design allows replacement without replacing the entire fixture. Compatible with LS-1 lock screws for positive retention during operation. Installed by machinists, toolmakers, and precision fixture builders in metalworking and manufacturing environments.

Slip-fixed bushings in the SF industry code series are used in drill jigs where the bushing must be locked in place during the drilling operation but can be removed and replaced when worn. This makes them well suited for production runs requiring repeatable hole location accuracy. The SF325EN fits standard jig plate bores and works with coordinating liner bushings in typical two-bushing setups. It is appropriate for both light and moderate production drilling, reaming, and similar guided-tool operations where hole position tolerance is critical.

Key Features

• Non-counterbored body; 5/16 inch length under head suits standard plate thicknesses

Compatibility

Designed as an OEM-style slip-fixed drill bushing conforming to SF industry code standards, compatible with LS-1 lock screws and standard liner bushing setups used in drill jig and fixture applications.

Installation Notes

Installation is typically performed by machinists or toolmakers during jig assembly or bushing replacement. Press the bushing into the liner or jig plate bore by hand or with a bushing press; do not hammer directly on the head face. Secure with an LS-1 compatible lock screw after seating. Always verify inside diameter clearance against the tool shank diameter before installation to ensure proper fit and avoid tool binding.
