Boneham AM00000986 Slip-fixed Drill Bushing Steel

Product Description

The BONEHAM AM00000986 is a slip-fixed drill bushing designed for precision jig and fixture applications in metalworking and machining environments. It carries industry codes SF and SFM and features a 5.9 mm inside diameter with an inside diameter tolerance of +0.004 to +0.012 mm, ensuring accurate tool guidance during drilling operations. The body outside diameter measures 10 mm and the length under the head is 20 mm. Constructed from steel hardened to 60 to 65 HRC, this bushing delivers the wear resistance required for repeated production use. It is counterbored and renewable, making it a serviceable component in fixed-jig setups. Installation and replacement are handled by machinists and tooling technicians.

This bushing is suited for use in drill jig plates and fixtures where repeatable hole location accuracy is required. The slip-fixed design allows the bushing to be installed into a liner bushing or directly into a jig plate. The renewable construction means the bushing can be replaced without replacing the surrounding fixture, reducing tooling costs over the life of a production run. The LSM-2 compatible lock screw interface secures the bushing in position during operation, preventing rotation under cutting forces.

Key Features

• Inside diameter of 5.9 mm with tolerance of +0.004 to +0.012 mm for precise tool guidance
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Counterbored head with 18 mm head outside diameter and 8 mm head height
• Renewable bushing design supports in-fixture replacement
• Compatible with LSM-2 lock screw for secure retention during drilling
• Meets ANSI standards for drill bushing geometry

Compatibility

Designed for use with LSM-2 lock screws. Compatible with SF and SFM industry-standard slip-fixed bushing applications in drill jig fixtures built to ANSI specifications.

Installation Notes

Installation is performed by a machinist or tooling technician during jig setup or bushing replacement. Power down all associated equipment before servicing any fixture component. Ensure the jig plate bore and mating liner bushing are clean and free of chips before pressing or seating the bushing. Use the LSM-2 lock screw to secure the bushing and verify it does not rotate before returning the fixture to service.
