Built from C2-grade carbide with a bright, uncoated finish, this bit measures 9\/64 inches (0.1406 inches decimal) in diameter and features a 140-degree notched point for fast, accurate penetration. The two-flute, right-hand cutting geometry combined with web thinning reduces thrust and improves chip evacuation. It is suited for production and maintenance drilling applications where standard high-speed steel bits fail to hold an edge. A diameter tolerance of +0.0000 to -0.0005 inches ensures consistent hole sizing across runs.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for drilling chrome alloy, heat-treated alloy, nickel alloy, stainless steel, carbon steel, and titanium alloy workpieces. It fits production machine shop environments, aerospace component fabrication, industrial maintenance, and precision metalworking applications where hole quality and tool life in tough materials are the primary concerns. The straight-flute design is particularly effective in materials prone to work hardening, where a standard spiral flute may chatter or deflect.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eC2-grade carbide construction for extended tool life in hard alloys and stainless steel\u003c\/li\u003e\n\u003cli\u003e140-degree notched point reduces walking and lowers entry thrust\u003c\/li\u003e\n\u003cli\u003eWeb-thinned geometry improves chip clearance and lowers feed force requirements\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish maintains close dimensional tolerance without coating buildup\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, two-flute straight configuration for stable performance in work-hardening materials\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches for consistent hole accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or production-run drill bit for standard drill chucks and CNC toolholders accepting a 9\/64-inch straight shank; compatible with primary and secondary workpiece materials including chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy as specified by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by machinists or qualified metalworking technicians familiar with carbide tooling. Secure the shank fully in the chuck or collet before operation and verify runout before beginning a production run. Carbide is brittle  -  avoid side loading, impact, or interrupted cuts without confirming the bit is rated for that application. Power down and de-energize the machine spindle completely before changing or inspecting tooling.\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 (Inch)\u003c\/strong\u003e: 9\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal)\u003c\/strong\u003e: 0.1406 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Inch)\u003c\/strong\u003e: 9\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal)\u003c\/strong\u003e: 0.1406 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\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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\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: 0.02 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: 74129164\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51741931340082,"sku":"74129164","price":33.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c4ab6723f2a5beacd2caffed092fbd8.jpg?v=1788834401","url":"https:\/\/voomisupply.com\/products\/hertel-74129164-carbide-straight-flute-drill-bit-9-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
