Built to DIN 6537K standards, this bit features a 140-degree split point geometry with web thinning for reduced thrust force and improved chip evacuation at entry. The multilayer TiAlN coating provides heat resistance and extended tool life in abrasive materials. With a 0.5-inch cutting diameter and a compact 4.2126-inch overall length, it delivers rigidity and accuracy in short-reach drilling applications. Installed by machinists and tool-and-die technicians on CNC machining centers, drill presses, and automatic screw machines.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production drilling in cast iron and steel workpieces where tight hole tolerances and consistent performance are required. The screw machine length design keeps the bit close to the spindle, reducing deflection during high-feed-rate operations. The straight cylindrical shank at 0.5512 inches in diameter seats securely in standard drill chucks and collet holders. Typical applications include through-hole drilling, stepped-hole preparation, and multi-part fixture runs in metalworking production settings.\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 for thermal resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle with web-thinned geometry reduces entry thrust\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification ensures dimensional consistency and interchangeability\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral flute for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCompact screw machine length minimizes deflection in short-reach drilling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for standard drill chucks and collet systems accepting a 0.5512-inch straight cylindrical shank; primary workpiece materials are cast iron and steel per manufacturer specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine powered down and the spindle fully stopped. Secure the straight shank firmly in a properly sized drill chuck or collet to the chuck manufacturer's recommended torque specification. Verify spindle runout before production use, as carbide is brittle and sensitive to lateral loading. Consult applicable shop safety standards and machine manufacturer guidelines for speeds and feeds when drilling cast iron or steel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.2126 inches (107.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 60.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.6929 inches (43.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5512 inches (14.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.7717 inches (45.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 2.20 mm\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.007 to +0.025 mm\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\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B966\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3638 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: 1913504\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737052741938,"sku":"1913504","price":300.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0fa992c9d8d43b83ce6e79238d570374.jpg?v=1788783655","url":"https:\/\/voomisupply.com\/products\/kennametal-1913504-carbide-drill-bit-1-2-inch-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
