Boneham PT366IF Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM PT366IF is a headless drill bushing designed for press fit installation in jig plates and tooling fixtures. It guides drill bits and other cutting tools with precision, maintaining consistent hole location across repeated operations. The bushing carries a 19/64-inch inside diameter, a 9/16-inch body outside diameter, and an overall length of 3/8 inch. Constructed from steel, it provides the wear resistance required for production drilling applications. Because it is headless, it sits flush with the jig plate surface, making it well suited for close-tolerance work where a flanged head would interfere with the workpiece or fixture setup.

This bushing is used in drill jigs, fixture plates, and tooling setups across metalworking, machining, and manufacturing environments. It is installed once and left in place, as it is a non-renewable type. The press fit design locks the bushing securely into the jig plate bore without fasteners or locking collars. Machinists, tool and die makers, and fixture builders are the primary installers. The bushing code P designates its industry-standard size classification, which simplifies cross-referencing with jig and fixture design standards.

Key Features

• Headless design sits flush with the jig plate surface for close-clearance applications
• Press fit installation method eliminates the need for additional locking hardware
• 19/64-inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches for accurate tool guidance
• Steel construction provides durability and wear resistance in production environments
• Non-renewable fixed bushing for permanent single-station installation
• Industry bushing code P for straightforward specification and replacement reference

Compatibility

Designed as a standard press fit headless drill bushing conforming to industry code P, suitable for use in jig plates and tooling fixtures bored to accept a 9/16-inch outside diameter press fit bushing.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press or similar controlled pressing equipment. The receiving bore in the jig plate must be finish-reamed to the appropriate press fit tolerance before installation. Once pressed in, the bushing is not intended for removal or reuse. Confirm the jig plate material and bore tolerance meet the requirements for a permanent press fit before installation.
