Boneham CB00001115 Press Fit Headless Drill Bushing

Product Description

The BONEHAM CB00001115 is a press fit headless drill bushing used to guide cutting tools with precision during drilling, reaming, and boring operations. Assigned industry code P, this bushing features a 0.257 inch inside diameter (Letter F, Decimal 0.2570 inches) and a 13/32 inch body outside diameter, with a 1 inch overall length. Manufactured from steel and hardened to 60 to 65 HRC, it delivers the wear resistance and dimensional stability required in production jig and fixture applications. The tight inside diameter tolerance of +0.0001 to +0.0005 inches ensures repeatable tool guidance across high-cycle use.

This bushing is suited for use in drill jigs, fixture plates, and tooling setups found in machine shops, manufacturing facilities, and precision fabrication environments. The headless, non-renewable design means it is pressed directly into the jig plate and intended as a permanent installation. Machinists, toolmakers, and jig builders select this style when a low-profile flush installation is required and the bushing does not need to be routinely changed between operations.

Key Features

• Industry code P designation for standardized jig bushing identification
• 0.257 inch inside diameter with a tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Headless, press fit design for permanent flush installation in jig plates
• 1 inch overall length provides adequate tool guidance depth for typical drilling operations
• Conforms to ANSI standards for interchangeability in standard tooling setups

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and fixture plates requiring a press fit headless bushing with a 0.257 inch bore and 13/32 inch outside diameter per ANSI standards.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush into the jig plate bore. The receiving hole in the jig plate must be machined to the appropriate interference fit tolerance before pressing to avoid bushing distortion or bore damage. Because this is a non-renewable bushing, removal typically requires the bushing to be driven or pressed out and replaced. Verify hole depth and plate thickness against the 1 inch overall bushing length before installation.
