Boneham P136CW Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P136CW is a headless press fit drill bushing designed to guide drill bits and other cutting tools with precision in jig and fixture applications. Built to ANSI standards, this P-type bushing features a 0.096 inch inside diameter, a 13/64 inch body outside diameter, and a 3/8 inch overall length. Constructed from steel and hardened to 60 to 65 HRC, it provides the wear resistance required for repetitive drilling operations. The inside diameter is held to a tolerance of +0.0001 to +0.0004 inches, ensuring consistent hole location accuracy across production runs.

This bushing is suited for use in tooling plates, drill jigs, and fixture assemblies in machine shops, fabrication environments, and precision manufacturing settings. The headless configuration allows it to sit flush within the jig plate, making it appropriate for applications where a projecting head would interfere with workpiece clearance or tool travel. Machinists and toolmakers press this bushing directly into a prepared hole in the jig plate without the need for a separate liner bushing, as it is a non-renewable style.

Key Features

• Press fit installation into jig plate — no liner bushing required
• Hardened to 60 to 65 HRC for long service life in repetitive drilling applications
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Headless design sits flush with jig plate surface for unobstructed workpiece access
• Manufactured to ANSI standards for dimensional consistency
• Non-renewable, fixed installation style

Compatibility

Designed as an ANSI P-type headless press fit drill bushing for use in standard drill jig plates and fixture tooling where a 13/64 inch OD press fit bore has been prepared.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press or similar pressing equipment to seat the bushing flush into the jig plate bore. The receiving hole in the jig plate must be prepared to the correct press fit tolerance to achieve proper retention. Do not hammer the bushing in directly without a driver or press plate, as this can damage the bore or the bushing. Once pressed in, the bushing is considered permanent and is not intended for removal or replacement.
