Boneham PT364IW Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM PT364IW is a press fit headless drill bushing used to guide drill bits and cutting tools with precision during machining and fabrication operations. Manufactured from steel, this bushing is pressed directly into a jig plate or fixture without a locking head, keeping the top surface flush. The inside diameter measures 0.332 inches with a tolerance of +0.0001 to +0.0005 inches, the body outside diameter is 9/16 inches, and the overall length is 1/4 inch. It carries industry bushing code P and is suited for applications where a renewable bushing is not required.

This bushing is used in drill jig fixtures on production floors and job shops where consistent hole location accuracy is critical. It is appropriate for light- to medium-duty drilling operations in metalworking, tool and die, and general machining environments. The headless design is selected when flush seating is required and the bushing is intended to remain permanently in the fixture. Machinists, tool makers, and fixture builders typically install this component.

Key Features

• Press fit installation method — no head flange, seats flush with fixture surface
• Inside diameter of 0.332 inches with tight tolerance of +0.0001 to +0.0005 inches for accurate tool guidance
• Body outside diameter of 9/16 inches and overall length of 1/4 inch
• Steel construction for wear resistance in repetitive drilling applications
• Non-renewable design — intended as a permanent press-in bushing
• Bushing industry code P for standard catalog cross-reference

Compatibility

Designed as a standard press fit headless drill bushing for use in drill jig fixtures where an industry code P bushing with a 0.332 inch inside diameter and 9/16 inch outside diameter is specified.

Installation Notes

Installation requires a hydraulic or arbor press to seat the bushing flush into a properly sized hole in the jig plate — do not drive with a hammer, as this can damage the bushing bore or distort the fixture. Ensure the receiving hole in the fixture meets the required press fit tolerance for the 9/16 inch outside diameter before installation. Because this is a non-renewable bushing, removal will likely damage the part or the fixture, so confirm placement before pressing. A licensed machinist or tool maker should verify fixture tolerances and alignment per applicable shop standards before use.
