Boneham P8812NM Press Fit Headless Drill Bushing

Product Description

The BONEHAM P8812NM is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in metalworking and machining applications. Built to Bushing Industry Code P, this bushing features a 0.8125 inch (13/16 inch) inside diameter, a 1-3/8 inch outside diameter, and a 3/4 inch overall length. Constructed from hardened steel at 60 to 65 HRC, it delivers the wear resistance required for repetitive drilling operations in production jig and fixture setups. The headless design allows flush installation in tight clearance environments where a flanged head is not practical.

This bushing is suited for use in drill jigs, fixtures, and tooling plates across manufacturing, fabrication, and machine shop environments. The press fit installation method means the bushing is driven permanently into a prepared hole in the jig plate — no liner bushing is required. It is a fixed, non-renewable style appropriate for high-volume production runs where the bushing remains in place for the life of the fixture. Machinists, tool and die makers, and fixture builders are the typical installers.

Key Features

• Bushing Industry Code P — standardized sizing for direct interchangeability in ANSI-compliant tooling
• 0.8125 inch inside diameter with a tight tolerance of +0.0002 to +0.0006 inches for consistent drill guidance
• 1-3/8 inch body outside diameter for secure press fit retention in the jig plate
• Hardened steel construction at 60 to 65 HRC for extended tool life under repeated drilling cycles
• Headless profile allows flush or sub-flush installation in space-constrained fixtures
• Non-renewable, permanent installation style — ideal for dedicated high-volume drilling operations

Compatibility

Designed as an ANSI-standard press fit headless drill bushing for use in drill jigs and machining fixtures requiring a Bushing Industry Code P bushing with a 13/16 inch inside diameter and 1-3/8 inch outside diameter.

Installation Notes

Press fit bushings are installed by a machinist or tool and die maker using an arbor press or hydraulic press into a precisely reamed hole in the jig plate. The receiving hole must be machined to the correct interference fit tolerance per ANSI standards before installation. Once pressed in, this bushing is not intended for removal or replacement. Always ensure the fixture is secured and de-energized from any automated equipment before pressing the bushing into position.
