Boneham SP00004707 Press Fit Headless Drill Bushing

Product Description

The BONEHAM SP00004707 is a press fit headless drill bushing classified under industry code P. It is designed to guide drill bits and other cutting tools with precision during machining and fabrication operations. The bushing features a 17/32 inch inside diameter and a 7/8 inch body outside diameter, with an overall length of 5/8 inch. Constructed from steel, it provides the hardness and wear resistance required for repetitive production drilling. Installation is permanent — the headless design allows the bushing to sit flush within the jig plate. Machinists, toolmakers, and fixture builders are the primary installers of this component.

This bushing is suited for use in drill jigs and tooling fixtures in light to medium industrial machining environments. The headless press fit style is commonly used when a flush surface is required and bushing replacement is not anticipated during the service life of the fixture. It is appropriate for use in both manual drill press setups and CNC fixture plates where guided hole location accuracy is critical.

Key Features

• Press fit installation method for permanent, secure seating in jig plate bores
• Headless design allows flush mounting within the fixture surface
• 17/32 inch inside diameter for precise drill guidance
• 7/8 inch body outside diameter for positive press fit retention
• 5/8 inch overall length suits standard jig plate thicknesses
• Steel construction provides hardness and resistance to wear from repeated tool passes

Compatibility

Designed as an OEM-style replacement or new-installation press fit headless drill bushing for use in standard drill jig fixtures requiring a P-series bushing with a 17/32 inch inside diameter and 7/8 inch outside diameter.

Installation Notes

Press fit bushings are installed by toolmakers or machinists using an arbor press or hydraulic press to drive the bushing into a precision-reamed hole in the jig plate. The receiving bore must be machined to the appropriate interference fit tolerance before installation. Do not hammer the bushing directly without a proper driver, as this can damage the bushing bore or distort the outer diameter. Once pressed in, this bushing is not intended to be removed or replaced.
