Boneham H5622LR Press Fit Headed Drill Bushing

Product Description

The BONEHAM H5622LR is a Type H press fit headed drill bushing designed to guide drill bits and other cutting tools with precision in jig and fixture applications. Manufactured from hardened steel with a surface hardness of 60 to 65 HRC, this bushing resists wear under repeated drilling cycles. The inside diameter is 17/32 inches with a tight tolerance of +0.0001 to +0.0005 inches, ensuring consistent hole location accuracy. A head diameter of 1-7/64 inches and a head height of 1/4 inch keep the bushing seated firmly against the jig plate. Machinists, tool and die makers, and production fixture builders install this type of bushing in drill jigs where permanent, non-renewable guidance is required.

The H5622LR is suited for production drilling operations in metalworking and fabrication environments where a fixed, press-fit installation is specified. The headed design seats flush against the surface of a drill jig plate, preventing the bushing from being pushed through under axial load. With a body outside diameter of 7/8 inches and a length under head of 1-3/8 inches, this bushing fits standard jig plate thicknesses common in both short-run and high-volume production setups. It is not renewable and is intended as a permanent installation in the jig body.

Key Features

• Press fit installation method for permanent, non-renewable jig plate seating
• Type H headed design resists axial push-through under drilling load
• Inside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• Hardened steel construction at 60 to 65 HRC for extended wear life
• Meets ANSI standards for drill bushing dimensions and performance

Compatibility

Designed as an OEM-style press fit headed drill bushing conforming to ANSI standards, suitable for use in standard drill jigs and fixtures requiring a Type H headed bushing with a 17/32 inch inside diameter and 7/8 inch body outside diameter.

Installation Notes

Press fit bushings are installed by machinists or tool and die makers using an arbor press or hydraulic press. The receiving hole in the jig plate must be finish-reamed to the correct interference fit specification before installation. Power down all associated machinery and secure the jig fixture before pressing the bushing into place. Do not use impact tools to drive the bushing, as this can damage the bore or alter alignment.
