Built from solid carbide and coated with a multilayer TiAlN finish, this bit handles high-heat, high-speed drilling in ferrous and non-ferrous materials. The 140-degree standard point reduces thrust and self-centers quickly on entry. With a 13\/64 inch (0.2031 inch decimal) diameter and a straight cylindrical shank, it fits standard drill chucks and collet holders. Flute length runs 56 mm (2.2047 inches) and overall length is 94 mm (3.75 inches). Coolant-through capability supports high-performance applications where chip evacuation and thermal control are critical.\u003c\/p\u003e\n\u003cp\u003eThis drill bit suits CNC machining centers and manual drilling operations where tight tolerances and consistent hole quality are required. The right-hand spiral flute and tapered web configuration make it effective in production environments machining steel, stainless, cast iron, and similar alloys. The 8xD flute-to-diameter ratio provides extended reach for deeper holes relative to the bit diameter. Maximum drilling depth is 48 mm (1.8898 inches). Machinists, tool-and-die shops, and precision fabricators working to DIN 6537K standards will find this bit dimensionally consistent and ready for direct replacement or new-application use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in material grade KC7325 for wear resistance and cutting stability\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point reduces entry thrust and improves self-centering\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 for efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to -0.0005 to 0.0000 inches for consistent fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-application drill bit conforming to DIN 6537K specification, suitable for use in standard straight-shank drill chucks and collet systems accepting a 0.2362-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and tooling technicians on CNC or manual drilling equipment. Ensure the machine spindle is fully stopped and locked out before installing or removing the bit. Verify collet or chuck bore matches the 0.2362-inch shank diameter to prevent runout. When using the coolant-through feature, confirm coolant supply lines are connected and system pressure is appropriate for the machine before starting the cut.\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\/64 inch (0.2031 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: 56 mm (2.2047 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 94 mm (3.75 inches)\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: 6 mm (0.2362 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (1.4173 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 48 mm (1.8898 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-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\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Number\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 4149628\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740636512562,"sku":"4149628","price":227.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5cd08b2d5d544bfb28965121c0413198_2d02c5e0-1f83-41c2-888a-8c2111a8bc6d.jpg?v=1788826375","url":"https:\/\/voomisupply.com\/products\/kennametal-4149628-taper-length-drill-bit-13-64-inch-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
