Boneham SF3222EZ Slip-fixed Drill Bushing 0.161 in Id

Product Description

The BONEHAM SF3222EZ is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling, reaming, and similar machining operations. Built to ANSI standards, this SF-series bushing features a 0.161-inch inside diameter (Wire Size 20) and a 0.5-inch body outside diameter. It is manufactured from steel and hardened to 60 to 65 HRC for long service life under repeated tooling cycles. The head-style design and counterbored body allow secure, positive seating in jig plates. Lock screw compatibility with the LS-1 screw type ensures the bushing stays fixed during production runs. Machining professionals and tool-and-die technicians install this type of bushing in drill jigs and fixtures across manufacturing and metalworking environments.

This bushing is suited for use in production drilling jigs, assembly fixtures, and other precision tooling setups where repeatable hole location is critical. The SF slip-fixed style allows the bushing to be installed into a liner bushing and locked in place with a compatible lock screw, making it appropriate for multi-operation setups where bushing changes between operations are not required. It is a renewable bushing, meaning it can be replaced without replacing the liner.

Key Features

• SF-series slip-fixed style with head for positive seating in jig plates
• 0.161-inch inside diameter with a tight tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Steel construction hardened to 60 to 65 HRC for durability under high-cycle use
• Counterbored body design compatible with standard liner bushings
• LS-1 lock screw compatible to secure bushing in fixed position during operation
• Renewable bushing — replaceable without removing the liner
• Manufactured to ANSI standards

Compatibility

Designed for use with LS-1 compatible lock screws and standard SF-series liner bushings per ANSI specifications. Suitable as an OEM-style or replacement slip-fixed drill bushing in production jig and fixture applications.

Installation Notes

Installation is performed by tooling or machining technicians during jig setup or bushing replacement. Power down and de-energize any associated equipment before servicing a fixture. The bushing should be pressed or slipped into the appropriate liner bushing and secured with a compatible LS-1 lock screw. Do not force an oversized tool through the bushing bore, as this will damage the precision ground inside diameter.
