Boneham H2612HD Press Fit Headless Drill Bushing

Product Description

The BONEHAM H2612HD is a press fit headless drill bushing designed to guide drill bits and other cutting tools with precision in jig and fixture applications. Built to Industry Code H, this bushing features a 0.246 inch inside diameter with a tight tolerance of +0.0001 to +0.0004 inches, ensuring accurate hole placement and consistent results across repeated operations. The body measures 13/32 inches in outside diameter and 3/4 inches in overall length. Manufactured from steel hardened to 60 to 65 HRC, it delivers the wear resistance required for production drilling environments. This part is installed by machinists, toolmakers, and fixture builders working to ANSI standards.

The H2612HD is suited for use in drill jigs where a permanent, non-renewable bushing is required. Its headless design allows flush mounting in jig plates, making it appropriate for applications where the bushing face must sit below or level with the jig surface. The press fit installation method provides a secure, non-rotating fit without the need for locking hardware. This bushing is a single-piece, non-renewable component intended for fixed installations in both prototype and production tooling setups.

Key Features

• Industry Code H headless design allows flush or sub-flush installation in jig plates
• Press fit retention eliminates the need for locking screws or retaining rings
• Steel construction hardened to 60 to 65 HRC for high wear resistance
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise drill guidance
• Meets ANSI standards for drill bushing dimensions and performance
• Non-renewable fixed installation — no disassembly required after press fit

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and fixtures requiring a press fit headless bushing conforming to ANSI Industry Code H specifications with a 0.246 inch inside diameter.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press or hydraulic press to seat the bushing into a precision-bored jig plate hole. The receiving bore must be machined to the correct press fit tolerance to ensure proper retention and concentricity. Once pressed in, this bushing is not designed for removal or replacement — verify placement before seating. Follow applicable ANSI tooling standards for jig plate preparation and bushing installation procedures.
