Boneham AM00000495 Drill Bushing Pm 22.5 Inch Id

Product Description

The BONEHAM AM00000495 is a press fit headless drill bushing with a PM industry code, designed to guide drill bits with precision in jig and fixture applications. Manufactured from steel, this bushing features an inside diameter of 22.5 inches, a body outside diameter of 35.00 millimeters, and an overall bushing length of 36.00 millimeters. It is installed using a press fit method, seating firmly into a drill jig plate without requiring a retaining screw or flange. Machinists, tool-and-die professionals, and precision fabrication shops rely on this style of bushing to maintain accurate hole location and extend the service life of drill jigs.

This bushing is suited for use in production drilling, reaming, and boring operations where a permanent, flush-mount guide is required. The headless design keeps the bushing face level with the jig plate surface, making it appropriate for applications where chip clearance or close-tolerance workpiece clamping is a priority. It is not a renewable bushing, meaning it is intended for fixed installations where bushing replacement is not a routine maintenance requirement. Typical environments include machine shops, tool rooms, and manufacturing fixtures operating under standard production conditions.

Key Features

• Press fit installation method for a secure, permanent seat in the jig plate
• PM bushing industry code designation for standardized application matching
• Steel construction for durability and wear resistance in drilling operations
• Headless profile sits flush with the jig plate surface for close-clearance workholding
• Non-renewable design intended for fixed, long-service-life installations
• Inside diameter of 22.5 inches to accommodate the corresponding drill or tool shank

Compatibility

Designed as a standard PM-code press fit headless drill bushing for use in drill jigs and fixtures requiring a permanently installed steel guide bushing.

Installation Notes

Press fit bushings are typically installed by a machinist or toolmaker using an arbor press or hydraulic press to drive the bushing squarely into a properly sized jig plate bore. The receiving hole in the jig plate must be machined to the correct interference fit tolerance before installation. Attempting to hammer the bushing in without a press can damage the bushing or distort the plate. Once pressed in, the bushing is not intended to be removed and reused.
