An oxide coating reduces friction and helps resist heat buildup during drilling. The two-flute, right-hand spiral flute geometry provides efficient chip evacuation in a wide range of metal-cutting applications. Overall length is 140.00 mm (5.5118 inches) with a flute length of 103.00 mm (4.0551 inches). The straight-cylindrical shank fits standard three-jaw drill chucks without additional toolholding adapters. This bit is sized in the 0.4000 to 0.5000 inch decimal range, making it a general-purpose choice for machinists, maintenance technicians, and fabricators.\u003c\/p\u003e\u003cp\u003eThe C.402.1080 is suited for drilling steel and cast iron in general-purpose machining and maintenance environments. Typical applications include through-hole and blind-hole drilling in structural steel, mild steel plate, and gray cast iron components. The jobber-length format provides a balance of rigidity and reach appropriate for bench drill presses, CNC machining centers, and handheld drill motors. Coolant-through capability is not featured on this bit, so flood or mist coolant applied externally at the cutting zone is recommended for sustained production drilling cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10.80 mm (0.4252 inch) diameter in the 0.4000 to 0.5000 inch size range\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose entry into steel and cast iron\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides toughness across a range of workpiece hardness levels\u003c\/li\u003e\n\u003cli\u003eOxide coating reduces friction and helps extend cutting edge life\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute design promotes clean chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill bit for use in standard three-jaw drill chucks accepting straight-cylindrical shanks, suited for steel and cast iron workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, maintenance mechanics, or fabricators using a drill press, machining center, or handheld drill motor. Secure the straight shank fully in the chuck and verify runout before beginning a cut. Power down and de-energize the machine before changing or inspecting the bit. Apply external cutting fluid or mist coolant when drilling in production volumes to manage heat and extend tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 10.80 mm (0.4252 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 140.00 mm (5.5118 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 103.00 mm (4.0551 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\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: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize Range\u003c\/strong\u003e: 0.4000 to 0.5000 inches (10.00 to 12.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: C.402.1080\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743992545586,"sku":"C.402.1080","price":23.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/677dc7b974d337aaf42648ff3be68d68.jpg?v=1788852535","url":"https:\/\/voomisupply.com\/products\/hertel-c-402-1080-jobber-drill-bit-10-80mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
