Boneham PT365JB Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT365JB is a headless press fit drill bushing designed to guide cutting tools accurately during drilling, reaming, and boring operations. Conforming to ANSI standards and assigned industry code P, this bushing features an inside diameter of 11/32 inches with a close tolerance of +0.0001 to +0.0005 inches, a body outside diameter of 9/16 inches, and an overall length of 5/16 inches. Manufactured from steel hardened to 60 to 65 HRC, it provides long service life in production jig and fixture applications. Machinists and toolmakers typically install these bushings in drill jigs used in metalworking shops and manufacturing facilities.

The PT365JB suits applications where a flush, headless profile is required and the bushing is intended to remain permanently in place without renewal. It is appropriate for fixed jig plate installations where precision tool guidance is needed and vertical clearance above the jig plate surface must be kept to a minimum. The compact 5/16-inch length makes it suitable for thinner jig plates while still providing adequate tool guidance length for standard drilling operations.

Key Features

• Headless press fit design installs flush with the jig plate surface for minimal clearance applications
• Inside diameter tolerance of +0.0001 to +0.0005 inches ensures precise tool guidance and repeatable hole location
• Steel construction hardened to 60 to 65 HRC for wear resistance in high-cycle drilling operations
• ANSI-compliant P-series industry code for standardized sizing and interchangeability
• Non-renewable fixed installation suited for permanent jig setups

Compatibility

Designed as an ANSI P-series OEM-style press fit headless drill bushing for use in standard drill jig plates requiring an 11/32-inch inside diameter tool guide.

Installation Notes

Press fit bushings are installed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush into the jig plate bore. The receiving bore in the jig plate must be machined to the correct press fit tolerance to ensure proper retention. Because this is a permanent non-renewable bushing, confirm placement before pressing fully into position. Always follow applicable shop safety procedures and de-energize any associated machinery before working in the fixture area.
