Boneham CB00001066 Headless Drill Bushing 1/8 in Id Steel

Product Description

The BONEHAM CB00001066 is a headless, press fit drill bushing designed to guide cutting tools with precision in jig and fixture applications. Manufactured from steel with a hardness rating of 60 to 65 HRC, this Type P bushing delivers the wear resistance required for repetitive drilling operations. The inside diameter measures 0.125 inches with a tolerance of +0.0001 to +0.0004 inches, ensuring accurate tool guidance. The body outside diameter is 0.25 inches and the overall length is 0.75 inches. It meets ANSI standards and is installed permanently without the ability to be renewed or replaced in service.

This bushing is suited for use in drill jigs and production fixtures where a permanent, flush-mount guide is required. The headless profile sits flush with or below the jig plate surface, making it appropriate for applications where a protruding head would interfere with workpiece contact or clamping. Machinists, tool and die makers, and precision fabrication shops use this type of bushing when drilling operations must be repeated with consistent positional accuracy across multiple workpieces.

Key Features

• Press fit installation method for permanent, non-renewable seating in the jig plate
• Headless design provides a flush or sub-flush profile for unobstructed workpiece contact
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Meets ANSI standards for drill bushing dimensions and performance
• Compact size — 0.125 inches ID, 0.25 inches OD, 0.75 inches overall length

Compatibility

Designed as an OEM-style Type P press fit headless drill bushing for use in standard ANSI-compliant jig plates and fixture assemblies requiring a 0.25-inch body outside diameter bore.

Installation Notes

Press fit bushings are installed by a toolmaker or machinist using an arbor press or hydraulic press into a precisely reamed hole in the jig plate. The receiving bore in the jig plate must be machined to the correct interference fit tolerance to retain the bushing securely without distorting the inside diameter. Once pressed in, this bushing is not designed to be removed or renewed. Always verify bore alignment and cleanliness before pressing to avoid galling or misalignment.
