Boneham P405IZ Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P405IZ is a press fit headless drill bushing used to guide drill bits and other cutting tools with precision in jig and fixture applications. With an inside diameter of 0.339 inches and a body outside diameter of 5/8 inches, this bushing provides accurate hole location and repeatable drilling results. The headless design allows flush seating within the jig plate without a protruding flange. Manufactured from steel with a hardness rating of 60 to 65 HRC, the P405IZ resists wear under high-cycle production conditions. The overall bushing length is 5/16 inches. This component is installed permanently using a press fit method and is classified under Bushing Industry Code P.

This drill bushing is suited for use in metalworking, machining, and manufacturing environments where tooling jigs require tight positional tolerances on drilled holes. It is appropriate for production shops, tool rooms, and job shops running moderate to high drill cycles. The 0.339 inch ID corresponds to Letter Size R drill wire sizing, making it compatible with standard tooling in that size range. Machinists, tool and die makers, and fixture builders are the primary installers of this component.

Compatibility

Designed as an OEM-style press fit headless drill bushing for use in machining jigs and fixtures requiring a Letter Size R or 0.339 inch inside diameter tool guide.

Installation Notes

Press fit drill bushings are installed by machinists or tool and die makers using an arbor press or hydraulic press to seat the bushing flush into the jig plate bore. Ensure the receiving bore is machined to the correct interference fit tolerance before pressing. Once installed, this bushing is not designed for removal or replacement. Always verify bushing alignment with the intended drill path before committing the jig to production use.
