Boneham AM00001029 Slip-fixed Drill Bushing Sfm

Product Description

The BONEHAM AM00001029 is a slip-fixed drill bushing manufactured to SFM industry standards. It is used in jig and fixture tooling to guide drill bits, reamers, and other cutting tools with precision during machining and fabrication operations. The bushing features a 7.1 mm inside diameter, a 12 mm body outside diameter, and a 25 mm length under the head. It installs into a fixed liner bushing already seated in the jig plate, allowing quick tool changes without disturbing the liner. Machinists, tool-and-die makers, and fabrication professionals rely on this style of renewable bushing to maintain hole-location accuracy across production runs.

This bushing is suited for use in drill jigs and production fixtures where tool guidance repeatability is critical. The slip-fixed design means the bushing is held in place by a lock during drilling and can be removed by rotating and lifting when the operation is complete. It is appropriate for moderate- to high-volume drilling and reaming setups in metalworking, aerospace fabrication, and general manufacturing environments where fixture tooling is common practice.

Key Features

• SFM industry code - conforms to recognized slip-fixed bushing standards for interchangeability
• 7.1 mm inside diameter guides the cutting tool with close tolerances
• 12 mm body outside diameter seats into a standard SFM-compatible liner bushing
• 25 mm length under head provides full cutting-zone support through the jig plate
• Renewable design - bushing can be replaced without removing the liner, reducing fixture downtime

Compatibility

Designed as an OEM-style replacement or direct fit for fixtures using SFM-series slip-fixed drill bushings with a 12 mm body outside diameter and 7.1 mm inside diameter liner configuration.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the mating liner bushing is clean and free of chips before inserting the slip-fixed bushing. Secure the bushing with the appropriate locking mechanism before beginning any drilling or reaming operation. Do not use the bushing as a press-fit component - it is designed for slip-fit engagement with a liner only.
