Built from solid carbide with a multi-layer DEX coating, this bit delivers superior wear resistance and heat management in production environments. The 135-degree web-thinned point reduces thrust force and promotes accurate self-centering on entry. At 2.6772 inches overall length with a 0.6890-inch flute length, it is sized for stub-length rigidity in drill press, CNC machining center, and automated screw machine setups. Coolant-through capability supports chip evacuation and tool life in deep-hole applications. Installed by machinists and tool-and-die professionals in shop and production environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered for drilling steel, stainless steel, cast iron, and high-temperature alloys. The 3xD flute-to-diameter ratio and regular spiral flute geometry are suited for through-hole and blind-hole operations where dimensional accuracy and surface finish matter. The straight cylindrical shank with a 0.1250-inch shank diameter fits standard drill chucks and collet systems. It is commonly used in CNC machining cells, manual drill presses, and screw machine setups processing ferrous and heat-resistant workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for hardness and thermal stability in ferrous and high-temp alloy drilling\u003c\/li\u003e\n\u003cli\u003eMulti-layer DEX proprietary coating reduces friction and extends tool life\u003c\/li\u003e\n\u003cli\u003e135-degree web-thinned point geometry for reduced entry thrust and self-centering accuracy\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip flushing and heat removal in deep-hole operations\u003c\/li\u003e\n\u003cli\u003eTapered web configuration with 2 regular spiral flutes for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eh8 diameter tolerance ensures close-fit hole quality in precision machining applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the SUMITOMO MDW-HGS series.

Secure the straight cylindrical shank fully within the chuck or collet to the recommended grip depth before operation. Coolant-through setups require compatible toolholders with internal coolant supply passages. Follow applicable shop safety procedures and machine tool manufacturer guidelines when setting spindle speed and feed rate for carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7\/64 inches (0.1094 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.6772 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.6890 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.9291 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.5248 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: 0.0227 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eNumber of Margins\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Multi-layer DEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temp Alloy\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: 0.025 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: U101011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51743371034930,"sku":"U101011","price":145.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c0ca56efb48e8007efd689f0ff98839b_25bf998a-64db-498b-aafe-ce034c5eb939.jpg?v=1788846304","url":"https:\/\/voomisupply.com\/products\/sumitomo-u101011-screw-machine-drill-bit-7-64-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
