It carries a multilayer TiAlN coating that extends tool life when drilling abrasive and heat-generating materials. The overall length measures 118.00 mm with a 71.00 mm flute length, providing the reach required for standard jobber-depth holes. A straight cylindrical shank with a 12 mm shank diameter seats securely in standard drill chucks and toolholders. The right-hand, regular spiral flute geometry promotes consistent chip evacuation, while the tapered web configuration adds rigidity at the cutting tip. This drill is intended for use by machinists and tool-and-die professionals working in production or maintenance environments.\u003c\/p\u003e\u003cp\u003eThis drill is designed for cutting steel, stainless steel, cast iron, aluminum, and other non-ferrous materials, making it suitable for a wide range of metalworking applications. The coolant-through capability allows cutting fluid to be delivered directly to the cutting zone, supporting higher feed rates and extended tool life in CNC machining centers, drill presses, and manual mills. The 5xD flute-to-diameter ratio provides adequate chip clearance in moderate-depth drilling operations. Maximum drilling depth is rated at 56.00 mm.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with multilayer TiAlN coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e140-degree point angle for reduced thrust and improved center-starting accuracy\u003c\/li\u003e\n\u003cli\u003eCoolant-through design delivers fluid directly to the cutting edge\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute geometry for consistent chip removal\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with 12 mm diameter fits standard chucks and ER collets\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537K specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber drill compatible with standard straight-shank drill chucks, ER collet systems, and hydraulic toolholders accepting a 12 mm shank diameter, suitable for use in CNC machining centers and conventional drill presses.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the drill. Confirm chuck or collet runout is within acceptable tolerance before cutting, as excess runout accelerates edge wear on carbide tooling. When using the coolant-through feature, verify that the coolant supply pressure and flow rate are compatible with the machine spindle before operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11.50 mm (0.4528 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 118.00 mm (4.6457 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 71.00 mm (2.7953 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 56.00 mm (2.2047 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12 mm (0.2813 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 45 mm (1.7717 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.97 mm (0.0776 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 Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Multilayer TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum, Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.28 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: 4149308\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742161764658,"sku":"4149308","price":266.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6047723244c39e297ff48cf30f8b8e5b_23e3ce8d-7201-46d2-bfe4-a16716594c58.jpg?v=1788835682","url":"https:\/\/voomisupply.com\/products\/kennametal-4149308-solid-carbide-jobber-drill-11-50mm","provider":"Voomi Supply","version":"1.0","type":"link"}
