Boneham AM00000840 Slip-fixed Drill Bushing 19.5mm Id

Product Description

The BONEHAM AM00000840 is a slip-fixed renewable drill bushing designed for precision hole-location applications in jig and fixture work. It features a 19.5 mm inside diameter with a tolerance of +0.007 to +0.020 mm, a 30 mm body outside diameter, and a 46 mm head outside diameter. Constructed from steel hardened to 60-65 HRC, this bushing delivers the wear resistance and dimensional stability required in high-cycle production environments. The counterbored head design allows it to seat flush or recessed within a jig plate, and its renewable construction means it can be replaced without retooling the fixture.

Slip-fixed bushings of this type are used in metalworking, machining, and fabrication shops where drill jigs must maintain repeatable hole placement across large production runs. The SF and SFM industry codes indicate compatibility with standard jig bushing liner systems. This bushing is appropriate for use in fixed or rotating applications where the bushing does not need to rotate with the cutting tool, making it well suited to drilling, reaming, and similar operations performed by machinists and toolmakers in production and toolroom settings.

Key Features

• Steel construction hardened to 60-65 HRC for long service life in high-cycle drilling applications
• 19.5 mm inside diameter with a close tolerance of +0.007 to +0.020 mm for precise hole location
• 30 mm body outside diameter and 46 mm head outside diameter with a 10 mm head height
• 45 mm length under head provides adequate tool guidance depth for standard jig plate thicknesses
• Counterbored head allows flush or recessed mounting in jig plates
• Renewable bushing design enables field replacement without reworking the liner or fixture
• Meets ANSI standards for drill bushing dimensions and tolerances

Compatibility

Designed as an OEM-style replacement or direct-fit bushing for standard SF and SFM industry-code jig bushing liner systems conforming to ANSI specifications.

Installation Notes

Installation is performed by machinists or toolmakers using standard jig bushing press or slip-fit procedures. Ensure the liner bore and mating surfaces are clean and free of burrs before seating the bushing. Verify that the bushing rotates freely or locks as intended for the application before committing the fixture to production. Follow applicable shop safety procedures when pressing components into hardened tooling plates.
