It features a 135-degree split-point geometry that reduces thrust and walking on entry, paired with a multilayer TiAlN coating that extends tool life under high-heat cutting conditions. The straight cylindrical shank measures 0.5512 inches in diameter and fits standard drill chucks and collet holders. At 4.8819 inches overall length with a flute length of 3.0315 inches, it delivers a 5xD depth-to-diameter ratio suited to through-hole and moderate-depth drilling applications. Coolant-through capability supports chip evacuation and thermal management in production environments. This bit is intended for installation and use by machinists, tool-and-die professionals, and metalworking tradespeople.\u003c\/p\u003e\u003cp\u003eThe 4112512 is built for ferrous metal drilling, with steel listed as the primary workpiece material. It conforms to DIN 6537K specification, making it a recognized standard in CNC machining centers, drill presses, and manual metalworking setups. The 2-flute regular spiral configuration promotes efficient chip removal in straight and through-bore applications. A maximum drilling depth of 2.3622 inches (60 millimeters) and a tapered web configuration help maintain core strength throughout the cut. This drill is appropriate for both production-run use and precision one-off applications where consistent diameter tolerance is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in steel cutting\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating reduces heat buildup and extends tool life\u003c\/li\u003e\n\u003cli\u003e135-degree point angle minimizes drill walk and reduces entry thrust\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip evacuation and thermal management\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537K specification for dimensional consistency\u003c\/li\u003e\n\u003cli\u003eTapered web and 2-flute regular spiral for efficient chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification replacement or production drill for steel and ferrous metalworking applications requiring a 1\/2-inch diameter, DIN 6537K-compliant, straight-shank solid carbide jobber drill with coolant-through capability.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or metalworking professionals familiar with carbide tooling. Power down and de-energize the machine spindle completely before seating or removing the drill. Carbide tooling is brittle — avoid lateral loading, interrupted cuts beyond the tool's rated capacity, or dropping the bit on hard surfaces. Verify spindle runout and collet or chuck condition before use, as excessive runout accelerates edge chipping and reduces diameter accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: KCPK15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Multilayer TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.8819 inches (124 millimeters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.0315 inches (77 millimeters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5512 inches (14 millimeters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.3622 inches (60 millimeters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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: 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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: 0.007 to 0.025 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: 4112512\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750571934002,"sku":"4112512","price":861.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/705b77b4cb43652f3437c838ef1b4c53_8e67eb70-8049-49dd-9ebf-be8843af5f68.jpg?v=1788916853","url":"https:\/\/voomisupply.com\/products\/kennametal-4112512-solid-carbide-jobber-drill-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
