Boneham CB00001166 Press Fit Headed Drill Bushing

Product Description

The BONEHAM CB00001166 is a Type H press fit headed drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. The bushing features a 5/16 inch (0.3125 inch) inside diameter and a 1/2 inch body outside diameter, with a 1 inch length under the head. Constructed from steel and hardened to 60 to 65 HRC, it delivers the wear resistance required for repeated production use. The inside diameter tolerance of +0.0001 to +0.0005 inch ensures consistent tool guidance and tight positional accuracy across high-cycle jig and fixture applications.

This bushing is used in drill jigs and fixtures across machining, fabrication, and toolmaking environments. The headed design allows the bushing to seat flush against the jig plate and resist axial push-through under drilling loads. It is installed permanently via press fit into a prepared jig plate bore and is not designed for field removal or renewal. Typical end users include tool and die makers, machinist shops, and production maintenance personnel working with drill jigs in metalworking applications.

Key Features

• Type H industry-standard bushing code for consistent cross-vendor jig compatibility
• 5/16 inch inside diameter with +0.0001 to +0.0005 inch tolerance for precise tool guidance
• Hardened steel construction at 60 to 65 HRC for long service life in high-cycle drilling
• 1 inch length under head provides solid tool support through thicker jig plates
• Head outside diameter of 39/64 inch and head height of 7/32 inch for positive seating
• Press fit installation method for permanent, vibration-resistant mounting

Compatibility

Designed as an OEM-style replacement or original-equipment press fit headed drill bushing for standard drill jigs and fixtures conforming to ANSI bushing specifications.

Installation Notes

Installation is performed by machinists or tool and die professionals using an arbor press or hydraulic press to seat the bushing into a properly sized jig plate bore. The receiving bore must be machined to the correct interference fit tolerance per ANSI standards before pressing the bushing into place. Power down all associated machinery before working on any jig or fixture. Once pressed in, this bushing is not renewable and should not be driven out and reused.
