It features a 118-degree standard point angle for reliable center-finding and clean entry on flat and curved workpieces. The oxide coating helps reduce friction and provides basic corrosion resistance during use. With an overall length of 143 millimeters and a flute length of 106 millimeters, this bit delivers the reach and chip evacuation needed for typical production and maintenance drilling tasks. The straight-cylindrical shank fits standard three-jaw drill chucks. Machinists, maintenance technicians, and metal fabricators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for general-purpose drilling in light to medium-duty applications including fabrication shops, maintenance and repair operations, and production environments. It is appropriate for use in bench drill presses, hand drills, and CNC drill stations that accept straight-shank tooling. The 11.90 mm diameter, equivalent to 0.4685 inches, falls in the 10.00 to 12.50 mm size range and is commonly used for clearance holes, through-holes, and pre-tapping operations in ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e11.90 mm (0.4685 inch) drill diameter for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry on flat and rounded stock\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eOxide coating reduces friction and offers basic surface protection\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral design promotes efficient chip evacuation during drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for compatibility with standard three-jaw drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber drill bit compatible with any drill press, hand drill, or CNC drill unit equipped with a standard three-jaw chuck or collet system that accepts straight-cylindrical shanks in the 10.00 to 12.50 mm size range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in the drill chuck before operation and verify the bit runs true before engaging the workpiece. Always wear appropriate eye protection and secure the workpiece with clamps or a vise  -  never hold by hand during drilling. Select a spindle speed appropriate to the workpiece material and bit diameter following standard machining feed-and-speed references. Inspect the cutting edges before each use and remove the bit from service if chipping or deformation is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11.90 mm (0.4685 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 143 mm (5.63 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 106 mm (4.17 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: 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\u003eApplication Grade\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\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: C.402.1190\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739426292018,"sku":"C.402.1190","price":22.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fbbbc0f338ad65f12ab4b41033f8aed.jpg?v=1788814456","url":"https:\/\/voomisupply.com\/products\/hertel-c-402-1190-jobber-drill-bit-11-90mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
