Built from solid carbide and coated with a dual TiAlCr and TiSi finish, this bit delivers the hardness and thermal resistance required for cutting cast iron, stainless steel, carbon steel, and high-temperature alloys. The 135-degree split-point geometry reduces walking on entry and lowers thrust force compared to conventional 118-degree points. At 5.3543 inches overall length with a 3.1496-inch flute, it fits standard jobber-length drill chucks and is suited for CNC machining centers, drill presses, and manual machine tool operations. Coolant-through capability supports high-speed runs in production settings.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for metal cutting applications across a range of workpiece materials classified under ISO material codes K (cast iron), M (stainless steel), P (steel), and S (high-temperature alloys). The MDW-HGS series is engineered for use in CNC and manual drilling operations where tool life and hole quality in difficult materials are priorities. It is typically selected by machinists, toolroom technicians, and production floor operators working with ferrous and stainless workpieces. The straight-cylindrical shank and 0.3906-inch shank diameter seat securely in standard collet chucks and drill holders without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and heat resistance for metal cutting applications\u003c\/li\u003e\n  \u003cli\u003eDual TiAlCr and TiSi coating extends tool life in high-friction ferrous and stainless materials\u003c\/li\u003e\n  \u003cli\u003e135-degree drill point angle reduces entry thrust and minimizes workpiece damage\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery for high-speed and deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration improves chip evacuation and core strength\u003c\/li\u003e\n  \u003cli\u003eMDW-HGS series, 5xD flute-to-diameter ratio, with h8 diameter tolerance for precision fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with cast iron, stainless steel, steel, and high-temperature alloy workpieces.

Ensure the collet or chuck is clean and free of debris before seating the shank to maintain concentricity and prevent runout. Verify that the machine spindle speed and feed rate are appropriate for the workpiece material and drill diameter before beginning the cut. Do not exceed the tool's rated operating parameters for coolant pressure or spindle RPM.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 5.3543 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.1496 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3906 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.2047 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0777 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlCr and TiSi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel, High-Temperature Alloys\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MDW-HGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Metal Cutting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: U103727\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51731476513074,"sku":"U103727","price":280.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d6bae2d28c4cec425003151fc2851f8.jpg?v=1788731578","url":"https:\/\/voomisupply.com\/products\/sumitomo-u103727-3-8-inch-solid-carbide-drill-bit-mdw-hgs","provider":"Voomi Supply","version":"1.0","type":"link"}
