Boneham P6412LZ Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P6412LZ is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Manufactured from steel and hardened to 60 to 65 HRC, this bushing resists wear under continuous drilling operations. The 37/64 inch inside diameter accepts standard drill sizes within the P bushing industry code classification, while the 1 inch outside diameter and 3/4 inch overall length suit common jig plate thicknesses. Machinists, toolmakers, and fixture builders install this bushing to maintain accurate hole location across repeated drilling cycles.

This bushing is intended for use in drill jigs, production fixtures, and tooling plates where a permanent, non-renewable installation is required. The headless profile sits flush with the jig plate surface, making it well suited for applications where a protruding head would interfere with workpiece seating or clamping. It is a standard P-series bushing per ANSI specifications, fitting production environments that demand consistent hole-to-hole repeatability on steel, aluminum, and similar workpiece materials.

Key Features

• Press fit installation for a permanent, fixed mount in the jig plate bore
• Headless design sits flush with the plate surface to avoid workpiece interference
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Inside diameter tolerance of +0.0001 to +0.0005 inches for precise drill guidance
• ANSI-standard P bushing industry code for broad tooling compatibility
• Compact 3/4 inch overall length suits standard jig plate thicknesses

Compatibility

Designed as a permanent press fit replacement or new-installation bushing for drill jigs and fixtures requiring a P-series headless bushing with a 37/64 inch inside diameter and 1 inch outside diameter per ANSI standards.

Installation Notes

Installation is performed by toolmakers or machinist tradespeople using an arbor press or hydraulic press to seat the bushing flush and square in a prepared jig plate bore. Verify the receiving bore diameter and finish before pressing to avoid bushing distortion or bore damage. Because this is a non-renewable bushing, removal typically requires the bore to be re-machined; plan installation location carefully. Always power down and de-energize any automated machinery before servicing or replacing tooling fixtures.
