Boneham H8822NZ Press Fit Headed Drill Bushing Steel

Product Description

The BONEHAM H8822NZ is a Type H press fit headed drill bushing manufactured from steel. It is designed to guide drill bits and other cutting tools with precision during machining and fabrication operations. The bushing features a 57/64-inch inside diameter and a 1-3/8-inch body outside diameter, with a 1-3/8-inch length under the head. The head outside diameter measures 1-39/64 inches and the head height is 3/8 inch. The press fit installation method holds the bushing securely in a jig plate without the need for a locking mechanism. Machinists, tool and die makers, and manufacturing technicians install this type of bushing in drill jigs and fixtures.

This bushing is suited for production drilling applications where a fixed, non-renewable bushing is preferred. It is installed directly into the drill jig body by pressing into a prepared hole, making it appropriate for high-volume runs where the bushing is not expected to be replaced during the life of the fixture. Typical applications include metalworking shops, fabrication facilities, and machine shops performing repetitive hole-location drilling operations where consistent tool guidance is critical.

Compatibility

Designed as an OEM-style fixed press fit drill bushing for use in standard drill jig plates and fixtures requiring a Type H headed bushing with a 57/64-inch bore.

Installation Notes

This bushing is installed by a machinist or toolmaker using an arbor press or similar pressing equipment into a jig plate hole that has been precision-bored to the appropriate interference fit. Ensure the jig plate hole is clean and free of burrs before pressing the bushing into place. Because this is a non-renewable bushing, removal typically damages the bushing and the jig plate bore, so correct hole preparation before installation is essential. Follow applicable shop safety procedures and machine guarding requirements during installation.
