Boneham PT2412GT Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM PT2412GT is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in jig and fixture applications. Built to Industry Code P standards, this bushing features an inside diameter of 0.228 inches with a tight tolerance of +0.0001 to +0.0004 inches, a body outside diameter of 3/8 inches, and an overall length of 3/4 inches. Manufactured from steel and hardened to 60 to 65 HRC, it delivers the wear resistance needed for repetitive drilling operations. It is installed via press fit into a prepared drill jig plate and requires no additional locking hardware.

This bushing is suited for use in drill jigs, fixture plates, and tooling setups found in machine shops, fabrication facilities, and production environments. The headless design allows it to sit flush with the jig plate surface, making it appropriate for applications where clearance above the work surface is limited. Machinists, tool and die makers, and fixture builders install this type of bushing during jig construction or as a replacement in existing fixtures experiencing bore wear.

Key Features

• Press fit installation method for secure, permanent seating in jig plates
• Inside diameter of 0.228 inches with tolerance of +0.0001 to +0.0004 inches for precise drill guidance
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Headless design seats flush with jig plate surface
• Meets ANSI standards for drill bushing dimensions and tolerances
• Non-renewable fixed bushing for permanent jig setups

Compatibility

Designed as a standard ANSI-compliant press fit headless drill bushing for use in drill jigs and tooling fixtures requiring a 3/8-inch outside diameter bore and 0.228-inch inside diameter guidance.

Installation Notes

Press fit bushings are typically installed using an arbor press or hydraulic press to avoid damage to the bushing bore or jig plate. Ensure the receiving bore in the jig plate is machined to the correct interference fit tolerance before pressing the bushing into place. Do not drive bushings with a hammer directly on the bore end. Work should be performed by a qualified machinist or toolmaker familiar with jig and fixture assembly practices.
