Boneham AM00000925 Slip-fixed Bushing Sfm 4.25 Mm Id

Product Description

The BONEHAM AM00000925 is a slip-fixed drill bushing manufactured to the SFM industry standard. It is designed to guide cutting tools such as drill bits during precision machining and fabrication operations, maintaining accurate hole location and reducing tool drift. The bushing features a 4.25 mm inside diameter, a 10 mm body outside diameter, and a 25 mm length under the head. It is a renewable bushing, meaning it can be removed and replaced independently of the liner bushing, making it well suited for jig tooling setups that require periodic replacement due to wear.

This slip-fixed bushing is used in drill jig applications across industrial manufacturing, metal fabrication, and machine shop environments. The SFM configuration combines elements of a slip bushing and a fixed bushing, locking in place during drilling while still allowing removal for tool changes or replacement. It is installed by machinists and tooling technicians working with precision drill jigs where repeatable hole accuracy is required across production runs.

Key Features

• SFM industry code - slip-fixed design locks during drilling and allows controlled removal
• 4.25 mm inside diameter for precise drill bit guidance
• 10 mm body outside diameter for standard liner bushing seating
• 25 mm length under head provides depth guidance in thicker jig plates
• Renewable bushing construction supports replacement without disturbing the jig fixture

Compatibility

Designed as an OEM-style replacement or tooling component for drill jig fixtures requiring SFM-standard slip-fixed renewable bushings with a 4.25 mm inside diameter and 10 mm body outside diameter.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the corresponding liner bushing and jig plate bore are clean and free of burrs before inserting the slip-fixed bushing. The bushing should be seated fully and oriented so the locking feature engages correctly before any drilling operation begins. Follow the tooling fixture manufacturer guidelines for proper seating depth and replacement intervals.
