Boneham AM00000052 Drill Bushing Hm 16.5 in Id

Product Description

The BONEHAM AM00000052 is a press fit headless drill bushing in the HM industry code series, designed to guide cutting tools with precision during drilling, reaming, and boring operations. Manufactured from steel with a hardness of 60 to 65 HRC, this bushing provides the wear resistance required in production jig and fixture work. The 16.5-inch inside diameter accommodates large-bore tooling applications, and the press fit installation method locks the bushing securely into a jig plate without a retaining head. It is intended for machinists, tool and die makers, and fixture builders working to ANSI standards.

This bushing is suited for use in drill jigs and tooling fixtures in industrial machining environments. The HM industry code designates its headless, press-fit form, which is appropriate for applications where a flush surface or minimal fixture height is required. The non-renewable design means it is intended to be pressed into the jig plate permanently rather than swapped during a production run. This makes it a practical choice for high-volume drilling setups where tool guidance accuracy is critical and bushing replacement is not part of the routine workflow.

Key Features

• Press fit installation method — no retaining head, seats flush in jig plate
• HM industry code headless bushing configuration per ANSI standards
• Steel construction hardened to 60 to 65 HRC for extended wear life
• 16.5-inch inside diameter for large-bore tool guidance
• Non-renewable design for permanent installation in production fixtures
• Inside diameter tolerance of +0.006 to +0.017 mm for consistent tool fit

Compatibility

Designed as an ANSI-standard HM series press fit headless drill bushing for use in drill jigs and machining fixtures requiring permanent, large-bore tool guidance.

Installation Notes

Installation is performed by tool and die makers or machinists using a press to seat the bushing into a prepared jig plate bore. The jig plate hole must be machined to the correct tolerance to accept the press fit outer diameter before installation. Once pressed in, the bushing is not designed for removal or replacement. Follow applicable shop safety procedures and ensure all associated machinery is locked out before working on fixtures.
