Built to DIN 6537K specification, this bit uses a 140-degree standard point and a multilayer TiAlN coating to extend tool life at elevated cutting temperatures. The No. 14 wire size corresponds to a 0.182-inch (0.1820 in) diameter. At 87 mm (3.43 inches) overall length with a 49 mm (1.93 inches) spiral flute, this bit is designed for machinists, toolroom technicians, and CNC operators who need consistent hole geometry and tight tolerances in production environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for ferrous and non-ferrous metal drilling where extended reach and close-tolerance hole quality are required. The straight cylindrical shank with a 6 mm (0.2362 inch) diameter allows direct chuck mounting in standard drill chucks or collet systems. Coolant-through capability supports high-speed machining in applications where internal coolant delivery is available, helping to clear chips and manage heat in deep-hole operations up to 41 mm (1.614 inches) maximum drilling depth.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction in material grade KC7325 for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating resists heat buildup and oxidation at high cutting speeds\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle reduces thrust force and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for deep-hole chip evacuation\u003c\/li\u003e\n\u003cli\u003e8xD flute-length-to-diameter ratio provides extended reach with a tapered web configuration\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with DIN 6537K specification ensures predictable, repeatable geometry\u003c\/li\u003e\n\u003cli\u003eTight diameter tolerance of -0.0005 to 0.0000 inches ensures close-fit hole quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for solid carbide taper length drill bits in the KENNAMETAL B053A-CPG series, compatible with standard straight-shank drill chucks and collet toolholders accepting a 6 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified machinists or toolroom technicians following applicable shop safety procedures. Secure the straight shank firmly in a properly sized collet or drill chuck before operation to prevent runout. Ensure the machine spindle is fully stopped before inserting or removing the bit. When using coolant-through capability, verify that coolant pressure and flow rate are compatible with the machine spindle and toolholder before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B053A-CPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1820 inches\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\/Finish\u003c\/strong\u003e: Multilayer TiAlN\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\u003eCoolant Through\u003c\/strong\u003e: Yes\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 inches)\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\u003eFlute Length\u003c\/strong\u003e: 49 mm (1.9291 inches)\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: 87 mm (3.43 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 41 mm (1.6142 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.77 mm (0.0301 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches (-0.012 to 0.000 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Number\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 4149619\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":67647495995698,"sku":"4149619","price":259.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5cd08b2d5d544bfb28965121c0413198_349f1bf8-01d3-49c4-8874-e4e116bc00bf.jpg?v=1790459775","url":"https:\/\/voomisupply.com\/products\/kennametal-4149619-taper-length-drill-bit-no-14","provider":"Voomi Supply","version":"1.0","type":"link"}
