At 17\/64 inch (0.2656 inches) in diameter, this bit features a 135-degree split point angle that reduces walking and minimizes the need for a center punch on flat surfaces. The MDW-GS series construction uses a tapered web configuration with a straight-cylindrical shank, keeping the tool rigid and accurate in short-reach drilling applications. With an overall length of 2.874 inches and a flute length of 1.299 inches, this bit is suited for CNC machining centers, drill presses, and production environments where repeatable hole quality is required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in production machining applications targeting cast iron and steel workpieces. The screw machine length format provides added rigidity compared to jobber-length bits, making it well suited for tight-tolerance work in automated or semi-automated setups. The 2-flute geometry and coated carbide construction support efficient chip evacuation and extended tool life in high-cycle operations. Maximum drilling depth is 0.9006 inches (22.88 mm), and the 2xD flute-by-diameter ratio is optimized for shallow-to-moderate depth holes in hard materials.\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\u003e135-degree drill point angle reduces entry walking and thrust force\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration improves core strength and chip flow\u003c\/li\u003e\n  \u003cli\u003eScrew machine length format provides superior rigidity over jobber-length alternatives\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance h8 ensures consistent fit and repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a screw machine length replacement drill bit for production machining applications involving cast iron and steel workpieces, compatible with standard drill chucks and collets accepting a straight-cylindrical shank in the 0.2500 to 0.3000 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully powered down and locked out per facility lockout\/tagout procedures. Ensure the chuck or collet is clean and free of debris before seating the shank to maintain concentricity. Solid carbide tooling is brittle and should not be subjected to side loads or interrupted cuts beyond the tool design parameters. Inspect the cutting edges for chipping before each use and replace if edge integrity is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 17\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.2656 inches\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 Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.874 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.299 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.575 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.055 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.9006 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: 2xD\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: Coated\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MDW-GS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: U101080\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51730135122226,"sku":"U101080","price":132.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e74a2e0ecf53a9dcd0775321ad0db189.jpg?v=1788712334","url":"https:\/\/voomisupply.com\/products\/sumitomo-u101080-screw-machine-drill-bit-17-64-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
