Built from C2-grade carbide with a bright, uncoated finish, this bit features a 140-degree notched point and web-thinned geometry that reduces entry thrust and improves chip clearance at the cutting edge. The 7\/64-inch diameter measures 0.1094 inches in decimal, with a tight diameter tolerance of +0.0000 to -0.0005 inches for consistent hole sizing. Two right-hand flutes and a matching 7\/64-inch shank make this bit suitable for use in standard drill chucks and precision machine setups. Machinists, toolroom technicians, and industrial maintenance professionals are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for use in chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy workpieces. It is well suited to production drilling, toolroom work, and maintenance applications where consistent hole geometry in tough materials is required. The straight-flute design makes it particularly effective in short-chipping materials where spiral flutes may pack with chips. It is sold individually as a single-piece unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid C2-grade carbide construction for hardness and wear resistance in ferrous and exotic alloys\u003c\/li\u003e\n  \u003cli\u003e140-degree notched point for reduced thrust and self-centering entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned geometry reduces cutting force and improves chip ejection\u003c\/li\u003e\n  \u003cli\u003eTight diameter tolerance of +0.0000 to -0.0005 inches ensures consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003eStraight-flute design performs well in short-chipping materials including stainless steel and titanium alloy\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish for general-purpose use without coating-related dimensional buildup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy workpieces.

Secure the workpiece firmly before drilling and set spindle speed according to the workpiece material and manufacturer guidelines for carbide tooling. Coolant-through is not supported on this bit, so external coolant or cutting fluid is recommended when drilling hard alloys to manage heat buildup. Inspect the cutting edge before each use, as carbide is brittle and susceptible to chipping if dropped or subjected to side loading.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 7\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal)\u003c\/strong\u003e: 0.1094 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide, Grade C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (Fractional)\u003c\/strong\u003e: 7\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal)\u003c\/strong\u003e: 0.1094 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74129149\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51742803722546,"sku":"74129149","price":28.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d40099daa493009ad539dce5d3e67fe5.jpg?v=1788839499","url":"https:\/\/voomisupply.com\/products\/hertel-74129149-straight-flute-drill-bit-7-64-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
