Boneham H264GF Press Fit Headed Drill Bushing Steel

Product Description

The BONEHAM H264GF is a Type H press fit headed drill bushing manufactured from steel, designed to guide drill bits with precision in jig and fixture applications. With an inside diameter of 0.204 inches and a body outside diameter of 13/32 inches, this bushing is pressed directly into a drill jig plate without requiring a locking mechanism. The head outside diameter is 1/2 inch with a head height of 5/32 inches and a length under head of 1/4 inches. It is a non-renewable, non-counterbored design intended for permanent installation in production and prototype drilling operations.

This bushing is suited for use in drill jigs where a fixed, permanent guide is required for repetitive hole drilling operations. The pressed fit installation makes it appropriate for medium to high-volume production environments where the bushing does not need to be removed between operations. Machinists, tool and die makers, and fixture builders typically install this component. The inside diameter tolerance of +0.0001 to +0.0004 inches ensures consistent hole location and drill alignment across multiple workpieces.

Key Features

• Type H press fit design for permanent, no-lock installation in drill jigs
• Steel construction for durability in production drilling environments
• Inside diameter of 0.204 inches with a close tolerance of +0.0001 to +0.0004 inches
• Head outside diameter of 1/2 inch seats flush against jig plate surface to control depth positioning
• Non-renewable, non-counterbored design for straightforward, single-use fixture installation
• Conforms to standard bushing industry code H for interchangeability in jig design

Compatibility

Designed as an OEM-style replacement or direct installation component for standard drill jig fixtures requiring a Type H press fit headed bushing with a 0.204 inch inside diameter and 13/32 inch body outside diameter.

Installation Notes

Installation is performed by machinists or tool and die professionals using an arbor press to seat the bushing into a properly sized jig plate hole. The jig plate hole must be machined to the correct interference fit tolerance before pressing the bushing in place. Remove all chips and debris from the mounting hole prior to installation to prevent misalignment. Once pressed in, this bushing is not intended to be removed or replaced without reworking the fixture.
