Boneham CB00001096 Press Fit Headless Drill Bushing

Product Description

The BONEHAM CB00001096 is a press fit headless drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Built to Industry Code P specifications, this bushing features a 0.25 inch inside diameter and a 0.5 inch outside diameter, with an overall length of 1 inch. Manufactured from steel and hardened to 60 to 65 HRC, it resists wear under repeated tool passes. The headless design allows it to sit flush within a jig plate, making it well suited for close-tolerance fixture work. Machinists and toolmakers are the primary installers in both production and maintenance shop environments.

This bushing is used in drill jig fixtures across manufacturing, metalworking, and maintenance-repair-operations applications. The press fit installation method holds the bushing securely in a mating bore without a locking head or retaining screw, keeping the fixture profile low. It is appropriate for both light-production and high-volume drilling setups where repeatable hole location is critical. The counterbored body accommodates tool shanks or chip clearance as needed, and the ANSI-standard dimensions ensure interchangeability with other ANSI-compliant jig components.

Key Features

• Press fit installation method — no locking hardware required
• Headless design sits flush in jig plate for low-profile fixtures
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Inside diameter tolerance of plus 0.0001 to plus 0.0004 inches for tight tool guidance
• Counterbored body for tool shank or chip clearance
• Conforms to ANSI standards for drop-in interchangeability

Compatibility

Designed as an ANSI-standard press fit headless drill bushing (Industry Code P) for use in drill jig fixtures requiring a 0.25 inch ID and 0.5 inch OD bushing seat.

Installation Notes

Press fit bushings are installed by machinists or toolmakers using an arbor press or hydraulic press — never drive with a hammer, as uneven force can crack the jig plate or distort the bushing bore. The mating hole in the jig plate must be machined to the appropriate interference fit tolerance to achieve proper retention. Always de-burr and clean the receiving bore before pressing the bushing in. Verify tool clearance and chip evacuation path before beginning production runs.
