It measures 13\/64 inch (0.2031 inches) in diameter and features a 135-degree drill point angle, which reduces walking on entry and suits flat or curved workpiece surfaces. The bit carries a dual TiAlCr and TiSi coating that improves heat resistance and extends tool life at elevated cutting speeds. Overall length is 3.937 inches with a straight-cylindrical shank diameter of 0.2344 inches. This bit belongs to the MDW-HGS series and is installed by machinists and CNC operators working in high-production metal cutting environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for cutting cast iron, stainless steel, and steel, corresponding to ISO workpiece material codes K, M, P, and S. The 5xD flute-to-diameter ratio and tapered web configuration support chip evacuation in deeper holes. Coolant-through design allows internal coolant delivery directly to the cutting edge, making it well suited for machining centers and CNC lathes equipped with through-spindle coolant systems. It is appropriate for both general-purpose shop use and high-volume production runs where consistent hole tolerance and tool life matter.\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 applications\u003c\/li\u003e\n  \u003cli\u003eTiAlCr and TiSi dual coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e135-degree split point angle reduces entry walking and thrust force\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery to the cutting zone\u003c\/li\u003e\n  \u003cli\u003eTapered web and 5xD flute ratio promote efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on cast iron, stainless steel, and steel workpieces (ISO material codes K, M, P, S) in machining centers, CNC mills, and drill presses equipped with through-spindle or external coolant.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before loading or changing the bit. Seat the shank fully and evenly in the collet or drill chuck and verify runout before commencing a cut. Confirm coolant flow path is clear before engaging through-spindle coolant if applicable.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 13\/64 inch (0.2031 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: 3.937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.7323 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2344 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.126 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0421 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\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\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 Material\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MDW-HGS\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: 0.05 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: U103689\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51733717385522,"sku":"U103689","price":170.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5c10f019ef4213a1bb928049776d9337.jpg?v=1788758773","url":"https:\/\/voomisupply.com\/products\/sumitomo-u103689-jobber-drill-bit-13-64-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
