It measures 11.10 mm (0.4370 inches) in diameter with a 118-degree standard point angle, providing a versatile cutting geometry suited to a wide range of materials and applications. The bit features a right-hand spiral flute configuration and an oxide coating that reduces friction and helps extend tool life under normal shop conditions. At 140.00 mm overall length with a 103.00 mm flute length, it delivers the reach and chip-clearing capacity expected of a jobber-length drill. Machinists, maintenance technicians, and fabricators are the typical end users.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use in drill presses, lathes, and handheld power drills where a straight-cylindrical shank is compatible. Its general-purpose grade makes it appropriate for light to medium-duty production work, maintenance and repair operations, and job-site drilling tasks. The 0.4370-inch decimal equivalent places it within the 0.4000 to 0.5000 inch size range, making it a common selection when drilling clearance or pilot holes in structural and fabricated assemblies. No coolant-through capability is present, so standard flood or mist cooling should be applied externally when drilling ferrous materials at higher speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e11.10 mm (0.4370 inch) diameter with 118-degree standard point for versatile material entry\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides toughness across general-purpose drilling applications\u003c\/li\u003e\n\u003cli\u003eOxide coating reduces friction and aids in heat dissipation during cutting\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute design promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank seats securely in standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003e140.00 mm overall length with 103.00 mm flute length for adequate reach and clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with standard drill chucks and holders that accept a straight-cylindrical shank in the 11.10 mm diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by machinists or qualified technicians familiar with rotating cutting tools. Ensure the workpiece is securely clamped and the drill is properly seated and tightened in the chuck before operation. Apply appropriate cutting fluid or coolant externally when drilling steel or other ferrous materials to manage heat buildup. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point geometry is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11.10 mm (0.4370 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 140.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 103.00 mm\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: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: C.402.1110\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743340298546,"sku":"C.402.1110","price":19.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/100dfcb884cf7aedfc465926decf9235.jpg?v=1788845859","url":"https:\/\/voomisupply.com\/products\/hertel-c-402-1110-jobber-drill-bit-11-10mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
