Boneham AM00000821 Slip-fixed Drill Bushing 16.5mm Id

Product Description

The BONEHAM AM00000821 is a slip-fixed drill bushing designed to guide cutting tools accurately during drilling, reaming, and boring operations in jig and fixture applications. Built to SF and SFM industry standards, it features a 16.5 mm inside diameter with a close tolerance of +0.006 to +0.017 mm, a 26 mm body outside diameter, and a 20 mm length under the head. The bushing is machined from steel and hardened to 60 to 65 HRC for wear resistance and dimensional stability under repeated use. It is counterbored and renewable, making it suitable for high-volume production environments where bushings require periodic replacement without retooling the fixture.

This bushing is used in precision drilling jigs and fixtures in manufacturing, tooling, and machining environments. The slip-fixed design allows the bushing to be installed and removed by hand or with standard tooling while remaining positively located during the cutting operation. It is a fit for production machine shops, tool and die operations, and maintenance facilities that maintain drill jig assemblies. The renewable construction reduces fixture downtime by allowing worn bushings to be swapped without replacing the entire jig plate.

Key Features

• SF and SFM industry code compliance for standardized fitment in drill jigs
• 16.5 mm inside diameter with precision tolerance of +0.006 to +0.017 mm
• Steel construction hardened to 60 to 65 HRC for long service life
• Counterbored design supports proper seating and tool clearance
• Renewable bushing construction allows replacement without fixture modification
• Conforms to ANSI standards

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and fixtures requiring an SF or SFM style slip-fixed renewable bushing with a 16.5 mm inside diameter and 26 mm body outside diameter per ANSI standards.

Installation Notes

Installation and replacement should be performed by a qualified tooling technician or machinist. Ensure the jig plate is secured and all cutting equipment is powered down before removing or installing the bushing. Use appropriate press or hand tools to seat the bushing fully; do not strike the head directly with a hammer. Verify inside diameter clearance and alignment with the drill or reamer before resuming production.
