Boneham PT128CF Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM PT128CF is a Type P press fit headless drill bushing manufactured from steel, used to guide drill bits with precision in jig and fixture applications. With an inside diameter of 5/64 inches and a body outside diameter of 3/16 inches, this bushing provides accurate hole location and repeatable drilling alignment. The overall length is 1/2 inch. The headless design allows flush or sub-flush seating in jig plates where a headed bushing would interfere with the workpiece or tooling path. Licensed machinists, toolmakers, and fixture builders install this type of bushing in production and prototype drilling operations.

The PT128CF is suited for use in drill jigs, fixture plates, and tooling bodies where consistent hole placement is required across repeated operations. The press fit installation method locks the bushing permanently in the jig plate bore, making it appropriate for high-cycle applications where the bushing does not need to be swapped between operations. It is not a renewable bushing. Typical applications include metalworking, fabrication shops, and any production environment requiring tight positional tolerance on drilled holes.

Key Features

• Type P bushing industry code for standardized interchangeability
• Press fit installation for permanent, secure seating in jig plate
• Headless design allows flush mounting without workpiece interference
• Inside diameter tolerance of plus 0.0001 to plus 0.0004 inches for close drill guidance
• Steel construction for durability in production drilling environments
• Non-renewable design suited for fixed, high-cycle drill jig applications

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and fixture plates requiring a Type P press fit headless drill bushing with a 5/64 inch inside diameter and 3/16 inch outside diameter.

Installation Notes

Press fit bushings are typically installed by toolmakers or machinist trades using an arbor press or hydraulic press to seat the bushing flush within a precision-bored jig plate hole. The receiving bore in the jig plate must be machined to the appropriate interference fit tolerance before installation. Once pressed in, the bushing is not intended to be removed or replaced. Always verify bore size and alignment before pressing to avoid damage to the bushing or jig plate.
