Boneham H2016EJ Press Fit Headed Drill Bushing Steel

Product Description

The BONEHAM H2016EJ is a Type H press fit headed drill bushing manufactured from steel, designed to guide drill bits with precision in jig and fixture applications. It features a 0.144 inch (No. 27 wire gauge) inside diameter with a tight inside diameter tolerance of +0.0001 to +0.0004 inches, ensuring accurate hole location and repeatable results across production runs. The 5/16 inch body outside diameter and 1 inch length under head make this a compact, rigid insert suited for moderately thick jig plates. Machinists, toolmakers, and fixture builders install this bushing as a permanent, non-renewable guide element pressed directly into a prepared jig plate bore.

This bushing is applied in drilling jigs and fixtures where a headed, press fit style is required for positive axial positioning against the jig plate surface. The head bears against the top face of the plate, preventing the bushing from being driven through under drilling load. It is suitable for production environments where the bushing does not need to be replaced during the life of the fixture. The counterbored design accommodates the head recess where flush or recessed seating is needed.

Key Features

• Type H headed press fit construction for permanent, non-renewable installation
• 0.144 inch (No. 27 wire gauge) inside diameter with +0.0001 to +0.0004 inch tolerance for precise drill guidance
• 5/16 inch body outside diameter and 1 inch length under head
• 27/64 inch head outside diameter and 1/8 inch head height for positive axial location
• Counterbored head seating for flush or recessed installation in jig plates
• Steel construction for durability in repetitive production drilling operations

Compatibility

Designed as a standard Type H press fit headed drill bushing for use in drilling jigs and fixtures requiring a permanent bushing with a headed flange for axial retention.

Installation Notes

Installation is performed by toolmakers or machinist professionals using an arbor press or hydraulic press to drive the bushing into a precision-reamed bore in the jig plate. The bore in the jig plate must be sized to the bushing body outside diameter tolerance to achieve proper press fit interference. Because this is a non-renewable bushing, it is intended as a permanent installation and is not designed for routine field removal or replacement. Power down any associated machine tooling before performing jig maintenance or bushing installation.
