Boneham AM00000788 Slip-fixed Drill Bushing 11.8mm Id

Product Description

The BONEHAM AM00000788 is a slip-fixed drill bushing designed for use in jig and fixture tooling applications. Built to industry code SF and SFM, this bushing features an 11.8 mm inside diameter, an 18 mm body outside diameter, and a 16 mm length under head. Constructed from steel and hardened to 60 to 65 HRC, it delivers the wear resistance and dimensional stability required in production drilling operations. The counterbored head design allows secure seating in a liner bushing without additional fasteners. Licensed trades and tooling specialists install this component as a renewable element in drill jig assemblies.

This bushing is suited for metal fabrication shops, machine shops, and manufacturing facilities where repeatable hole location accuracy is critical. The slip-fixed installation method allows the bushing to be removed and replaced without disturbing the jig body, making it well-suited for operations that require tool changes between drilling and reaming operations on the same fixture. The inside diameter tolerance of plus 0.006 to plus 0.017 mm ensures consistent guidance for twist drills and reamers within that size range.

Key Features

• Slip-fixed installation method for tool-change flexibility without jig disassembly
• Steel construction hardened to 60 to 65 HRC for extended service life under high-cycle drilling
• Counterbored head seats flush in a liner bushing for positive axial location
• Renewable design allows field replacement without replacing the jig plate or liner
• Inside diameter tolerance of plus 0.006 to plus 0.017 mm for precise drill guidance
• Meets ANSI standards for drill bushing geometry and dimensional requirements

Compatibility

Designed as an OEM-style replacement or production component for ANSI-standard slip-fixed drill jig assemblies using SF and SFM industry-code liner bushings with an 18 mm body outside diameter bore.

Installation Notes

Installation is performed by tooling technicians or machinists during jig setup or bushing replacement. Ensure the liner bushing bore is clean and free of chips before inserting the slip-fixed bushing. The bushing should seat fully against the jig plate surface with no rocking or lateral play before clamping. Do not force the bushing into an undersized bore; verify liner bushing inside diameter matches the 18 mm body outside diameter of this part before installation.
