The 12.50 mm cutting diameter pairs with a 140-degree split point for aggressive penetration and reduced thrust in hard materials. A multilayer TiAlN coating extends tool life by resisting heat and wear at elevated cutting speeds. Overall length is 124.00 mm with a 77.00 mm flute length and a straight cylindrical shank measuring 14 mm in diameter. The right-hand spiral flute geometry promotes efficient chip evacuation. This drill is intended for use by machinists, tool-and-die makers, and maintenance professionals working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 4150770 is engineered for drilling steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. Its 5xD flute-to-diameter ratio makes it well suited for moderate-depth holes in both manual and CNC setups. The DIN 6537K specification ensures dimensional consistency for shops that standardize to metric tooling. The tapered web configuration adds rigidity at the drill tip, which helps maintain positional accuracy and reduces walking on entry. No through-coolant is required, making this drill compatible with standard drill presses, machining centers, and CNC lathes without coolant-through capability.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life versus high-speed steel alternatives\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating resists heat and abrasive wear in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eRegular right-hand spiral flute promotes consistent chip evacuation in through and blind holes\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet holders without adapters\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537K specification for metric dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber drill for use in standard drill chucks and collet systems accepting a 14 mm straight shank, compatible with CNC machining centers, drill presses, and lathes configured for right-hand rotation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the spindle fully stopped and the machine in a locked-out, de-energized state per applicable machine safety procedures. Secure the straight shank firmly in a drill chuck or ER collet holder rated for the shank diameter before operation. Inspect the cutting edges and coating for chips or damage before each use, as carbide is brittle and should not be reinstalled if the edge is compromised. Feeds and speeds should be set according to the workpiece material and machine rigidity; consult the tooling manufacturer cutting data for steel and stainless steel grades.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 12.50 mm (0.4921 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\u003eOverall Length\u003c\/strong\u003e: 124.00 mm (4.8819 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 77.00 mm (3.0315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 14 mm (0.4063 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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 60.00 mm (2.3622 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 2.15 mm (0.0846 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\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\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum and Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\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: -0.0007 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.41 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 14.5 x 1.4 x 1.4 inches\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: 4150770\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51741229908274,"sku":"4150770","price":311.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/027550a92e9fb7c9c67a753ee7e2e1a8_0227d59c-dc49-4116-8b7e-ac87cff6410f.jpg?v=1788830199","url":"https:\/\/voomisupply.com\/products\/kennametal-4150770-solid-carbide-jobber-drill-12-50mm","provider":"Voomi Supply","version":"1.0","type":"link"}
