Boneham AM00000325 Press Fit Headless Drill Bushing Hm

Product Description

The BONEHAM AM00000325 is a press fit headless drill bushing with an HM industry code, designed to guide drill bits with precision in jig and fixture applications. Made from steel, this bushing is pressed directly into a drill jig plate without a locking collar or head, creating a clean, flush mounting surface. It carries an inside diameter of 9.25 inches, a body outside diameter of 15.00 mm, and an overall length of 25.00 mm. Machinists and toolmakers install this type of bushing during fixture assembly or tooling setup in manufacturing and fabrication environments.

This bushing is suited for production drilling operations where a permanent, renewable-free installation is acceptable. The headless design keeps the top surface of the jig plate unobstructed, which is useful in tight fixture layouts. Typical applications include metalworking jigs in machine shops, production tooling for repetitive hole location, and fixture builds requiring consistent drill guidance across multiple workpieces.

Key Features

• HM industry code classification for standard press fit headless bushing selection
• Steel construction for durability under repeated drilling cycles
• Inside diameter of 9.25 inches provides consistent drill guidance
• Body outside diameter of 15.00 mm for precise interference fit in jig plates
• Overall length of 25.00 mm offers adequate drill guidance depth
• Non-renewable design for permanent fixture installations

Compatibility

Designed as an OEM-style replacement or new-build component for drill jigs and fixtures requiring an HM-series press fit headless bushing with a 9.25-inch inside diameter.

Installation Notes

Press fit bushings are typically installed by toolmakers or machinists using an arbor press to seat the bushing flush with the jig plate surface. Confirm the receiving hole diameter provides the correct interference fit for the bushing outside diameter before pressing. Do not hammer the bushing directly without a proper driver to avoid distortion of the bore. Once pressed in, this bushing is not designed for removal and reinstallation.
