Boneham AM00000878 Slip-fixed Drill Bushing 2.9mm Id 8mm Od

Product Description

The BONEHAM AM00000878 is a slip-fixed drill bushing designed for precision hole-location applications in jig and fixture work. Built to SF and SFM industry codes, it features a 2.9 mm inside diameter with a tight tolerance of +0.002 to +0.008 mm, a body outside diameter of 8 mm, and a length under head of 16 mm. The bushing is machined from steel and hardened to 60 to 65 HRC, delivering the wear resistance required for repetitive drilling operations. It is counterbored to accept an LSM-1 lock screw, keeping the bushing securely seated during use. Installation and removal are quick, making it well-suited for renewable bushing applications where liners are already in place.

This bushing is used in precision drilling, reaming, and boring fixtures across metalworking, tooling, and machining environments. The slip-fixed design allows the bushing to be inserted and locked without press-fit tooling, making it a practical choice for production jigs that require periodic bushing changes. The renewable design means the bushing can be swapped out as it wears without disturbing the jig plate or liner. This part is appropriate for toolroom technicians, machine operators, and fixture builders working to ANSI standards.

Key Features

• Slip-fixed installation method for fast, tooling-free insertion and removal
• Inside diameter of 2.9 mm with a tolerance of +0.002 to +0.008 mm for accurate hole location
• Steel construction hardened to 60 to 65 HRC for long service life
• Counterbored head accepts LSM-1 lock screw to prevent rotation and axial movement
• Renewable bushing design compatible with standard drill bushing liners
• Meets ANSI standards for jig bushing dimensions and tolerances

Compatibility

Designed for use with LSM-1 compatible lock screws and standard renewable liner bushings. Conforms to SF and SFM bushing industry codes per ANSI standards. Verify liner inside diameter and head counterbore dimensions before installation.

Installation Notes

This bushing is installed by toolroom machinists and fixture builders familiar with jig and drill fixture assembly. Ensure the mating liner bushing is clean and free of chips or burrs before inserting the slip-fixed bushing. Secure the bushing with an LSM-1 lock screw to prevent movement during drilling operations. Follow all applicable shop safety procedures and de-energize any associated CNC or drilling equipment before performing fixture maintenance.
