It combines a reamer pilot with a spotface cutter in a single tool, allowing technicians to size the pilot bore and face the port seat in one operation. The RPT-4 features a 0.496-inch spotface diameter, a 0.275-inch minimum pilot diameter, and a 0.340-inch maximum pilot diameter. Overall length is 4 inches with a 0.5-inch shank diameter. The bright, uncoated solid carbide construction provides rigidity and edge retention on steel and aluminum tube port work.\u003c\/p\u003e\n\u003cp\u003eThis tool is used in hydraulic and pneumatic system fabrication and repair where tube fittings require a clean, flat port face and a correctly sized pilot bore. It is suited for shop or field use by hydraulic technicians, aerospace maintenance crews, and industrial plumbing specialists working with dash-4 tube connections. The straight flute geometry and 21-degree seal angle make it appropriate for producing consistent port geometry in tube end work on compatible workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpotface diameter of 0.496 inches for precise port face preparation\u003c\/li\u003e\n  \u003cli\u003eCompatible with 1\/4-inch OD tube dash-4 connections\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and long tool life\u003c\/li\u003e\n  \u003cli\u003e3 straight flutes with 21-degree seal angle for clean seat geometry\u003c\/li\u003e\n  \u003cli\u003eReamer-style pilot with 0.275-inch minimum and 0.340-inch maximum pilot diameter\u003c\/li\u003e\n  \u003cli\u003eUNJF thread type compatibility for aerospace and hydraulic fitting standards\u003c\/li\u003e\n  \u003cli\u003eBright finish with no coating for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with dash-4 tube fittings with 1\/4-inch outside diameter tubing requiring UNJF port preparation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and operated by machinists or hydraulic system technicians using a drill press, milling machine, or appropriate hand-held power tool with a 1\/2-inch shank chuck. Secure the workpiece firmly before operation and ensure the pilot bore is free of burrs before engaging the reamer. Do not exceed the tool's maximum pilot diameter of 0.340 inches when selecting pre-drilled pilot holes. Follow all applicable shop safety and hydraulic system service procedures when working on pressurized systems.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpotface Diameter\u003c\/strong\u003e: 0.496 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter Compatibility\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Dash Number\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Type\u003c\/strong\u003e: Reamer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Pilot Diameter\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pilot Diameter\u003c\/strong\u003e: 0.340 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Length\u003c\/strong\u003e: 0.4015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Angle\u003c\/strong\u003e: 21 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNJF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIdentification Groove\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWorkpiece Compatibility\u003c\/strong\u003e: Tubes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: RPT-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52124355232050,"sku":"RPT-4","price":294.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/acdffc92ead302a4d7391b23fb106fdb.jpg?v=1790086751","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-rpt-4-porting-tool-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
