Boneham AM00000561 Press Fit Headless Drill Bushing Pm

Product Description

The BONEHAM AM00000561 is a press fit headless drill bushing in the PM industry code series, designed to guide drill bits with precision in production and tooling applications. Made from steel, this bushing installs without a head flange, seating flush within the jig plate for a clean, low-profile fit. The inside diameter measures 4.4 inches, providing the clearance needed for large-diameter drill guidance. With an outside body diameter of 8.00 mm and an overall length of 12.00 mm, it is a compact component suited for tight fixture layouts. Machinists and toolroom technicians working with drill jigs specify this type of bushing where headless geometry is required.

This bushing is used in metalworking drill jigs and fixture plates that call for a press fit, non-renewable liner. It is appropriate for production environments where the bushing is installed once and replaced with the entire jig plate at end of service life. Typical applications include repetitive drilling operations in manufacturing and fabrication shops where hole location accuracy is critical across high part volumes.

Key Features

• Press fit installation method - no secondary hardware or fasteners required
• Headless PM series design seats flush with jig plate surface
• Steel construction for durability in production drilling environments
• 4.4-inch inside diameter for large-bore drill guidance
• Non-renewable design suited for permanent fixture installations

Compatibility

Designed as an OEM-style replacement or new-build component for drill jig fixtures requiring a PM-series press fit headless drill bushing with a 4.4-inch inside diameter.

Installation Notes

Press fit bushings are typically installed by toolroom machinists or fixture builders using an arbor press or hydraulic press to achieve the required interference fit. Always verify bore tolerance in the jig plate before pressing to avoid cracking or distortion. Do not drive the bushing with impact tools, as this can damage the bushing seat or alter the bore geometry.
