Built from solid carbide at material grade C2, it carries a 140-degree notched point with web thinning for reduced thrust and cleaner entry. The bit measures 0.1610 inches in diameter, corresponding to wire gauge size 20, with a shank diameter of 0.1610 inches. A bright, uncoated finish keeps the carbide sharp and ready for dry or flood-coolant applications. Two right-hand flutes evacuate chips efficiently on short-run and production drilling operations. Licensed machinists, tool-and-die technicians, and precision metalworking shops are the primary installers.\u003c\/p\u003e\u003cp\u003eThis bit is rated for primary and secondary use on chrome alloy, heat-treated alloy, nickel alloy, stainless steel, carbon steel, and titanium alloy workpieces. It is well suited to aerospace, automotive, and industrial manufacturing environments where tight hole tolerances are required. The diameter tolerance of +0.0000 to -0.0005 inches supports close-fit fastener holes and precision bore work. Coolant-through capability is not included, so adequate surface or flood cooling should be planned when drilling deep holes or continuous production runs in heat-sensitive alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide C2 grade construction for hardness and wear resistance in ferrous and exotic alloys\u003c\/li\u003e\n\u003cli\u003e140-degree notched point reduces walking and improves penetration on hard materials\u003c\/li\u003e\n\u003cli\u003eWeb-thinned design lowers axial thrust and extends tool life\u003c\/li\u003e\n\u003cli\u003e0.1610-inch diameter with tight tolerance of +0.0000 to -0.0005 inches for precision fitment\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with a wide range of cutting fluids\u003c\/li\u003e\n\u003cli\u003eRight-hand, two-flute straight configuration for controlled chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks and CNC machining centers accepting a 0.1610-inch straight shank; suited for drilling chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is intended for use by qualified machinists and CNC operators familiar with carbide tooling. Secure the shank fully in a precision collet or keyless chuck before operation and verify spindle runout meets the tolerance requirements of the application. Carbide is brittle and susceptible to breakage under side-loading or interrupted cuts; avoid lateral flex during drilling. Apply appropriate cutting fluid or flood coolant when drilling deep holes or working with heat-sensitive nickel and titanium alloys.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Type\u003c\/strong\u003e: Straight-Flute\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal)\u003c\/strong\u003e: 0.1610 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1610 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Notched\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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool 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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Chrome Alloy, Heat-Treated Alloy, Nickel Alloy, Stainless Steel, Steel, Titanium Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 83246470\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":67913553641778,"sku":"83246470","price":44.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d5c66d14cc96bfeb64c881e52226030.jpg?v=1791246095","url":"https:\/\/voomisupply.com\/products\/hertel-83246470-straight-flute-drill-bit-wire-20-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
