Boneham AM00000898 Slip-fixed Drill Bushing Steel

Product Description

The BONEHAM AM00000898 is a slip-fixed drill bushing designed to guide cutting tools accurately in jig and fixture applications. It installs into a liner bushing and is secured in place with a lock screw, preventing rotation during machining operations. The bushing features a 3.25 mm inside diameter with a tolerance of +0.004 to +0.012 mm, a body outside diameter of 8 mm, and a length under the head of 10 mm. Constructed from steel hardened to 60 to 65 HRC, it delivers consistent tool guidance and resists wear in high-cycle production environments. Machinists, toolmakers, and fixture builders are the primary users.

This bushing is suited for use in drill jigs, modular fixturing systems, and precision machining setups where repeatable hole location is required. The slip-fixed design allows the bushing to be removed and reinstalled without disturbing the liner, making it practical for applications that require multiple tooling operations in the same hole location. It conforms to ANSI standards and is compatible with the LSM-1 lock screw. Typical applications include production drilling, reaming, and boring in both job shop and manufacturing environments.

Key Features

• Slip-fixed installation method allows removal and reinstallation without liner disturbance
• 3.25 mm inside diameter with tight tolerance of +0.004 to +0.012 mm for accurate tool guidance
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Counterbored head design accommodates lock screw seating
• Compatible with LSM-1 lock screw for positive rotational retention
• Meets ANSI standards for drill bushing dimensions and performance

Compatibility

Compatible with LSM-1 lock screws. Conforms to SF and SFM industry bushing codes per ANSI standards. Designed for use with standard liner bushings in drill jig applications.

Installation Notes

Installation is performed by toolmakers or machinists during fixture assembly or tooling changeover. The bushing slips into a pressed liner bushing and is locked in position using an LSM-1 lock screw. Ensure the liner bushing bore and the mating surfaces are clean and free of chips before installation. Do not force the bushing into a liner with an incompatible bore diameter.
