Boneham AM00001028 Slip-fixed Drill Bushing 7.1mm Id

Product Description

The BONEHAM AM00001028 is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Manufactured from steel hardened to 60 to 65 HRC, this bushing delivers the wear resistance required in high-cycle production jig and fixture applications. The inside diameter measures 7.1 mm with a tolerance of +0.005 to +0.014 mm, ensuring repeatable tool alignment. The body outside diameter is 12 mm and the length under head is 20 mm. The head outside diameter is 22 mm with a head height of 8 mm. The counterbored design and renewable construction allow removal and replacement without disturbing the liner bushing or the jig plate.

This bushing is used in drill jigs and fixture plates across metalworking, machining, and toolmaking applications. It is suited for both production floor environments and toolroom use where consistent hole location is critical. Machinists and toolmakers install slip-fixed bushings in scenarios requiring quick bushing changes between operations, such as drilling followed by reaming through the same jig location. The SF and SFM industry codes indicate compatibility with standard slip-fixed bushing liner systems per ANSI specifications.

Key Features

• Steel construction hardened to 60 to 65 HRC for extended wear life in repetitive drilling operations
• Inside diameter of 7.1 mm with a tight tolerance of +0.005 to +0.014 mm for accurate tool guidance
• Counterbored head design allows flush or recessed seating in jig plates
• Renewable bushing construction permits field replacement without jig plate rework
• Meets ANSI standards; classified under SF and SFM bushing industry codes
• Slip-fixed installation method enables fast bushing swaps between sequential machining operations

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard ANSI slip-fixed liner bushing systems used in drill jigs and fixture tooling.

Installation Notes

Installation is performed by machinists or toolmakers working with drill jig assemblies. Ensure the mating liner bushing and jig plate bore are clean and free of chips or burrs before seating the slip-fixed bushing. The bushing should engage and lock without forcing; do not hammer directly on the head. Follow applicable shop safety procedures and machinery lockout protocols before servicing any fixture mounted to an active machine.
