Boneham AM00000648 Press Fit Headless Drill Bushing Pm

Product Description

The BONEHAM AM00000648 is a press fit headless drill bushing conforming to the PM industry code, designed for use in drill jigs and fixture tooling applications. Manufactured from steel, this bushing is installed by pressing directly into a jig plate without the use of a retaining flange or locking mechanism. It features a 6.8-inch inside diameter and a body outside diameter of 12.00 millimeters, with an overall bushing length of 16.00 millimeters. This style of headless bushing is a non-renewable type, meaning it is pressed permanently into the jig body and is not intended for routine field replacement.

Press fit headless drill bushings of the PM type are used in production and toolroom environments where a flush, low-profile bushing installation is required. They guide drill bits, reamers, and other cutting tools to precise locations during machining operations. This bushing is appropriate for use in steel or hardened jig plates in light to medium-duty drilling applications. Machinists, toolmakers, and fixture builders are the primary installers.

Key Features

• PM industry code headless design for flush, flangeless press fit installation
• 6.8-inch inside diameter for precise tool guidance
• Steel construction for durability in production machining environments
• Non-renewable fixed installation — pressed permanently into jig plate
• Body outside diameter of 12.00 millimeters and overall length of 16.00 millimeters

Compatibility

Designed as an OEM-style replacement or new-installation bushing for drill jigs and fixture tooling requiring PM-code press fit headless bushings with a 6.8-inch inside diameter.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush into the jig plate bore. The mating bore in the jig plate must be machined to the correct interference fit tolerance for a PM-style bushing before pressing. Once installed, this non-renewable bushing is not designed for removal and reinstallation. Consult applicable tooling standards for proper press fit tolerances before machining the receiving hole.
