Boneham H1622DA Press Fit Headed Drill Bushing

Product Description

The BONEHAM H1622DA is a Type H press fit headed drill bushing used to guide drill bits and cutting tools with precision in jig and fixture applications. Machined from steel, this bushing features a 0.0995 inch inside diameter with a tight inside diameter tolerance of +0.0001 to +0.0004 inches, ensuring accurate and repeatable hole placement. The 1/4 inch body outside diameter and 1-3/8 inch length under head make it well suited for through-plate installations where consistent drill guidance is required. Machinists, tool and die makers, and precision fabricators install this type of bushing when setting up production drilling operations.

Type H press fit headed drill bushings are used in drill jigs and fixture plates across metal fabrication, aerospace, automotive, and general manufacturing environments. The headed design seats against the top face of the jig plate, providing a positive stop and preventing the bushing from being pushed through under drilling load. The counterbored feature accommodates the head for flush or recessed seating where plate clearance is required. This bushing is intended for permanent installation and is not designed to be renewable or interchangeable during a production run.

Key Features

• Type H press fit installation for permanent, fixed positioning in jig plates
• Inside diameter of 0.0995 inches corresponding to wire gauge size 39
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise drill guidance
• Steel construction for durability in repetitive drilling operations
• Headed design with 23/64 inch head outside diameter provides positive axial stop
• Counterbored for flush or recessed head seating in the fixture plate

Compatibility

Designed as an OEM-style replacement or direct-install component for drill jig fixtures requiring a Type H press fit headed bushing with a 0.0995 inch inside diameter and 1/4 inch body outside diameter.

Installation Notes

Installation is performed by machinists or tool and die makers using a press or arbor press to seat the bushing into a pre-reamed jig plate hole. Power down all associated machinery before working on the fixture plate. The bushing should be pressed squarely and fully into the plate to ensure the head seats flush or as specified by the fixture design. Once pressed in, this bushing is not intended for removal or reuse.
