Boneham CB00001268 Press Fit Headless Drill Bushing

Product Description

The BONEHAM CB00001268 is a press fit headless drill bushing used to guide drill bits and cutting tools with precision in jig and fixture applications. Assigned industry code P, this bushing features an inside diameter of 0.152 inches with a tolerance of +0.0001 to +0.0004 inches, a body outside diameter of 5/16 inches, and an overall length of 1 inch. Manufactured from steel, it provides the wear resistance and dimensional stability required for repetitive production drilling. Machinists and toolmakers rely on this style of bushing to maintain hole location accuracy across high-volume runs without the need for renewable liner bushings.

This headless press fit bushing is suited for direct installation into drill jigs, fixtures, and tooling plates where a flush or below-surface profile is required. The headless design allows the bushing to sit fully within the parent material, making it appropriate for applications where a flanged bushing would interfere with workpiece clearance or clamping. It is a non-renewable design, meaning it is pressed permanently into the jig body and is not intended for field replacement during production cycles.

Key Features

• Press fit installation for permanent, stable seating in jig plates and fixture bodies
• Inside diameter of 0.152 inches with a close tolerance of +0.0001 to +0.0004 inches for accurate drill guidance
• Headless design provides a flush profile with no flange interference
• Steel construction delivers wear resistance for repetitive drilling operations
• Industry code P designation for standard identification and cross-reference
• Non-renewable, single-piece construction for permanent jig applications

Compatibility

Designed as an OEM-style replacement or original-installation press fit headless drill bushing for use in steel and cast-iron drill jigs and fixtures requiring a 5/16-inch bore and 0.152-inch drill guide diameter.

Installation Notes

Installation of press fit drill bushings is typically performed by a machinist or toolmaker using an arbor press or hydraulic press to drive the bushing squarely into the prepared hole. The receiving bore in the jig plate must be machined to the appropriate interference fit tolerance before pressing. Do not hammer the bushing in directly without a driver to avoid distorting the bore or the bushing body. Once pressed in, this bushing is not designed for removal or reuse.
