Boneham PT2812HX Headless Drill Bushing 9/32 in Id Steel

Product Description

The BONEHAM PT2812HX is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Machined from steel and hardened to 60 to 65 HRC, this bushing provides consistent bore alignment and long service life under repeated drilling cycles. The headless profile sits flush with the jig plate surface, making it well suited for applications where a protruding head would interfere with workpiece positioning. The 9/32 inch inside diameter accepts matching drill shanks within a tight tolerance of plus 0.0001 to plus 0.0005 inches, ensuring accurate hole placement across production runs.

This bushing is used in metalworking, toolmaking, and manufacturing environments where repeatable hole location is critical. The press fit installation method secures the bushing permanently into a mating liner or jig plate bore. It is a non-renewable type, intended for fixed installation rather than field replacement during a job run. Typical installers include tool and die makers, fixture builders, and precision machinists working in job shops or production facilities.

Key Features

• Headless design sits flush with jig plate surface to avoid workpiece interference
• Press fit installation for permanent, secure seating in liner or plate bore
• Steel construction hardened to 60 to 65 HRC for wear resistance
• Inside diameter tolerance of plus 0.0001 to plus 0.0005 inches for precise drill guidance
• Meets ANSI standards for drill bushing dimensions and tolerances
• Bushing Industry Code P for straightforward cross-reference sourcing

Compatibility

Designed as an OEM-style fixed drill bushing for use in jig plates and fixture assemblies requiring a 9/32 inch bore guide with a 7/16 inch outside diameter press fit installation.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press to drive the bushing into a precisely reamed mating bore. The receiving hole must be reamed to the correct interference fit dimension before pressing to avoid bushing damage or bore distortion. Power to any associated machine must be locked out and tagged out before servicing or replacing fixture components. The bushing is not renewable and should be considered permanent once pressed into place.
