Boneham P136CD Press Fit Headless Drill Bushing

Product Description

The BONEHAM P136CD is a headless press fit drill bushing designed to guide cutting tools with precision during drilling operations. It features a 0.076 inch inside diameter, a 13/64 inch body outside diameter, and a 3/8 inch overall length. Machined from steel and hardened to 60 to 65 HRC, this bushing resists wear under repeated drill cycles. The inside diameter tolerance is held to +0.0001 to +0.0004 inches, keeping hole location consistent across production runs. It installs without fasteners, seating directly into a prepared jig plate hole under press force. Licensed machinists, toolmakers, and fixture builders use this bushing in drill jigs and tooling fixtures where repeatable hole placement is required.

This bushing suits precision drilling applications in metalworking environments, including production machining, tool and die work, and custom fixture fabrication. The headless profile keeps the bushing flush with the jig plate surface, which is useful when clearance above the plate is limited or when a smooth top surface is required. It conforms to ANSI standards for drill bushing geometry, making it a direct fit in jig plates dimensioned to the P industry code specification.

Key Features

• Hardened steel construction at 60 to 65 HRC for extended wear life in high-cycle drilling
• Inside diameter tolerance of +0.0001 to +0.0004 inches for consistent tool guidance
• Headless design seats flush with jig plate surface for low-profile installations
• Press fit installation method requires no additional hardware or fasteners
• Meets ANSI standards for P-series drill bushing geometry
• Non-renewable fixed bushing for permanent or long-run jig applications

Compatibility

Designed as an OEM-style replacement or new-installation press fit headless drill bushing for jig plates and tooling fixtures dimensioned to accept a P industry code bushing with a 13/64 inch body outside diameter.

Installation Notes

Press fit drill bushings are installed by toolmakers or machinists using an arbor press or hydraulic press. The receiving bore in the jig plate must be machined to the correct tolerance to achieve proper interference fit. Verify bore size and surface finish before pressing the bushing in place, as the hardened steel body is not designed to be removed once seated. Follow applicable shop safety procedures and use appropriate pressing fixtures to keep the bushing square during installation.
