Boneham CB00001274 Press Fit Headless Drill Bushing

Product Description

The BONEHAM CB00001274 is a press fit headless drill bushing designed to guide drill bits and other cutting tools with precision in jig and fixture applications. Carrying industry code P, this bushing features a 0.147 inch inside diameter with a tolerance of +0.0001 to +0.0004 inches, a 5/16 inch body outside diameter, and a 1 inch overall length. Constructed from steel, it is pressed directly into a drill jig plate without a head or collar. Machinists, toolmakers, and fixture builders install these bushings to maintain accurate hole location across repeated drilling operations.

This bushing is suited for production drilling applications in metalworking shops, tool rooms, and manufacturing environments. It fits into jig plates wherever a flush, headless installation is required and the bushing is not intended to be replaced during the life of the fixture. The non-renewable, press fit design keeps the bushing permanently seated, making it appropriate for high-volume, dedicated tooling setups where repeatability and rigidity are the priority.

Key Features

• Industry code P headless press fit design for permanent, flush installation in drill jigs
• 0.147 inch inside diameter with tight tolerance of +0.0001 to +0.0004 inches for accurate tool guidance
• 5/16 inch body outside diameter for consistent press fit seating
• 1 inch overall length provides stable support along the drill axis
• Steel construction for durability in repetitive drilling operations
• Non-renewable design eliminates head protrusion for clean jig plate surfaces

Compatibility

Designed as an OEM-style replacement or new-build component for standard drill jig fixtures requiring a P-series headless press fit bushing with a 0.147 inch inside diameter and 5/16 inch outside diameter.

Installation Notes

Press fit bushings are typically installed by toolmakers or machinists using an arbor press. The jig plate bore should be finished to the appropriate tolerance before pressing to avoid damaging the bushing or distorting the inside diameter. Once pressed in, this bushing is not designed for removal or replacement. Verify bore alignment and cleanliness before installation to ensure proper seating.
