Boneham CB00001084 Headless Drill Bushing 7/32 in Id

Product Description

The BONEHAM CB00001084 is a press fit headless drill bushing in industry code P, designed to guide cutting tools with precision in jig and fixture applications. Machined from steel and hardened to 60 to 65 HRC, this bushing delivers consistent bore alignment and long service life under repeated use. The headless profile sits flush with the jig plate surface, making it well suited for applications where a protruding head would interfere with workpiece seating. Inside diameter is 7/32 inches with a tolerance of plus 0.0001 to plus 0.0004 inches, ensuring a controlled fit around standard drill sizes. Machinists and toolmakers are the primary installers.

This bushing is used in drill jigs, fixtures, and production tooling setups where repeatable hole location is required. The 3/8 inch outside diameter and 1 inch overall length suit it to moderate-depth jig plates in both prototype and production environments. It is pressed directly into a reamed hole in the jig body without a locking collar or retaining hardware, making it a permanent, non-renewable installation. Typical applications include metalworking shops, maintenance repair operations, and manufacturing toolrooms.

Key Features

• Headless design sits flush with jig plate surface to avoid workpiece interference
• Steel construction hardened to 60 to 65 HRC for wear resistance under repeated drilling cycles
• Inside diameter tolerance of plus 0.0001 to plus 0.0004 inches for precise tool guidance
• Press fit installation into a reamed hole — no collar or locking hardware required
• Meets ANSI standards for drill bushing dimensions and tolerances
• Non-renewable design for permanent fixture installations

Compatibility

Designed as an OEM-style replacement or standard tooling component for drill jigs and fixtures requiring a press fit headless bushing with 7/32 inch ID and 3/8 inch OD per ANSI specifications.

Installation Notes

Installation is performed by toolmakers or machinist technicians using an arbor press. The mating hole in the jig plate must be reamed to the appropriate interference fit diameter before pressing the bushing into place. Once pressed in, this bushing is not intended for removal and reuse. Verify bore alignment and check the bushing for concentricity after pressing to confirm proper seating.
