It measures 11\/32 inches (0.3438 inches decimal) in diameter with a 135-degree split-point angle that reduces walking and improves entry accuracy. The bit features dual TiAlCr and TiSi coatings, which increase surface hardness and thermal resistance during high-speed drilling. Overall length is 5 inches with a straight-cylindrical shank. Coolant-through capability is built in, making this bit suitable for use with through-spindle coolant systems. It is sized to an h8 diameter tolerance for consistent, repeatable fit in precision drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for metal cutting applications, with primary workpiece material compatibility in cast iron, stainless steel, and carbon steel. It falls within the MDW-HGS series, which targets high-performance drilling at a 5xD flute-to-diameter ratio. Typical installation scenarios include CNC machining centers, manual drill presses, and production drilling setups where tool life and hole quality in ferrous and difficult-to-machine materials are critical. It is suited for machinists, toolroom technicians, and maintenance professionals working in manufacturing, fabrication, and heavy industrial environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard metal drilling\u003c\/li\u003e\n  \u003cli\u003eDual TiAlCr and TiSi coating combination for high thermal resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e135-degree point angle reduces thrust force and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports through-spindle coolant delivery for chip evacuation and heat control\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration reduces cutting resistance as the bit progresses through material\u003c\/li\u003e\n  \u003cli\u003eh8 diameter tolerance provides consistent shank fit for precision toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for metal cutting in cast iron, stainless steel, and steel workpieces. Compatible with toolholders accepting a 0.3594-inch straight-cylindrical shank. Suitable for CNC and manual drilling equipment equipped with through-spindle coolant capability. Part of the SUMITOMO MDW-HGS series for materials coded K, M, P, and S per ISO workpiece material classification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician familiar with carbide tooling and proper tool-holding procedures. Power down and lock out the spindle before inserting or removing the bit. Solid carbide is brittle compared to high-speed steel — avoid side loading, interrupted cuts beyond the tool design parameters, or dropping the bit on hard surfaces. Confirm coolant lines are clear and delivering adequate flow before initiating through-spindle coolant drilling cycles.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/32 inches (0.3438 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\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\u003eOverall Length\u003c\/strong\u003e: 5.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.8346 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3594 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.1654 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eDrill Point Length\u003c\/strong\u003e: 0.0712 inches (1.81 mm)\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 Material\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Code\u003c\/strong\u003e: 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\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: U103722\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51732052377906,"sku":"U103722","price":280.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a33a34cdd9bcc830ef111facb7ee64e0.jpg?v=1788738685","url":"https:\/\/voomisupply.com\/products\/sumitomo-u103722-jobber-drill-bit-11-32-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
