It features an inside diameter of 0.277 inches (Letter J), a body outside diameter of 0.5 inches, and a length under head of 0.25 inches. The head outside diameter measures 39\/64 inches and the head height is 7\/32 inches. This bushing is pressed directly into a drill jig plate without the need for a liner bushing, making it a fixed, non-renewable installation. Machinists and toolmakers install these bushings to guide drill bits, reamers, and other cutting tools with precision during production runs.\u003c\/p\u003e\u003cp\u003eType H headed drill bushings like the H324HU are suited for jig plates where the head must seat flush or above the jig surface to locate the bushing axially. They are used in metalworking shops, tool rooms, and production machining environments where consistent hole location is required across repeated operations. This bushing is non-renewable and intended for permanent or long-term fixture installations where the bushing body is pressed directly into a hardened or unhardened jig plate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation — no liner bushing required\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in production machining environments\u003c\/li\u003e\n\u003cli\u003eHeaded design provides positive axial location in the jig plate\u003c\/li\u003e\n\u003cli\u003eInside diameter designation: Letter J (0.2770 inches decimal)\u003c\/li\u003e\n\u003cli\u003eNon-renewable fixed bushing — designed for permanent press fit installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Type H press fit headed drill bushing for use in drill jigs and machining fixtures requiring a 0.5 inch body outside diameter and 0.277 inch inside diameter tool guide.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by pressing the bushing into a prepared hole in the jig plate using an arbor press or similar pressing equipment.
