Boneham AM00000322 Hm Drill Bushing 9.1 Inch Id Steel

Product Description

The BONEHAM AM00000322 is a press fit headless drill bushing designed to guide drill bits with precision in jig and fixture applications. Built to HM industry standards, this bushing features a 9.1-inch inside diameter and is manufactured from steel for durability under repeated drilling cycles. It installs without a locking collar, seating flush within the jig plate for a clean, low-profile setup. Machinists and toolmakers rely on this type of bushing to maintain accurate hole placement across production runs. The headless design is preferred when clearance above the jig plate is limited or when a smooth top surface is required.

This bushing is suited for use in metal fabrication shops, machine shops, and production environments where drill jigs require consistent hole guidance. It fits into jig plates or fixture bodies where a press fit installation method is specified. The HM industry code designates the dimensional standards this bushing conforms to, making it a direct fit for tooling built to those specifications. With a body outside diameter of approximately 0.591 inches (15.00 mm) and an overall length of approximately 0.984 inches (25.00 mm), it is sized for compact fixture work.

Key Features

• HM industry code designation for standardized dimensional compatibility in drill jig tooling
• Press fit installation method seats the bushing securely without a locking ring or collar
• Steel construction provides wear resistance through repeated drill passes
• Headless design allows flush seating in jig plate for low-profile applications
• Non-renewable style for permanent press-in fixture use

Compatibility

Designed as an OEM-style replacement or original-fit component for drill jigs and fixtures built to HM press fit headless bushing standards.

Installation Notes

Press fit bushings are typically installed by toolmakers or machinists using an arbor press to seat the bushing evenly into the jig plate bore. Ensure the receiving bore is dimensioned correctly for an interference fit before pressing. Do not use impact tools to drive the bushing, as this can damage the bore or distort the bushing. Verify alignment before pressing fully to prevent cocking in the bore.
