Boneham PT4010JE Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT4010JE is a press fit headless drill bushing designed to guide cutting tools accurately during drilling, reaming, and boring operations. With an inside diameter of 0.348 inches (Letter size S) and a body outside diameter of 5/8 inch, this bushing installs flush into a jig plate without a protruding head, making it suitable for applications where a low-profile surface is required. Hardness is rated at 60 to 65 HRC for wear resistance during repetitive tooling operations. The inside diameter tolerance is held to +0.0001 to +0.0005 inches, ensuring consistent tool guidance. Machinists and tooling professionals install this component in production jigs and fixtures.

This bushing is used in machining and fabrication environments where precise, repeatable hole location is critical. The headless press fit design is common in fixed jig applications where the bushing is permanently installed into the jig body. It is appropriate for use in production drilling setups across general metalworking, manufacturing, and machining shops. The overall bushing length of 5/8 inch suits standard jig plate thicknesses in light to medium production tooling.

Compatibility

Designed as an OEM-style replacement or new-installation press fit headless drill bushing conforming to ANSI standards, suitable for use in standard drill jig fixtures accepting a 5/8 inch outside diameter bushing with a 0.348 inch bore.

Installation Notes

Installation is performed by machinists or tooling engineers using an arbor press or bushing press tool to seat the bushing flush into the jig plate bore. The jig plate bore must be machined to the correct tolerance fit before pressing the bushing in place — do not force a bushing into an undersized or improperly finished bore. Once pressed in, this bushing is not renewable and is intended for permanent installation. Follow applicable shop safety procedures and power down all equipment before inspecting or servicing jig components.
