Ground to a 140-degree split point, it delivers self-centering entry and reduced thrust compared to standard 118-degree geometry. The multilayer TiAlN coating provides thermal resistance and extended edge life in abrasive and hard materials. With an overall length of 4.0551 inches and a flute length of 2.4016 inches, this 21\/64-inch diameter drill follows DIN 6537K standards and is suited for use in CNC machining centers and production drilling environments. Installation and operation are typically handled by machinists and tooling technicians.\u003c\/p\u003e\u003cp\u003eThis drill is intended for cutting steel, stainless steel, cast iron, aluminum, and non-ferrous metals. The 5xD flute-to-diameter ratio and regular spiral flute design promote efficient chip evacuation in these materials. It is a right-hand cutting tool with a straight cylindrical shank measuring 0.6250 inches in diameter, making it compatible with standard drill chucks and collet systems used in vertical machining centers, drill presses, and CNC lathes. It does not feature coolant-through capability, so external coolant or cutting fluid application is recommended when drilling ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with standard point type for self-centering entry and reduced walking\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating for thermal resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry promotes consistent chip flow and evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 0.6250 inches diameter fits standard chucks and collet holders\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 for use in steel, stainless steel, cast iron, aluminum, and non-ferrous materials per the manufacturer specification. Compatible with standard drill chucks and collet toolholders accepting a 0.6250-inch straight shank.

Ensure the machine spindle is fully stopped and de-energized before changing tooling. Confirm the shank is fully seated and secured in the chuck or collet holder to the holder manufacturer's recommended clamping procedure before operation. Because this drill does not have coolant-through capability, apply external cutting fluid or coolant at the cutting zone when working ferrous materials to manage heat buildup and extend tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 21\/64 inch (0.3281 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint 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: 4.0551 inches (103.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.4016 inches (61.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6250 inches (10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5748 inches (40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.9291 inches (49.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0557 inches (1.41 mm)\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\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\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0006 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum, Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 4150715\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739406369074,"sku":"4150715","price":159.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/027550a92e9fb7c9c67a753ee7e2e1a8_c44e770f-8709-4506-9b5e-9e4c84e76b68.jpg?v=1788814211","url":"https:\/\/voomisupply.com\/products\/kennametal-4150715-solid-carbide-jobber-drill-21-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
