Boneham P5622MK Press Fit Headless Drill Bushing

Product Description

The BONEHAM P5622MK is a press fit headless drill bushing designed to guide drill bits with precision in jig and fixture applications. This Type P bushing measures 41/64 inches inside diameter and 7/8 inches outside diameter, with an overall length of 1-3/8 inches. Manufactured from steel, it delivers the durability required for repetitive drilling operations in production and maintenance environments. The headless design allows the bushing to sit flush within the drill jig plate, making it well suited for applications where a low-profile installation is required. Licensed machinists and tooling technicians are the primary installers of this component.

This bushing is used in drill jig assemblies across light manufacturing, metalworking shops, and maintenance repair operations. It is a fixed, non-renewable bushing, meaning it is pressed permanently into the jig plate and is not intended for routine field replacement. Typical applications include guiding twist drills, reamers, and similar cutting tools to a precise location on a workpiece. It is appropriate for both production-run fixtures and one-off tooling setups where consistent hole placement is critical.

Key Features

• Press fit installation method for permanent, rigid seating in drill jig plates
• Headless design provides a flush, low-profile fit within the jig body
• Inside diameter tolerance of +0.0001 to +0.0005 inches ensures close guidance of cutting tools
• 41/64 inch ID accommodates standard drill and reamer sizes in that range
• Steel construction for wear resistance in repetitive drilling cycles
• Non-renewable fixed bushing — suited for permanent jig installations

Compatibility

Designed as an OEM-style fixed drill bushing for use in drill jig plates requiring a Type P press fit headless bushing with a 41/64 inch inside diameter and 7/8 inch outside diameter.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush into a pre-bored jig plate hole. Ensure the receiving bore is machined to the correct interference fit tolerance before pressing to avoid damage to the bushing or plate. Once pressed in, this bushing is not designed for removal and reuse. Follow standard shop safety practices and power down any associated machinery before working on jig assemblies.
