Built to DIN 6537K specification and offered in material grade KC7325, this bit features a 140-degree standard point angle and a multilayer TiAlN coating that resists heat and wear at elevated cutting speeds. The wire gauge size is No. 12, corresponding to a decimal diameter of 0.1890 inches. The straight cylindrical shank measures 0.2362 inches in diameter, and the overall length is 3.75 inches. Coolant-through capability supports chip evacuation and tool life in deep-hole operations. Licensed machinists and CNC operators working in production environments are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for high-speed drilling in ferrous and non-ferrous metals, hardened alloys, and other materials where carbide tooling is required over high-speed steel alternatives. The 8xD flute-to-diameter ratio and maximum drilling depth of 1.8898 inches make it appropriate for taper length reach requirements in tight-tolerance machining centers, VMCs, and drill presses equipped for straight-shank tooling. It is a single-piece tool sold individually with a minimum order quantity of one.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in material grade KC7325 for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating extends tool life at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle reduces thrust and improves centering accuracy\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with tapered web configuration per DIN 6537K\u003c\/li\u003e\n  \u003cli\u003e8xD flute length ratio provides reach beyond standard jobber length bits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a taper length straight-shank carbide drill bit compatible with CNC machining centers, VMCs, and drill presses that accept straight cylindrical shanks with a 0.2362-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle and toolholder are fully de-energized and at rest before inserting or removing the bit. Confirm that the straight cylindrical shank is properly seated and clamped to the required runout tolerance before beginning a cutting cycle. Coolant supply lines should be verified and connected before use when operating with through-spindle coolant.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B053A-CPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Number\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: KC7325\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\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\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1890 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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\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 Length\u003c\/strong\u003e: 2.2047 inches (56 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length x Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches (94 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 inches (6 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (36 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.8898 inches (48 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0313 inches (0.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 4149622\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740469526834,"sku":"4149622","price":269.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5cd08b2d5d544bfb28965121c0413198_f0fe10bf-07ba-41fb-aa3c-b455de8a6471.jpg?v=1788825210","url":"https:\/\/voomisupply.com\/products\/kennametal-4149622-taper-length-drill-bit-no-12","provider":"Voomi Supply","version":"1.0","type":"link"}
