Boneham AM00000326 Press Fit Headless Drill Bushing Hm

Product Description

The BONEHAM AM00000326 is a press fit headless drill bushing classified under industry code HM. It is designed to guide drill bits and other cutting tools with precision during machining and fabrication operations. The bushing installs without a head, keeping a flush or sub-flush profile in jig plates and fixture assemblies. Constructed from steel, it provides the hardness and wear resistance required for repetitive drilling cycles. With an inside diameter of 9.2 inches, it is sized for high-volume production environments and heavy-duty jig tooling applications. Machinists, tool-and-die makers, and fixture builders are the primary installers of this component.

This drill bushing is suited for use in drill jigs, fixture plates, and precision tooling setups in industrial and manufacturing environments. It is pressed directly into a close-tolerance hole in the jig body, eliminating the need for a locking collar. The HM industry code designation identifies its dimensional standards, making it straightforward to specify as a direct replacement or new installation in conforming jig designs. Its non-renewable construction means it is intended as a permanent installation once pressed into place.

Key Features

• Press fit installation method for secure, permanent seating in jig plates
• Headless design provides a flush profile in fixture assemblies
• HM industry code classification for standardized dimensional reference
• Steel construction for hardness and durability in high-cycle drilling operations
• Non-renewable design intended for permanent installation

Compatibility

Designed as an OEM-style replacement or new installation component for drill jigs and fixture assemblies conforming to HM-series headless press fit bushing dimensional standards.

Installation Notes

Installation is typically performed by a machinist or tool-and-die maker using an arbor press or hydraulic press to seat the bushing into a pre-machined, close-tolerance hole. The jig or fixture should be fully powered down and secured before pressing begins. Do not use impact tools to drive the bushing, as this can cause damage to the bushing bore or the jig body. Verify hole tolerance and surface finish in the jig plate before installation to ensure proper press fit retention.
