Boneham AM00000933 Slip-fixed Bushing Sfm 4.4mm Id

Product Description

The BONEHAM AM00000933 is a slip-fixed drill bushing conforming to the SFM industry code standard. It is designed to guide cutting tools accurately during drilling, reaming, or boring operations in jig and fixture applications. The bushing features a 4.4 mm inside diameter, a 10 mm body outside diameter, and a 20 mm length under the head. The slip-fixed design allows the bushing to be installed and removed without pressing, making it well suited for applications that require tool changes or bushing replacement during a production run. Machinists, toolmakers, and fixture builders are the primary installers of this component.

This bushing is used in drill jigs and machining fixtures across manufacturing and metalworking environments. The renewable design means the bushing can be replaced independently of the liner bushing pressed into the jig plate, reducing downtime and tooling cost. Typical applications include multi-operation fixtures where different cutting tool diameters are used at the same hole location. The SFM designation identifies the head style and retention method, allowing direct cross-reference to other SFM-coded bushings in standard tooling catalogs.

Key Features

• SFM industry code slip-fixed configuration for tool-free installation and removal
• 4.4 mm inside diameter for precise cutting tool guidance
• 10 mm body outside diameter for use with corresponding liner bushings
• 20 mm length under head provides stable tool guidance depth
• Renewable bushing construction supports in-fixture replacement without jig plate rework

Compatibility

Designed as an OEM-style replacement or standard-fit slip-fixed drill bushing for use with SFM-coded liner bushings installed in drill jig plates and machining fixtures.

Installation Notes

Installation of slip-fixed bushings is performed by toolmakers or machinists during fixture setup or bushing replacement. The bushing is seated into a mating liner bushing by hand or with light tool pressure and is retained by a locking mechanism rather than a press fit. Always ensure the liner bushing bore and the slip-fixed bushing body are clean and free of chips or burrs before seating. Follow applicable shop safety procedures and de-energize or secure any machine tool before servicing fixtures.
