Boneham AM00000857 Slip-fixed Drill Bushing Sfm 2.3mm Id

Product Description

The BONEHAM AM00000857 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 2.3 mm inside diameter, an 8 mm body outside diameter, and a 10 mm length under the head. It installs by slipping into a liner bushing already fixed in the jig plate, allowing the bushing to be rotated or removed without disturbing the liner. Machinists and toolmakers install these bushings in production and maintenance environments where repeatable hole location accuracy is required.

The AM00000857 is suited for use in drill jigs and fixture plates across light manufacturing, machining, and toolroom applications. The renewable design allows worn bushings to be swapped out without pulling the liner, reducing fixture downtime. Its SFM classification aligns with standard jig bushing specifications widely recognized in industrial tooling practice.

Key Features

• SFM industry code slip-fixed configuration for use with standard liner bushings
• 2.3 mm inside diameter for precise cutting tool guidance
• 8 mm body outside diameter fits compatible liner bushing bores
• 10 mm length under head provides adequate tool guidance depth
• Renewable bushing design allows field replacement without disturbing the liner

Compatibility

Designed as an SFM-standard slip-fixed drill bushing for use with compatible slip-type liner bushings in jig and fixture plate applications. Verify liner bushing inside diameter and head style match before installation.

Installation Notes

A licensed machinist or toolroom technician should install this bushing. Ensure the machine or fixture is powered down and all cutting tools are removed before servicing the jig plate. The bushing is inserted by aligning it with the installed liner bushing and rotating to engage the locking mechanism — no press-fit force is required. Inspect the liner bushing bore for wear or damage before seating the replacement.
