Boneham AM00000068 Hm Drill Bushing 19.5 Inch Id

Product Description

The BONEHAM AM00000068 is a press fit headless drill bushing conforming to the HM industry code standard. It is designed to guide drill bits and other cutting tools with precision during machining and fabrication operations. The bushing is manufactured from steel, providing the hardness and wear resistance required for repeated tool guidance in production environments. With a 19.5-inch inside diameter and a non-renewable, fixed-installation design, this bushing is pressed directly into a jig plate and remains in place for the life of the fixture. Machinists and tool-and-die professionals are the typical installers.

This bushing is suited for use in drill jigs and fixture plates in both production and job-shop machining environments. The headless profile keeps the bushing flush with the jig plate surface, which is important in close-clearance applications where a flanged head would interfere with workpiece positioning or clamping. It is commonly installed in metalworking and fabrication shops handling medium to large bore drilling operations requiring consistent hole location accuracy.

Key Features

• HM industry code classification for standardized fitment in compatible jig plates
• Press fit installation method — no locking hardware required
• Headless design sits flush with jig plate surface
• Steel construction for wear resistance and long service life
• Non-renewable design intended for permanent fixture installation

Compatibility

Designed as an OEM-style replacement or original-fit component for drill jig fixtures requiring an HM-series press fit headless bushing with a 19.5-inch inside diameter.

Installation Notes

Installation is performed by pressing the bushing into a prepared jig plate bore using an arbor press or hydraulic press. The receiving bore should be machined to the appropriate interference-fit tolerance before pressing to prevent bushing damage or misalignment. Power down all associated machinery before handling or pressing bushings into fixtures. Once pressed in, this bushing is not intended for removal and reuse.
