It features a 140-degree notched point with web thinning for reduced thrust and cleaner entry. The C2 carbide grade provides hardness and wear resistance suited to demanding materials. This bit runs with right-hand cutting direction, has two flutes, and carries a bright\/uncoated finish. It is engineered for production drilling in machining centers, CNC setups, and manual drill presses where tight tolerances and material hardness require a solid carbide tool over high-speed steel alternatives.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in ferrous and high-alloy materials including stainless steel, chrome alloy, heat-treated alloy, nickel alloy, plain steel, and titanium alloy. Its web-thinned geometry reduces the force needed to penetrate tough work materials, making it a practical choice in aerospace, defense, energy, and precision-manufacturing applications. The 0.2090-inch diameter is equivalent to a Wire Size 4 drill, a common sizing specification in tooling layouts for precision bore work. Diameter tolerance is held to plus 0.0000 and minus 0.0005 inches for consistent, repeatable hole sizing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide C2 grade construction for hardness and extended tool life in ferrous and alloy materials\u003c\/li\u003e\n  \u003cli\u003e140-degree notched point geometry reduces walking and improves centering on entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned design lowers axial thrust and cutting force in hard or work-hardening materials\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with standard cutting fluids and coolants\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute configuration for standard drill press and CNC spindle setups\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of plus 0.0000 to minus 0.0005 inches supports close-tolerance bore applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling chrome alloy, heat-treated alloy, nickel alloy, stainless steel, plain steel, and titanium alloy workpieces.

Verify chuck or collet runout before seating the bit, as excessive runout accelerates carbide breakage. Always bring spindle speed and feed rate within the range recommended for carbide tooling in the specific workpiece material before engaging the cut. Do not use this bit in handheld drilling applications, as carbide is brittle and susceptible to fracture under lateral loading.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal)\u003c\/strong\u003e: 0.2090 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2090 inches\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\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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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\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\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0.0000 to minus 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\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\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: 83246637\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749473681714,"sku":"83246637","price":48.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e02307b81b00d096ba2ef90c7dd3ffe6.jpg?v=1788906524","url":"https:\/\/voomisupply.com\/products\/hertel-83246637-straight-flute-drill-bit-wire-4-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
