Manufactured from C2-grade solid carbide with a bright\/uncoated finish, this bit measures 1\/8 inch (0.1250 inch decimal) in diameter and features a 140-degree notched point geometry. The web-thinned design reduces thrust requirements at entry and improves chip clearance. With two right-hand cutting flutes and tight diameter tolerances of +0.0000 to -0.0005 inches, this bit is suited for applications where hole accuracy and tool life in hard alloys are the primary concerns. It weighs 0.02 pounds.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for professional machinists and tool-room applications where the workpiece material demands carbide hardness and edge retention. Primary and secondary workpiece materials include chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy. It is well-suited for CNC drilling operations, fixture work, and precision hole-making in aerospace, defense, and industrial manufacturing environments where consistent hole quality in tough substrates is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eC2-grade solid carbide construction for hardness and wear resistance in tough alloys\u003c\/li\u003e\n  \u003cli\u003e140-degree notched point geometry reduces walking and improves entry accuracy\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned design lowers thrust force requirements and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eTight diameter tolerance of +0.0000 to -0.0005 inches for close-tolerance hole work\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish compatible with a wide range of cutting fluids and coolant strategies\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with two flutes for standard CNC and manual drill press use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/8-inch drill chucks and collet systems. Rated for drilling chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy workpieces. No coolant-through capability; external coolant application recommended for extended cuts in hard materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with carbide tooling requirements. Secure the bit firmly in a collet or drill chuck rated for the shank diameter before operation. Carbide is brittle and susceptible to fracture under side-loading or interrupted cuts; avoid flexing the bit during use. Always verify spindle speed and feed rate settings are appropriate for the workpiece material and bit diameter before starting the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 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: Solid 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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: 74129156\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743961219378,"sku":"74129156","price":29.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1af4fdd618ff1069287134dcf99ba696.jpg?v=1788852000","url":"https:\/\/voomisupply.com\/products\/hertel-74129156-straight-flute-drill-bit-1-8-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
