Boneham P405JB Headless Drill Bushing 11/32 in Id Steel

Product Description

The BONEHAM P405JB is a press fit headless drill bushing designed to guide cutting tools accurately during drilling, reaming, and similar machining operations. Manufactured from steel, this bushing carries industry code P and features an inside diameter of 11/32 inches with a tight tolerance of +0.0001 to +0.0005 inches, ensuring precise tool guidance and repeatable hole location. The outside diameter measures 5/8 inches and the overall length is 5/16 inches. Its headless design allows flush installation in jig plates where a protruding flange would interfere with workpiece clearance. Machinists, toolmakers, and jig-and-fixture builders install this type of component in drill jigs and production fixtures.

This bushing is suited for use in drill jigs, fixture plates, and tooling setups across metalworking, fabrication, and production machining environments. The press fit installation method means the bushing is driven directly into a prepared hole in the jig plate and held in place by interference fit without fasteners or locking mechanisms. It is appropriate for fixed, non-renewable tooling applications where the bushing does not need to be replaced during the production run. The P industry code designates a standard headless press fit bushing per common tooling standards, making it straightforward to cross-reference within existing fixture designs.

Key Features

• Inside diameter of 11/32 inches with tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• Outside diameter of 5/8 inches and overall length of 5/16 inches for compact installation
• Headless design allows flush seating in jig plates without flange interference
• Press fit installation - no locking collar or fasteners required
• Steel construction provides durability under repeated tool contact
• Non-renewable, fixed-position bushing suitable for high-volume production fixtures

Compatibility

Designed as an OEM-style replacement or new-installation press fit headless drill bushing conforming to industry code P, suitable for standard drill jig plates and fixture assemblies requiring an 11/32-inch bore guide.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or similar pressing equipment to drive the bushing into a properly sized and finished hole in the jig plate. The mating hole in the jig plate must be machined to the appropriate interference fit tolerance to retain the bushing securely without distorting the bore. Do not hammer the bushing in without a driver or press block, as this can damage the bore or cause misalignment. Once pressed in, the bushing is not intended to be removed and reused.
