Boneham P4016JB Headless Drill Bushing 11/32 Id 5/8 Od

Product Description

The BONEHAM P4016JB is a headless press fit drill bushing designed to guide drill bits and reamers with precision in jig and fixture applications. Manufactured from steel with a hardness of 60 to 65 HRC, this bushing delivers consistent bore accuracy and resists wear under repeated use. The inside diameter is 11/32 inches with a tight tolerance of plus 0.0001 to plus 0.0005 inches, ensuring reliable tool guidance. The body outside diameter measures 5/8 inches and the overall length is 1 inch. It meets ANSI standards and is installed by press fit without a head flange, making it suitable where flush or sub-flush mounting is required.

This bushing is used in drill jigs, fixture plates, and tooling setups across machine shops, manufacturing facilities, and production environments. The headless design allows it to sit flush with or below the jig surface, which is common in applications where clearance is limited or where multiple operations share a single jig plate. Machinists and tooling technicians specify this style when the bushing must be permanently installed rather than quickly changed between operations.

Key Features

• Press fit installation method for permanent, secure seating in jig plates
• Headless design for flush or sub-flush mounting where flange clearance is not available
• 11/32 inches inside diameter with a tolerance of plus 0.0001 to plus 0.0005 inches for precise tool guidance
• 60 to 65 HRC hardness for long service life in high-cycle drilling applications
• Steel construction providing strength and wear resistance
• Meets ANSI standards for drill bushing dimensional requirements

Compatibility

Designed as a permanent press fit headless drill bushing conforming to ANSI P-series dimensional standards, compatible with drill jig plates and tooling fixtures bored to accept a 5/8 inches outside diameter press fit bushing.

Installation Notes

Press fit bushings are installed by toolmakers or machinists using an arbor press or hydraulic press to drive the bushing into a precisely bored hole in the jig plate. The bore in the receiving plate must be machined to the correct interference fit tolerance before installation. Once pressed in, this bushing is not designed for removal or replacement. Ensure the jig plate is properly fixtured and supported to prevent distortion during pressing.
