Built from solid carbide and coated with a multilayer TiAlN finish, this bit delivers extended tool life and thermal resistance when drilling cast iron and steel. The 140-degree point angle reduces thrust and improves entry accuracy, while the web-thinned, parallel-web geometry minimizes cutting resistance at the chisel edge. At 4.8425 inches overall length with a 2.874-inch flute length, this stub-length format provides rigidity over longer drill bits, making it a reliable choice for high-cycle production drilling applications.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for use in CNC machining centers, drill presses, and production screw machines where tight tolerances and repeatability are required. The straight cylindrical shank at 0.7087 inches (18.00 mm) diameter seats securely in standard collets and chucks. Primary workpiece materials are cast iron and steel. With coolant-through capability, it is well suited for deep-hole work where chip evacuation and heat management are critical. Maximum drilling depth is 2.008 inches. It follows DIN 6537K specification and is classified under Series B976.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating provides thermal and oxidation resistance at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces entry thrust and improves hole location accuracy\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web reduces cutting force at the chisel edge\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip flushing and heat control in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard collet and drill chuck systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length replacement drill bit for production drilling applications in cast iron and steel, conforming to DIN 6537K specification under Series B976.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify the shank diameter matches the collet or chuck bore to prevent runout. Do not exceed the recommended maximum drilling depth of 2.008 inches without retracting to clear chips, especially in blind-hole applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/16 inch (0.6875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.8425 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.874 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.008 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.7087 inches (18.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.8898 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.119 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (Multilayer)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Parallel, Web-Thinned\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, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.007 to +0.025 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B976\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6834 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2649384\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51729671389490,"sku":"2649384","price":793.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8439eb5b514677448e3da9b5e16550d5_ca0346a0-8f2e-424b-bfec-013d1d89c01a.jpg?v=1788707543","url":"https:\/\/voomisupply.com\/products\/kennametal-2649384-drill-bit-11-16-inch-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
