It carries a wire gauge size of 77, corresponding to a decimal diameter of 0.0180 inches, and features a standard 118-degree drill point angle with web thinning for easier penetration. The bright finish leaves the carbide surface uncoated for general-purpose work. At 0.75 inches overall length with a 0.1875-inch flute length, this bit is suited for close-tolerance drilling in hard or abrasive materials where high-speed steel would wear prematurely. Machinists, tool-and-die workers, and precision fabricators are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThis bit is used in CNC drilling centers, drill presses, and precision hand-held spindle applications where tight diameter tolerances are required. The C2 carbide grade makes it appropriate for cast iron, hardened steel, composites, and other abrasive workpiece materials. Its straight-cylindrical shank seats directly in standard collets and chucks compatible with 0.0180-inch shank diameters. The regular spiral flute geometry promotes chip evacuation in short-depth holes typical of its flute length. It is sold individually and is well suited to production environments that require consistent, repeatable small-hole geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide C2 grade construction for superior wear resistance over HSS in abrasive materials\u003c\/li\u003e\n  \u003cli\u003eWire size 77 — 0.0180-inch decimal diameter for precise small-bore work\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning reduces thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with tapered web configuration promotes chip flow in short holes\u003c\/li\u003e\n  \u003cli\u003eBright finish — no coating interference on tight-tolerance features\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for direct chuck or collet mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in any spindle, collet, or drill chuck accepting a 0.0180-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit should be installed by a qualified machinist or tooling technician familiar with small-diameter carbide tooling. Ensure the spindle and chuck are clean and concentric before seating the shank, as runout is especially damaging to carbide at this diameter. Carbide is brittle — avoid side loading, interrupted cuts without appropriate feed reduction, or using the bit as a reamer. Follow machine manufacturer feed and speed recommendations for carbide tooling at this diameter range.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 77\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0180 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit 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\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eFlute Length\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\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: 0.0180 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\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\u003eWeight\u003c\/strong\u003e: 0.1 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: 83246017\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734799941938,"sku":"83246017","price":24.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72f489785cc4ef902b7594139899adbb.jpg?v=1788767019","url":"https:\/\/voomisupply.com\/products\/hertel-83246017-carbide-jobber-drill-bit-wire-77","provider":"Voomi Supply","version":"1.0","type":"link"}
