Boneham PT248GO Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT248GO is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in jig and fixture applications. Manufactured from steel, this bushing features a 7/32 inch inside diameter and a 3/8 inch body outside diameter, with an overall length of 1/2 inch. The headless design allows it to sit flush within the jig plate, making it well suited for close-clearance layouts where a headed bushing would interfere. It is installed by press fitting directly into a hardened or soft jig plate bore. Machinists, tool and die makers, and production fixture builders are the primary users of this component.

This drill bushing is used in drilling jigs and production fixtures across metalworking, manufacturing, and machining environments. The industry code P designation identifies it within the standard bushing series used in tooling design. It is appropriate for both prototype and high-volume production setups where repeatable hole location accuracy is required. The bushing is non-renewable, meaning it is pressed in permanently rather than used with a liner bushing system.

Key Features

• Press fit installation method for permanent, secure seating in jig plates
• Headless design allows flush mounting in tight or closely spaced layouts
• 7/32 inch inside diameter with a tolerance of plus 0.0001 to plus 0.0004 inches for close drill guidance
• 3/8 inch body outside diameter and 1/2 inch overall length
• Steel construction provides hardness and wear resistance for repeated drill passes
• Industry code P designation for standardized tooling compatibility

Compatibility

Designed as a standard P-series press fit headless drill bushing for use in machining jigs and fixtures requiring a 3/8 inch bore and 7/32 inch drill guidance.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press to drive the bushing into a correctly sized and toleranced bore in the jig plate. The receiving bore should be machined to the appropriate press fit tolerance before installation to avoid bushing distortion. Once pressed in, this bushing is not intended for removal or reuse. Verify bore alignment and cleanliness before pressing to ensure proper seating and drill guidance accuracy.
