Boneham AM00000847 Slip-fixed Drill Bushing Sfm

Product Description

The BONEHAM AM00000847 is a slip-fixed drill bushing manufactured to the SFM industry standard. It provides a hardened, precision-bore guide for drill bits and other cutting tools in jig and fixture applications. The bushing features a 2.15 mm inside diameter and an 8 mm body outside diameter, with a 10 mm length under the head. Designed as a renewable component, it can be removed and replaced without disturbing the jig plate, making it well suited for production drilling operations where tooling is regularly cycled or changed. Machinists and toolmakers are the primary installers of this component.

This bushing is used in drill jigs, fixture plates, and tooling blocks where repeatable hole location is required. The slip-fixed design allows the bushing to be installed into a slip-fixed liner bushing already pressed into the jig plate, locking in place during the drilling operation and releasing for removal when the cycle is complete. It is appropriate for light-duty to medium-duty production environments in metalworking, fabrication, and precision machining shops.

Key Features

• SFM industry code slip-fixed design for use with a compatible liner bushing
• 2.15 mm inside diameter provides a close-tolerance guide bore for the cutting tool
• 8 mm body outside diameter for precise fit within the liner bushing
• 10 mm length under the head suits standard jig plate thicknesses
• Renewable bushing construction allows replacement without re-boring the jig plate

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and fixture assemblies requiring an SFM-series slip-fixed liner bushing with an 8 mm body outside diameter.

Installation Notes

Installation is performed by machinists or toolmakers during jig setup or bushing replacement. The slip-fixed bushing is inserted into a compatible liner bushing already installed in the jig plate and locked in position using the head and locking mechanism appropriate to the SFM style. Ensure the jig plate and liner bushing are clean and free of chips or burrs before seating the bushing. Follow applicable shop safety procedures and secure all workholding before beginning drilling operations.
