Built from solid carbide and coated with TiAlCr and TiSi, it delivers extended tool life and thermal resistance at elevated cutting speeds. The bit measures 0.213 inches in diameter (wire size 3) with a 135-degree drill point angle that reduces thrust and improves self-centering on entry. The overall length is 3.937 inches with a straight-cylindrical shank. With a 5xD flute-to-diameter ratio and coolant-through capability, this bit is suited for use in CNC machining centers and other high-feed drilling operations. Machinists and toolroom technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for cutting cast iron, stainless steel, and carbon and alloy steels, corresponding to material codes K, M, P, and S in the ISO workpiece classification system. It is well suited to production drilling applications where tool life, hole quality, and dimensional consistency are priorities. The tapered web configuration reduces cutting resistance and supports chip evacuation in deep-hole drilling cycles. Its h8 diameter tolerance ensures reliable fit in standard drill chucks and precision collet systems.\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 and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiAlCr and TiSi dual coating provides thermal stability and oxidation resistance at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces axial thrust and improves entry accuracy without center-punching\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery for deep-hole applications\u003c\/li\u003e\n  \u003cli\u003e5xD flute-by-diameter ratio balances chip clearance and core strength\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with h8 diameter tolerance for precise chuck and collet seating\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration promotes efficient chip evacuation and reduces recutting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production-use drill bit in the SUMITOMO MDW-HGS series, suitable for CNC machining centers and drill presses equipped with standard straight-shank toolholders accepting 0.2344-inch shank diameters.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by qualified machinists with the machine powered down and in a locked-out, tagged-out state per applicable safety procedures. Seat the straight-cylindrical shank fully in the collet or drill chuck and verify concentricity before cutting. When using coolant-through capability, confirm the toolholder and spindle support internal coolant delivery before activating the coolant circuit. Do not exceed the manufacturer-rated feed and speed parameters for the workpiece material being drilled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.2130 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\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 Bit Finish\/Coating\u003c\/strong\u003e: TiAlCr and TiSi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.7323 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: 0.0441 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\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\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: U103691\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51730578145586,"sku":"U103691","price":170.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b1a12852dc22de4334cd819ffe3b075.jpg?v=1788719827","url":"https:\/\/voomisupply.com\/products\/sumitomo-u103691-solid-carbide-jobber-drill-bit-wire-3","provider":"Voomi Supply","version":"1.0","type":"link"}
