Boneham AM00000189 Drill Bushing Hm 5.4 in Id Steel

Product Description

The BONEHAM AM00000189 is a press fit headless drill bushing with an HM industry code, designed to guide drill bits and cutting tools with precision in jig and fixture applications. Manufactured from steel, this bushing features an inside diameter of 5.4 inches, a body outside diameter of approximately 0.394 inches (10.00 mm), and an overall length of approximately 0.630 inches (16.00 mm). The headless design allows the bushing to sit flush within the jig plate, making it well suited for close-tolerance drilling operations. Machinists, tool-and-die makers, and precision fabricators install this type of component as part of a drill jig assembly.

This drill bushing is used in metalworking, machining, and fabrication environments where repeatable hole location accuracy is required. It is pressed directly into a hardened or unhardened jig plate and is not designed for removal and replacement during production runs, as indicated by its non-renewable designation. Typical applications include production drilling fixtures in job shops, manufacturing cells, and toolroom setups where consistent hole placement is critical across multiple workpieces.

Key Features

• Press fit installation method for secure, permanent seating in jig plates
• HM industry code designation for standard headless style identification
• 5.4-inch inside diameter to accommodate corresponding drill or cutting tool shank
• Steel construction for durability in repetitive drilling operations
• Headless design allows flush mounting with the jig plate surface
• Non-renewable configuration — intended as a fixed, permanent installation

Compatibility

Designed as an OEM-style press fit headless drill bushing conforming to HM industry standards, suitable for use in standard drill jig plates and fixtures requiring a press fit bushing of this bore size.

Installation Notes

Installation of this bushing is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush and square within the jig plate bore. The mating jig plate bore must be machined to the appropriate press fit tolerance for the bushing outside diameter before installation. Once pressed in, this bushing is not intended for removal without potential damage to the host plate. Always verify concentricity and perpendicularity of the bushing after pressing to maintain drilling accuracy.
