Built from solid carbide with a multilayer TiAlN coating, it delivers high wear resistance and thermal stability at elevated cutting speeds. The 140-degree standard point geometry reduces thrust force and improves centering accuracy. At 13\/32 inch (0.4062 inch) diameter with a flute length of 3.70 inches and an overall length of 5.55 inches, this drill suits through-coolant setups where chip evacuation and tool life are critical priorities. It is typically installed by machinists and tool-and-die professionals in CNC drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for high-speed CNC machining centers and drilling operations requiring tight tolerances and extended reach. The 8xD flute-to-diameter ratio supports deeper drilling passes while maintaining rigidity. The straight cylindrical shank provides secure chuck or collet retention. Through-coolant capability makes it well matched to operations in hardened steels, stainless alloys, cast iron, and similar difficult-to-machine materials where heat management and chip flushing are essential to hole quality and tool longevity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in material grade KC7325 for extended tool life in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating enhances heat resistance and reduces built-up edge at high surface speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle for reduced thrust and improved self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capable design supports chip flushing and thermal control during deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003e8xD flute length-to-diameter ratio allows drilling depths up to 3.11 inches (79 mm) in a single pass\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with tapered web configuration per DIN 6537K specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option within the KENNAMETAL B053A-CPG series for CNC machining centers and drilling fixtures accepting a straight cylindrical shank with a 0.4724 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Secure the straight shank in a compatible collet or drill chuck rated for the shank diameter before engaging coolant supply lines if through-coolant operation is intended. Verify spindle speed and feed rate parameters against the workpiece material and machine capability before commencing drilling. Always power down and lock out the machine spindle before changing or inspecting the drill bit.\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\u003eDrill Bit Diameter\u003c\/strong\u003e: 13\/32 inch (0.4062 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: KC7325\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Multilayer TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.70 inches (94 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.55 inches (141 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: 0.4724 inch (12 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.77 inches (45 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.11 inches (79 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 8xD\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Number\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.67 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: 4149737\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740197028146,"sku":"4149737","price":493.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5cd08b2d5d544bfb28965121c0413198_173e95f9-9761-4cad-8777-003408401e84.jpg?v=1788823442","url":"https:\/\/voomisupply.com\/products\/kennametal-4149737-taper-length-drill-bit-13-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
