It measures 5\/8 inch (0.6250 inch) in diameter with an overall length of 7.6378 inches and a 135-degree split point angle for accurate self-centering entry. The TiAlCr and TiSi dual coating provides thermal resistance and wear protection at elevated cutting speeds. The straight-cylindrical shank and tapered web configuration support rigid tool holding and efficient chip evacuation. This bit is intended for installation and use by machinists, toolroom technicians, and skilled trades professionals working with CNC machining centers or manual drill presses.\u003c\/p\u003e\n\u003cp\u003eThe U103760 is engineered for cutting cast iron, stainless steel, carbon steel, and high-temperature alloys, corresponding to ISO workpiece material codes K, M, P, and S. Its 5xD flute-to-diameter ratio and 5.0394-inch flute length make it well suited for drilling deeper holes in production environments where tool life and hole quality are critical. The coolant-through design supports internal coolant delivery, making it effective in high-feed or extended-reach drilling operations on machining centers equipped with through-spindle coolant systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eTiAlCr and TiSi dual coating for high-temperature resistance and reduced flank wear\u003c\/li\u003e\n  \u003cli\u003e135-degree drill point angle for accurate entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design compatible with through-spindle coolant delivery systems\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration promotes chip breaking and evacuation in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with h8 diameter tolerance for consistent tool holder fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe U103760 belongs to the SUMITOMO MDW-HGS series and is suited for use in standard 5\/8 inch collet chucks, hydraulic tool holders, or shrink-fit holders compatible with a straight-cylindrical shank. It is rated for cutting cast iron, stainless steel, steel, and high-temperature alloy materials (ISO codes K, M, P, S).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis drill bit should be installed and operated by qualified machinists or toolroom technicians familiar with carbide cutting tool handling. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Carbide tooling is brittle — avoid side loading, interrupted cuts without proper programming, or dropping the bit on hard surfaces. Verify that through-spindle coolant pressure and flow rate are within the machine and tooling specifications before engaging the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.6378 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.0394 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.5984 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: 0.1294 inches (3.29 mm)\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel, High-Temperature Alloys (ISO K, M, P, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Metal Cutting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MDW-HGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7.64 inches L x 0.88 inches W x 0.88 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 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: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: U103760\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51730499273010,"sku":"U103760","price":734.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/001b15f99d6342e55d4cd6cb4c20fe91.jpg?v=1788718545","url":"https:\/\/voomisupply.com\/products\/sumitomo-u103760-jobber-drill-bit-5-8-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
