Boneham AM00000219 Press Fit Headless Drill Bushing Hm

Product Description

The BONEHAM AM00000219 is a press fit headless drill bushing in the HM industry classification, designed to guide drill bits with precision in jig and fixture applications. Manufactured from steel, this bushing is pressed directly into a jig plate without a head flange, keeping the top surface flush for close-tolerance drilling operations. It features an inside diameter of 6.2 inches, a body outside diameter of approximately 0.472 inches, and an overall length of approximately 0.630 inches. Licensed machinists, tool and die technicians, and precision metalworking professionals install this type of bushing in production drilling setups where repeatable hole placement is required.

This drill bushing is suited for use in fixed jig plate installations where the bushing is not intended to be removed or replaced during normal production cycles. The headless press fit design is common in high-volume drilling fixtures where a flush top surface is necessary to allow workpiece clearance or nesting. It is non-renewable, meaning it is intended to remain permanently seated in the jig plate once installed. Applications include production machining, fabrication shops, and toolroom fixture builds across metalworking industries.

Key Features

• Press fit installation method seats the bushing flush with the jig plate surface
• HM industry code classification for standardized toolroom and fixture compatibility
• Inside diameter of 6.2 inches for precise drill bit guidance
• Steel construction for durability in production drilling environments
• Non-renewable design for permanent fixture applications
• Headless profile eliminates flange interference on close-clearance workpieces

Compatibility

Designed as an OEM-style press fit headless drill bushing for use in steel jig plates and drilling fixtures conforming to HM industry code dimensions.

Installation Notes

Installation is performed by machinists or toolroom technicians using an arbor press or hydraulic press to seat the bushing into a precision-reamed hole in the jig plate. The receiving hole in the jig plate must be sized to the correct press fit tolerance for the bushing outside diameter before installation. Once pressed in, the bushing is not designed for removal. Ensure the fixture is fully secured and the work surface is clear before pressing the bushing into position.
