Boneham P165DM Press Fit Headless Drill Bushing

Product Description

The BONEHAM P165DM is a press fit headless drill bushing manufactured from steel, designed to guide cutting tools with precision during drilling operations. With an inside diameter of 0.111 inches and a body outside diameter of 0.25 inches, this bushing provides accurate tool guidance in jig and fixture applications. The headless profile allows flush or sub-flush installation where protruding heads would interfere with workpiece clearance or fixture design. Inside diameter tolerance is held to +0.0001 to +0.0004 inches, ensuring consistent hole location across repeated drilling cycles. This is a non-renewable fixed bushing intended for permanent press fit installation.

The P165DM is suited for use in drill jigs, fixture plates, and tooling assemblies in metalworking, machining, and precision fabrication environments. Its compact 0.3125-inch overall length makes it appropriate for thin fixture plates and close-tolerance setups where tool guidance is required without added stack height. Machinists, toolmakers, and fixture builders are the primary installers of this type of component.

Key Features

• Press fit installation — no fasteners or retaining collars required
• Headless design allows flush mounting in fixture plates and jig bodies
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance

• Non-renewable fixed bushing — intended for permanent installation
• Industry code P bushing per standard drill bushing classifications

Compatibility

Designed as an OEM-style fixed drill bushing for use in drill jigs and fixture assemblies requiring a 0.25-inch outside diameter press fit headless bushing with a 0.111-inch inside diameter bore.

Installation Notes

Installation is performed by toolmakers or machinist personnel using a press or arbor press to drive the bushing into a precision-reamed hole in the jig plate. The receiving bore must be machined to the correct interference fit tolerance before installation. Once pressed in, this bushing is not designed for removal or replacement. Ensure the fixture plate is secure and properly supported during pressing to avoid distortion or misalignment.
