Boneham AM00000678 Press Fit Headless Drill Bushing Pm

Product Description

The BONEHAM AM00000678 is a press fit headless drill bushing in industry code PM, designed to guide drill bits with precision in jig and fixture applications. Made from steel, this bushing installs without a retaining head, seating flush within a tooling plate or drill jig for a clean, low-profile fit. With an inside diameter of 7.75 inches, a body outside diameter of 12.00 millimeters, and an overall length of 20.00 millimeters, it delivers accurate hole location and consistent repeatability across production runs. Machinists and toolmakers specify this bushing for applications where dimensional control and durability are critical.

This bushing is suited for use in manufacturing and production environments where drill jigs are employed to guide cutting tools into precise locations. Press fit headless bushings in the PM series are a standard choice for renewable and fixed jig setups that require a flush surface on the tooling face. They are installed in tooling plates, fixture bodies, and jig components across metalworking, fabrication, and general machining operations. The non-renewable design makes this a fixed installation, appropriate where the bushing location is not expected to require regular changeout.

Key Features

• Press fit installation seats the bushing securely without threading or retaining hardware
• Headless design provides a flush, low-profile seating surface in the tooling plate
• PM industry code classification for standard jig bushing interchangeability
• Steel construction for durability and wear resistance in repetitive drilling operations
• Non-renewable fixed design suited for permanent jig setups
• Inside diameter of 7.75 inches for precise drill bit guidance

Compatibility

Designed as an OEM-style replacement or direct specification fit for standard PM-series press fit headless drill bushing applications in steel tooling plates and drill jigs.

Installation Notes

Installation is performed by toolmakers or machinists using a press to drive the bushing into a prepared hole in the jig or fixture body. Power down all equipment in the work area before pressing or removing bushings from any active fixture. Ensure the receiving bore is machined to the correct interference fit tolerance before pressing to avoid damage to the bushing or tooling plate. Do not use an arbor press or hammer without proper support to prevent misalignment during installation.
