Built from C2 carbide with a bright, uncoated finish, it delivers hardness and edge retention when drilling through tough ferrous and non-ferrous metals. The bit measures 19\/64 inches (0.2969 inches decimal) in diameter with a 140-degree notched point and web-thinned tip geometry that reduces thrust and improves chip clearance on entry. Cutting direction is right hand, and the two-flute design maintains rigidity in straight-hole applications. This is a tool specified and used by machinists, tool-and-die technicians, and maintenance professionals working in precision metal fabrication environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for applications requiring tight diameter tolerances, with a diameter tolerance of +0.0000 to -0.0005 inches. It is designed to cut chrome alloy, heat-treated alloy, nickel alloy, stainless steel, carbon steel, and titanium alloy workpieces. The notched point and web-thinned geometry make it particularly effective in production and job-shop settings where hard, work-hardening materials are encountered regularly. The shank diameter matches the cutting diameter at 19\/64 inches (0.2969 inches decimal), allowing direct chuck mounting without a step-shank adapter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eC2 carbide tool material for hardness and wear resistance in ferrous and exotic metals\u003c\/li\u003e\n\u003cli\u003e140-degree notched point with web-thinned tip reduces entry thrust and improves centering\u003c\/li\u003e\n\u003cli\u003eTight diameter tolerance of +0.0000 to -0.0005 inches for precision hole sizing\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with or without cutting fluid\u003c\/li\u003e\n\u003cli\u003eTwo-flute straight design maintains bit rigidity in short, straight-hole drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction; compatible with standard drill presses, mills, and hand drills\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a straight-flute carbide drill bit for use in standard drill chucks and milling machine spindles accepting a 19\/64-inch round shank.

Carbide is brittle  -  avoid side-loading, interrupted cuts without appropriate feed rate reduction, or dropping the bit on hard surfaces. Use appropriate cutting fluid for the workpiece material to maximize tool life. Follow your shop's lockout\/tagout procedures when mounting or removing bits from powered equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Type\u003c\/strong\u003e: Straight-Flute\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Fractional)\u003c\/strong\u003e: 19\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal)\u003c\/strong\u003e: 0.2969 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 19\/64 inches (0.2969 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: Notched\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Chrome Alloy, Heat-Treated Alloy, Nickel Alloy, Stainless Steel, Steel, Titanium Alloy\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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74129263\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744030327090,"sku":"74129263","price":68.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9490e2268bcf6065ed54dc4c87ea0865.jpg?v=1788853213","url":"https:\/\/voomisupply.com\/products\/hertel-74129263-carbide-drill-bit-19-64-in-140-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
