It features a 11.80 mm (0.4646 inch) cutting diameter, a 140-degree point angle for self-centering entry and reduced thrust, and a multilayer TiAlN coating that extends tool life under elevated cutting temperatures. The overall length is 118.00 mm (4.6457 inches) with a 71.00 mm (2.7953 inch) flute length, and it includes a coolant-through design that delivers cutting fluid directly to the cutting zone. Licensed machinists and CNC operators working in job shops, aerospace, and general manufacturing will find this drill suited to high-speed, high-feed applications.\u003c\/p\u003e\u003cp\u003eThis drill is designed for use on steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. It conforms to DIN 6537K geometry and fits the 10.00 mm to 12.50 mm drill diameter range. The straight cylindrical shank with a 12 mm shank diameter and 45 mm shank length mounts directly in standard drill chucks, collet chucks, and shrink-fit toolholders. A maximum drilling depth of 56.00 mm (2.2047 inches) makes it effective in through-hole and blind-hole operations across a wide range of workpiece materials encountered in production machining.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance superior to high-speed steel in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating improves heat resistance and extends tool life in steel and stainless steel applications\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces thrust force and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design delivers cutting fluid directly to the cutting edge, supporting higher feed rates and improved chip evacuation\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry with a 5xD flute-to-diameter ratio provides good chip flow in a jobber-length package\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification ensures dimensional consistency and compatibility with standard tooling systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification solid carbide jobber drill conforming to DIN 6537K, compatible with standard straight-shank drill chucks, collet chucks, and shrink-fit toolholders accepting a 12 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation of this drill should be performed by qualified machinists or CNC operators familiar with carbide tooling. Ensure the machine spindle and toolholder are clean and true before seating the shank, as runout will accelerate carbide chipping. Verify that the coolant-through supply is active and at adequate pressure before engaging the cut. Handle carbide tooling carefully to avoid edge chipping from impact with hard surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11.80 mm (0.4646 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\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\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: 2.03 mm (0.0799 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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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: Steel, Stainless Steel, Cast Iron, Aluminum and 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\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 4149312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743101911346,"sku":"4149312","price":266.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6047723244c39e297ff48cf30f8b8e5b_552e3ce2-e6df-4313-aebc-bcf424b11c52.jpg?v=1788842694","url":"https:\/\/voomisupply.com\/products\/kennametal-4149312-solid-carbide-jobber-drill-11-80mm","provider":"Voomi Supply","version":"1.0","type":"link"}
