Boneham PT364IH Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT364IH is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in jig and fixture applications. Carrying industry code P, this bushing features an inside diameter of 0.302 inches with a tight tolerance of +0.0001 to +0.0005 inches, ensuring accurate hole location and repeatable drilling performance. The outside diameter measures 9/16 inches and the overall length is 1/4 inch. Constructed from steel, the PT364IH is a non-renewable, headless design intended for permanent installation in drill jigs. Machinists, tool and die makers, and fixture builders are the primary installers of this component.

This bushing is suited for use in production drilling fixtures where a flush, headless profile is required. The press fit installation method means the bushing is driven directly into a precisely reamed hole in the jig body, providing a secure, low-profile fit. It is appropriate for light to medium production environments where hole location accuracy is critical and bushing replacement is not anticipated. The P industry code designation identifies the inside diameter size within the standard drill bushing series used across tooling and metrology applications.

Installation Notes

Installation is performed by machinists or toolmakers using a press or arbor press to drive the bushing into a reamed hole sized to accept the 9/16 inches outside diameter. The receiving hole in the jig plate must be finished to the appropriate press fit tolerance before installation. Once pressed in, the bushing is not intended for removal or reuse. Ensure the jig plate and all associated workholding are secured before pressing to avoid misalignment.
