Boneham PT126BJ Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT126BJ is a press fit headless drill bushing designed to guide cutting tools with precision in production drilling and machining operations. Manufactured from steel with a hardness rating of 60 to 65 HRC, this bushing resists wear and maintains dimensional accuracy over repeated use. The PT126BJ carries an inside diameter of 0.052 inches (Wire Gauge #55) with a tolerance of +0.0001 to +0.0004 inches, an outside diameter of 3/16 inches, and an overall length of 3/8 inches. It installs without fasteners, pressed directly into a drill jig plate for a secure, flush fit. Machinists and tool-and-die professionals rely on this type of bushing for consistent hole location in jig and fixture work.

This bushing is suited for use in drill jig fixtures across light manufacturing, tool rooms, and precision machining environments. The headless, press fit design keeps the bushing flush with the jig plate surface, making it appropriate for close-tolerance applications where a flanged head would interfere with workpiece clearance or tool travel. It conforms to ANSI standards, making it compatible with standard jig plate layouts requiring a P-series industry code bushing.

Key Features

• Press fit installation — no fasteners required, seats flush in jig plate bore
• Headless design eliminates flange interference in tight clearance setups
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• ANSI-compliant P-series bushing industry code for standardized fitment
• Non-renewable design intended for permanent press fit installations

Compatibility

Designed as an ANSI-standard P-series press fit headless drill bushing for use in drill jig plates and fixtures requiring a 3/16 inch outside diameter, 0.052 inch inside diameter bushing.

Installation Notes

Installation is typically performed by a machinist or tool-and-die technician using an arbor press to seat the bushing flush into a properly reamed jig plate bore. Ensure the receiving bore is reamed to the correct interference fit tolerance before pressing to avoid cracking the jig plate or distorting the bushing. De-energize or lock out any associated machine before performing jig maintenance or bushing replacement. This is a permanent, non-renewable bushing and is not intended for field removal and reinstallation.
