It produces a 1.3465-inch (34.20 mm) spotface diameter with a 15-degree seal angle, creating the precise seating surface required for O-ring face seal fittings on M27x2.0 metric fine threaded ports. The four-flute straight flute geometry and bright finish provide clean, accurate cuts in steel and other common hydraulic manifold materials. Machinists and hydraulic system fabricators use this tool to ensure leak-free fitting installations in high-pressure fluid power assemblies.\u003c\/p\u003e\u003cp\u003eThis porting tool is intended for use on M27x2.0 metric fine thread port applications found in hydraulic manifolds, cylinders, valves, and related fluid power components. It is suited for both production machining environments and field or maintenance shop repair work where port faces require reconditioning or initial preparation. The reamer pilot guides the tool concentrically within the existing port bore, ensuring consistent spotface alignment across repeated operations. Industrial machinists and hydraulic system technicians are the primary users of this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.3465-inch (34.20 mm) spotface diameter for M27x2.0 O-ring face seal ports\u003c\/li\u003e\n\u003cli\u003e15-degree seal angle conforming to ISO 6149-1 and SAE J2244-1 standards\u003c\/li\u003e\n\u003cli\u003eReamer pilot type with 0.9843-inch minimum pilot diameter and 0.7402-inch pilot length for concentric alignment\u003c\/li\u003e\n\u003cli\u003eFour straight flutes for smooth, accurate material removal\u003c\/li\u003e\n\u003cli\u003e3\/4-inch shank diameter with 2.1200-inch shank length for standard toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eBright (uncoated) finish suitable for general-purpose hydraulic port machining\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for machining O-ring face seal port spotfaces on M27x2.0 metric fine threaded hydraulic ports per ISO 6149-1 and SAE J2244-1 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is used by machinists in milling machines, drill presses, or CNC machining centers with appropriate toolholding for a 3\/4-inch shank. Ensure the workpiece is securely fixtured and the hydraulic system or component is fully depressurized and de-energized before any machining operation. Use appropriate cutting fluid for the workpiece material to maintain tool life and surface finish quality. Follow applicable shop safety standards and manufacturer feed and speed recommendations for reamer-type porting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpotface Diameter\u003c\/strong\u003e: 1.3465 inches (34.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Thread Size\u003c\/strong\u003e: M27x2.0 metric fine\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: 0.9843 inches (25.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pilot Diameter\u003c\/strong\u003e: 1.1595 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Length\u003c\/strong\u003e: 0.7402 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.9400 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.1200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.8200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 6149-1, SAE J2244-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIdentification Groove\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 6149-M27X2.0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51962928333106,"sku":"6149-M27X2.0","price":387.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/147609a3282d3bb20afdb53c515de853.jpg?v=1789948048","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-6149-m27x2-0-porting-tool-reamer","provider":"Voomi Supply","version":"1.0","type":"link"}
