Boneham AM00000329 Drill Bushing Hm 9.3 in Id Steel

Product Description

The BONEHAM AM00000329 is a press fit headless drill bushing classified under industry code HM, designed to guide drill bits with precision during machining and fabrication operations. Manufactured from steel, this bushing features a 9.3-inch inside diameter and is installed directly into a jig plate or fixture without a head flange, keeping the bushing flush with the workpiece surface. It is a non-renewable type, meaning it is pressed permanently into the fixture rather than designed for frequent field replacement. Machinists, tool and die makers, and fabrication professionals use this bushing to maintain accurate hole location and extend the working life of drill jigs.

This bushing is suited for use in drill jig fixtures across general machining, metalworking, and manufacturing applications. Its steel construction provides the hardness and wear resistance needed in production environments where drill bits must be guided repeatedly through the same location. The HM industry code designation identifies its dimensional standard, allowing straightforward cross-referencing when sourcing replacements or designing new fixtures.

Key Features

• Press fit installation method seats bushing permanently and securely in jig plate
• HM industry code designation for standardized dimensional compatibility
• 9.3-inch inside diameter for precise drill bit guidance
• Steel construction for durability and wear resistance in production use
• Headless design sits flush with fixture surface, no flange interference
• Non-renewable design for permanent fixture installations

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for steel drill jig fixtures requiring an HM-series press fit headless bushing with a 9.3-inch inside diameter.

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 flush into a precision-reamed hole in the jig plate. Power down and secure all machinery before pressing the bushing into position. Do not hammer the bushing directly, as this can damage the bore or distort the outer diameter. Verify hole tolerance in the fixture plate matches the bushing outside diameter specification before pressing.
