The bit measures 17\/32 inch (0.5313 inches) in diameter with a 135-degree split-point tip that reduces walking and cutting force at entry. A dual-coating of TiAlCr and TiSi provides heat resistance and extended tool life at elevated cutting speeds. Overall length is 6.9291 inches, with a flute length of 4.2520 inches and a straight-cylindrical shank diameter of 0.5469 inches. This tool is intended for use by machinists and toolroom technicians working in high-volume or precision drilling applications.\u003c\/p\u003e\n\u003cp\u003eThe U103748 is rated for use in cast iron, stainless steel, carbon steel, and other ferrous and high-strength alloy materials, corresponding to workpiece material codes K, M, P, and S. Its 5xD flute-to-diameter ratio supports deeper drilling with chip evacuation in mind. Coolant-through construction delivers cutting fluid directly to the cutting edge, making it well-suited for CNC machining centers and other setups where internal coolant delivery is available. The MDW-HGS series is built for metal-cutting applications where tool life and hole quality are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eTiAlCr and TiSi dual coating for high-heat performance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e135-degree drill point angle reduces entry force and minimizes bit walk\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design for internal cutting fluid delivery at the drill tip\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration supports chip flow in deep-hole applications\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with h8 diameter tolerance for consistent tool holding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and drill presses equipped with internal coolant delivery. Rated for primary workpiece materials including cast iron, stainless steel, and carbon and alloy steels (material codes K, M, P, S). Accepts standard straight-shank tool holders sized for a 0.5469-inch shank diameter within the MDW-HGS series range of 0.5000 to 0.6500 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by qualified machinists following the machine tool manufacturer lockout procedure before securing or removing the bit. Verify tool holder collet or chuck capacity matches the 0.5469-inch shank diameter before clamping. Enable internal coolant supply before initiating the cut to protect the coating and cutting edge. Do not use this bit in hand-held drill applications; it is intended for rigid machine tool setups only.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 17\/32 inch (0.5313 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\u003eOverall Length\u003c\/strong\u003e: 6.9291 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.2520 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5469 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.5197 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.1100 inches (2.79 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\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\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 (Codes K, M, P, S)\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: U103748\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51751502086450,"sku":"U103748","price":587.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8588d253ce8933d61fa0ce0beba845df.jpg?v=1788923644","url":"https:\/\/voomisupply.com\/products\/sumitomo-u103748-solid-carbide-drill-bit-17-32-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
