Boneham SF328EU Slip-fixed Drill Bushing 5/32 in Id

Product Description

The BONEHAM SF328EU is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Built to ANSI standards, this bushing features a 5/32 inch inside diameter and a 1/2 inch body outside diameter, with a length under head of 1/2 inch. Constructed from hardened steel with a surface hardness of 60 to 65 HRC, it delivers consistent bore accuracy and resists wear under repeated tool cycling. The headed design and renewable construction make it well-suited for jig plate applications where bushings require periodic replacement without reworking the fixture.

This slip-fixed bushing is used in drill jig fixtures across manufacturing, tooling, and machining environments. The SF industry code designates it as a headed, slip-fit renewable bushing retained by a lock screw rather than a press fit, allowing field replacement without pressing out the liner. Typical applications include production drilling jigs in metal fabrication shops, toolrooms, and maintenance repair operations where repeatable hole location is required. Machinists and toolmakers are the primary installers of this component.

Key Features

• 5/32 inch inside diameter with a tight tolerance of +0.0001 to +0.0004 inches for accurate tool guidance
• Hardened steel construction at 60 to 65 HRC for long service life under high-cycle drilling
• Renewable design allows bushing replacement without disturbing the jig plate or liner
• Compatible with LS-1 lock screw for secure retention in the jig fixture
• Headed (not headless) profile seats flush against the jig plate surface
• Meets ANSI standards for slip-fixed bushing geometry and dimensional accuracy

Compatibility

Designed as an ANSI SF-series slip-fixed renewable drill bushing compatible with LS-1 lock screws and standard drill jig liners sized for a 1/2 inch body outside diameter.

Installation Notes

Installation is typically performed by a machinist or toolmaker during jig setup or bushing replacement. Before servicing the jig plate, secure the workpiece fixture and ensure all drilling equipment is powered down and de-energized. The LS-1 lock screw must be properly engaged to prevent rotation or pullout during tool operation. Do not force or hammer the bushing into position, as damage to the bore tolerance or head seating surface may compromise hole location accuracy.
