It features a standard 118-degree split point with web thinning and a tapered web configuration for improved penetration and reduced thrust. The bright coating preserves the carbide substrate without adding dimensional buildup. At 2.2500 inches overall length with a 1.2500-inch spiral flute, this bit is suited for precision drilling in ferrous and non-ferrous metals, composites, and hard plastics. It is installed by machinists, tool-and-die technicians, and maintenance trades requiring tight-tolerance hole making.\u003c\/p\u003e\u003cp\u003eThis bit is designed for use in CNC machining centers, drill presses, and hand-held power tools with a straight-cylindrical chuck. The 0.1200-inch shank diameter matches the 0.1200-inch cutting diameter, making it compatible with standard collets and drill chucks sized for that range. It is a high-performance grade C2 carbide bit suited for production and job-shop environments where consistent hole geometry and drill life are required. Right-hand cutting direction is standard for conventional clockwise spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction, grade C2, for extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eNo. 31 wire size, 0.1200-inch cutting diameter with a tight tolerance of -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning and tapered web for reduced entry force\u003c\/li\u003e\n\u003cli\u003eBright finish — no coating thickness to affect hole diameter\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral design promotes chip evacuation in through-hole and blind-hole applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length drill bit for use in any drill press, CNC machining center, or hand-held power tool accepting a straight-cylindrical shank in the 0.1200-inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance technicians. Secure the shank fully in the drill chuck or collet before operation and verify runout before drilling tight-tolerance holes. Power down and de-energize the machine spindle before changing bits. Solid carbide bits are brittle — avoid side-loading or using in flex-shaft tools where lateral deflection can cause breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Grade C2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.2500 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: 0.1200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\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: 23241634\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: 79892097\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748548018482,"sku":"79892097","price":41.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d890ab6e9f9a78e9ad5fda58a302b87b.jpg?v=1788895113","url":"https:\/\/voomisupply.com\/products\/hertel-79892097-solid-carbide-jobber-drill-bit-no-31","provider":"Voomi Supply","version":"1.0","type":"link"}
