Boneham AM00000719 Drill Bushing Pm 8.7 Inch Id

Product Description

The BONEHAM AM00000719 is a press fit headless drill bushing manufactured from steel and designated under industry code PM. It is designed to guide drill bits with precision during machining operations, maintaining accurate hole location and reducing bit deflection. With an inside diameter of 8.7 inches, this bushing presses directly into a jig plate without requiring a liner bushing or locking mechanism. It is installed by machinists and tool and die professionals working in production drilling, jig boring, and fixture fabrication environments.

This bushing is suited for use in drill jigs and fixture plates where a permanent, non-renewable guide bushing is required. The headless press fit design provides a flush or sub-flush installation profile, making it appropriate for applications where clearance above the jig surface is limited. It is a standard catalog component used across general metalworking, automotive tooling, and precision manufacturing shops.

Key Features

• Press fit installation - no liner bushing or retaining ring required
• Headless design allows flush installation with jig plate surface
• PM industry code designation for standardized interchangeability
• Steel construction for durability in repetitive drilling applications
• Non-renewable bushing intended for permanent fixture installations

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and fixture plates requiring a PM-coded press fit headless drill bushing with an 8.7-inch inside diameter.

Installation Notes

Press fit bushings are installed by machinists using an arbor press or hydraulic press to seat the bushing flush with the jig plate. Power down all associated drilling equipment before installation or removal. Ensure the receiving bore is machined to the appropriate tolerance for a press fit before installing to avoid damage to the bushing or the fixture plate. Removal of a press fit bushing typically requires a bushing driver or punch and should be performed carefully to avoid distorting the bore.
