Built from cobalt steel with a titanium nitride (TiN) coating, this bit delivers extended tool life and heat resistance in demanding production environments. It carries a wire gauge size 49 designation, equating to 0.0730 inches in decimal, and features a 135-degree split point that reduces walking and requires no center punch on most surfaces. The overall length is 1-11\/16 inches, making it well suited for short-reach, high-cycle drilling in turret lathes, screw machines, and CNC setups. Right-hand cutting with a regular spiral flute pattern ensures efficient chip evacuation.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in production machining environments where close-tolerance small-diameter holes are required. Typical applications include screw machine operations, turret lathe work, and CNC drilling of ferrous metals, stainless steel, and other hard alloys where cobalt tooling is the standard choice over high-speed steel. The short flute length of 11\/16 inches and straight-cylindrical shank make it easy to chuck in standard drill chucks or collet holders without modification. It is appropriate for both job shop and high-volume production settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt steel construction for superior heat and wear resistance compared to standard HSS bits\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends tool life and reduces friction during cutting\u003c\/li\u003e\n  \u003cli\u003e135-degree split point minimizes drill walk and reduces feed pressure\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel web configuration improves chip flow and reduces thrust load\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders without adapters\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty grade rated for demanding production drilling cycles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard production tool for screw machine and short-drill applications requiring a wire gauge size 49 (0.0730 inches) diameter straight-shank drill bit with a 135-degree split point.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians setting up screw machines, turret lathes, or CNC drilling equipment. Ensure the machine is powered down and all motion has stopped before changing tooling. Secure the straight-cylindrical shank fully within the chuck or collet to the recommended gripping depth and verify runout before beginning a production run. Cobalt bits should be run at appropriate cutting speeds for the workpiece material to avoid overheating the cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 49\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0730 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11\/16 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: 0.0730 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66692252\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":67951963111730,"sku":"66692252","price":38.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b78ea447a13f7ef860ecb50b60e6fb0.jpg?v=1791742478","url":"https:\/\/voomisupply.com\/products\/hertel-66692252-drill-bit-size-49-cobalt-tin-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
