Boneham AM00000296 Drill Bushing Hm 8.4 in Id

Product Description

The BONEHAM AM00000296 is a press fit headless drill bushing manufactured to HM industry code standards. It is used to guide drill bits and cutting tools with precision during machining operations. Made from steel, this bushing is pressed directly into a jig plate without a head flange, keeping the top surface flush. With an inside diameter of 8.4 inches, a body outside diameter of 15.00 mm, and an overall length of 12.00 mm, it is sized for applications that require consistent hole placement and repeatable accuracy across production runs. Machinists and tool-and-die professionals select this bushing for jig fixtures where a non-renewable, permanent installation is acceptable.

This bushing is suited for use in drill jig fixtures found in machine shops, fabrication facilities, and production tooling environments. It is classified as a non-renewable bushing, meaning it is intended for permanent press fit installation rather than field-replaceable service. The HM industry code designation identifies its dimensional series, allowing it to be cross-referenced against standard jig bushing catalogs. It is appropriate for applications where the bushing will not need to be swapped out for different drill sizes during a production run.

Key Features

• Press fit installation method for permanent, stable seating in jig plate bores
• HM industry code designation for standardized dimensional cross-referencing
• Steel construction for hardness and wear resistance under repeated drilling cycles
• Headless design provides a flush top surface with the jig plate
• Inside diameter of 8.4 inches for precision drill guidance
• Non-renewable configuration suited for fixed production tooling setups

Compatibility

Designed as an OEM-style replacement or direct-fit bushing for drill jig fixtures requiring an HM-series press fit headless bushing with an 8.4-inch inside diameter.

Installation Notes

Installation is performed by machinists or tooling specialists using a press or arbor press to seat the bushing flush into a precision-bored jig plate hole. Ensure the receiving bore is clean, properly sized, and deburred before pressing to avoid damage to the bushing or jig plate. Because this is a non-renewable bushing, removal after installation is not recommended and may damage the surrounding fixture material. Always verify inside diameter clearance against the drill or tool shank before pressing the bushing into service.
