Boneham AM00000656 Press Fit Drill Bushing 7.1 in Id

Product Description

The BONEHAM AM00000656 is a press fit headless drill bushing manufactured from steel and designed to guide drill bits with precision in fixed jig applications. This bushing carries the industry code PM and features an inside diameter of 7.1 inches with an overall bushing length of 16.00 millimeters. It installs without a head flange, seating flush with the jig plate surface for clean, unobstructed drilling. Machinists and tool-and-die professionals use this style of bushing where a low-profile installation is required and where the bushing is intended to remain permanently in place rather than be swapped out between operations.

This headless drill bushing is suited for use in drill jigs across general metalworking, production machining, and maintenance repair operations. Its press fit installation method means no additional retaining hardware is needed once the bushing is driven into the jig plate bore. The steel construction provides the hardness and wear resistance required for repetitive drilling cycles. This part ships as a single unit and is appropriate for both new jig builds and replacement of worn bushings in existing fixtures.

Key Features

• Press fit installation seats the bushing permanently without retaining rings or screws
• Headless design sits flush with jig plate surface for unobstructed drill access
• Steel construction provides hardness and durability for high-cycle drilling operations
• Inside diameter of 7.1 inches for precise drill bit guidance
• Overall bushing length of 16.00 millimeters accommodates standard jig plate thicknesses
• Non-renewable design intended as a permanent fixture component

Compatibility

Designed as a permanent press fit replacement or new-install headless drill bushing for steel drill jigs conforming to PM industry code specifications.

Installation Notes

Installation is performed by pressing the bushing into a correctly sized bore in the jig plate using an arbor press or hydraulic press. The jig plate bore must be machined to the appropriate interference fit tolerance before installation. Do not drive the bushing with a hammer directly against the bore face, as this may damage the bushing ID or distort the plate. This work is typically performed by machinists or tool-and-die technicians in a shop environment.
