Boneham AM00000747 Press Fit Headless Drill Bushing Pm

Product Description

The BONEHAM AM00000747 is a press fit headless drill bushing with industry code PM, designed to guide drill bits and boring tools with precision during machining operations. Manufactured from steel, this bushing features a 9.6-inch inside diameter and a body outside diameter of 15.00 millimeters, with an overall length of 20.00 millimeters. The headless, press fit design allows the bushing to seat flush and securely into a jig plate without the use of a locking collar or head flange. It is installed by machinists and tooling technicians working in production drilling and jig-boring applications where repeatable hole location is critical.

This bushing is suited for use in drill jigs and fixture plates in both production shop and maintenance machining environments. The PM industry code designation identifies it as a standard headless press fit type following established tooling conventions. It is a non-renewable bushing, meaning it is pressed permanently into the jig plate and is not intended for routine replacement without re-machining the liner hole. Applications include precision drilling, reaming, and light boring where positional accuracy must be maintained across repeated operations.

Key Features

• Press fit installation method seats the bushing securely without additional fasteners or collars
• Headless design provides a flush, low-profile fit within the jig plate surface
• Steel construction for durability under repeated drill cycle contact
• PM industry code designation meets standard tooling classification for headless press fit bushings
• Non-renewable configuration - permanently installed for stable, long-term fixture use
• Compact 20.00 millimeter overall length suits thin and medium-thickness jig plates

Compatibility

Designed as an OEM-style replacement or new-installation component for standard drill jig fixtures requiring a PM-type headless press fit bushing with a 9.6-inch inside diameter.

Installation Notes

Installation is performed by a machinist or tooling technician using an arbor press or hydraulic press to seat the bushing into a pre-machined liner hole in the jig plate. The receiving hole must be machined to the correct tolerance for an interference fit before pressing. Do not hammer the bushing directly without a suitable press arbor, as this may damage the bushing bore or distort the outer diameter. Once pressed in, this bushing is not designed for removal and reinstallation.
