Built to DIN 6537K specification, it features a 140-degree standard point angle and a multilayer TiAlN coating that extends tool life in abrasive and high-temperature cutting conditions. The bit measures 0.1360 inches (No. 29 wire gauge) in drill diameter, with a 1.5748-inch flute length and a 3-inch overall length. The KC7325 carbide grade and tapered web configuration make it well suited for high-productivity drilling in ferrous and non-ferrous materials where consistent hole geometry matters.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in machine-shop and production environments where wire-gauge-size holes are required in metal components. The straight cylindrical shank with a 0.2362-inch diameter seats directly in standard collet chucks or drill chucks. The 8xD flute-length-to-diameter ratio supports deeper hole entry, and the coolant-through design allows internal coolant delivery to the cutting zone, which helps manage chip evacuation and heat at the tip during extended drilling cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in KC7325 grade for rigidity and wear resistance in metal drilling\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating reduces thermal wear and extends tool life in dry and semi-dry cutting\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle provides clean entry and reduces thrust force\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery for chip evacuation and heat control\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds core strength without sacrificing chip flow\u003c\/li\u003e\n  \u003cli\u003eDIN 6537K specification ensures consistent dimensional standards for drop-in replacement use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement drill bit for CNC machining centers and drill presses using straight-shank collet or drill chuck toolholders accommodating a 0.2362-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool changer or chuck is in a safe state before seating or removing the bit. Verify shank engagement depth in the collet meets shop standards before torquing the chuck. When using coolant-through capability, confirm that the toolholder and spindle coolant passages are clean and properly connected before beginning 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 Size (Wire)\u003c\/strong\u003e: No. 29\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1360 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\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\u003eFlute Length\u003c\/strong\u003e: 1.5748 inches (40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches (78 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: 1.2992 inches (33 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0221 inches (0.56 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\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\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches (-0.012 to 0.000 mm)\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: 0.04 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: 4149598\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743223185714,"sku":"4149598","price":219.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7185c56699f919bb2817435195c817f.jpg?v=1788844119","url":"https:\/\/voomisupply.com\/products\/kennametal-4149598-taper-length-drill-bit-no-29","provider":"Voomi Supply","version":"1.0","type":"link"}
