Boneham P105BB Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P105BB is a press fit headless drill bushing used to guide drill bits with precision in metalworking and machining operations. Classified under Industry Code P, this bushing features a 0.043 inch inside diameter sized for a number 57 wire gauge drill, a 5/32 inch body outside diameter, and a 5/16 inch overall length. The close inside diameter tolerance of plus 0.0001 to plus 0.0004 inches ensures accurate hole placement and repeatable results. Machined from steel, it is designed for permanent installation in jig plates and drill fixtures used by tool and die makers, machinists, and production shop technicians.

This bushing is suited for use in drill jigs and fixture tooling where a permanent, non-renewable guide is required. The headless profile sits flush with the jig plate surface, making it appropriate for applications where a protruding head would interfere with workpiece clearance or fixturing. It is commonly installed in production environments handling light to medium drilling operations on metal workpieces. The press fit installation method locks the bushing in place without fasteners, relying on interference fit with the jig plate bore.

Compatibility

Designed as an OEM-style replacement or new-installation press fit headless drill bushing for use in standard drill jig plates and fixture tooling accepting a 5/32 inch outside diameter press fit bushing bore.

Installation Notes

Installation is performed by machinists or tool and die technicians using a bushing press or arbor press to drive the bushing into a precision-bored jig plate hole. Ensure the receiving bore diameter matches the bushing outside diameter tolerance requirements before pressing to achieve proper interference fit. Do not hammer the bushing in directly without a driver to avoid deforming the bore or bushing. Once pressed in, this bushing is not designed for removal or replacement.
