Boneham AM00000152 Drill Bushing Hm 4.4 Inches Id

Product Description

The BONEHAM AM00000152 is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Classified under industry code HM, this bushing features an inside diameter of 4.4 inches, a body outside diameter of 8.00 millimeters, and an overall length of 12.00 millimeters. Constructed from steel, it provides the hardness and wear resistance required for repetitive drilling operations. The headless design allows the bushing to sit flush within the jig plate. This component is installed without a locking collar and is not designed for renewable replacement. Machinists, toolmakers, and fixture builders are the primary users of this part.

This bushing is suited for use in drill jigs, fixture plates, and precision tooling setups where accurate hole location and consistent tool guidance are required. The press fit installation method means the bushing is driven into a machined hole in the jig body and held in place by interference fit. It is appropriate for production environments where the same jig plate is used repeatedly across a single part family or operation. The steel construction handles the demands of high-cycle drilling without significant wear to the bore.

Key Features

• HM industry code classification for standard headless press fit drill bushing applications
• Inside diameter of 4.4 inches for precise cutting tool guidance
• Body outside diameter of 8.00 millimeters for consistent jig plate fitment
• Overall bushing length of 12.00 millimeters
• Steel construction provides hardness and durability under repeated drilling cycles
• Non-renewable design — permanently pressed into the jig plate

Compatibility

Designed as an OEM-style replacement or new-installation press fit headless drill bushing for jig and fixture tooling applications using HM-classified components.

Installation Notes

Installation is performed by toolmakers or machining professionals using an arbor press or similar interference-fit pressing equipment. The receiving hole in the jig plate must be machined to the correct tolerance for press fit installation before driving the bushing into position. Power down all machinery and secure the workpiece before pressing the bushing into the fixture. Do not attempt to remove and reinstall this bushing, as it is a non-renewable design and the fit may be compromised by removal.
