Boneham CB00001154 Press Fit Headed Drill Bushing Type H

Product Description

The BONEHAM CB00001154 is a Type H press fit headed drill bushing designed to guide drill bits with precision in jig and fixture applications. It features a 0.125 inch inside diameter, a 0.25 inch body outside diameter, and a 0.5 inch length under the head. Constructed from hardened steel with a hardness rating of 60 to 65 HRC, this bushing resists wear over extended production runs. The headed design provides a positive stop against the jig plate surface, maintaining consistent drill depth and alignment. The inside diameter tolerance of +0.0001 to +0.0004 inches ensures accurate hole location for repetitive drilling operations.

This bushing is suited for use in drill jigs and production fixtures across metalworking, machining, and fabrication environments. It is pressed directly into the jig body and is not intended to be removed and replaced during normal service. Typical applications include high-volume drilling operations where consistent hole placement is critical. The compact 0.25 inch body OD and 0.5 inch working length make it well suited for jigs with limited plate thickness or closely spaced hole patterns. Installation is performed by machinists or tool and die professionals in shop environments.

Key Features

• Type H headed design provides a positive stop flush against the jig plate
• Hardened steel construction rated 60 to 65 HRC for long service life in high-cycle operations
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise drill guidance
• Press fit installation - no locking mechanisms or additional hardware required
• Meets ANSI standards for drill bushing geometry and tolerances
• Non-renewable design intended for permanent installation in the jig body

Compatibility

Designed as an OEM-style replacement or direct installation component for drill jigs and fixtures requiring a Type H press fit headed bushing with a 0.125 inch inside diameter per ANSI standards.

Installation Notes

Press fit bushings are installed by machinists using an arbor press or hydraulic press - never drive them in with a hammer, as uneven force can damage the bore or distort the bushing. The receiving hole in the jig plate must be machined to the correct interference fit tolerance before installation. Once pressed in, this bushing is not designed for removal; use a renewable liner bushing system if frequent replacement is anticipated. Always de-energize and lock out any machine tool before servicing or replacing jig components.
