It carries a wire gauge size of No. 52, which corresponds to a decimal diameter of 0.0635 inches, held to a tight tolerance of +0.0000 to -0.0005 inches. The 140-degree notched point geometry and web-thinned construction reduce thrust force at entry, supporting accurate hole placement in hard and difficult-to-machine materials. With a bright, uncoated finish and C2 carbide grade, this bit is suited for shops and field machinists who need reliable performance without a coated tool premium.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in ferrous and specialty alloy materials including steel, stainless steel, heat-treated alloy steel, chrome alloy, nickel alloy, and titanium alloy. Right-hand cutting direction makes it compatible with standard CNC machining centers, drill presses, and hand-held drill motors turning in conventional forward rotation. The straight-flute configuration is particularly effective in short-chipping materials where chip evacuation along spiral flutes is unnecessary. Coolant-through capability is not supported on this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in C2 material grade for rigidity and wear resistance in hard metals\u003c\/li\u003e\n  \u003cli\u003eNo. 52 wire size at 0.0635 inch diameter with a diameter tolerance of +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e140-degree notched point reduces walking and improves entry accuracy on hard surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned design lowers axial thrust, reducing heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eStraight two-flute geometry suits short-chipping alloys including stainless and titanium\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish allows direct visual inspection of cutting edge condition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide drill for applications requiring a No. 52 wire gauge hole in ferrous and specialty alloy workpieces on standard drill press or CNC spindle setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool should be installed by a qualified machinist or tooling technician familiar with carbide drill handling. Secure the shank firmly in a collet or chuck rated for the 0.0635-inch diameter to prevent runout, which is particularly damaging to small-diameter carbide tools. Ensure the machine spindle is at a full stop before changing or inspecting the bit. Avoid side loading or flexing the tool during use, as solid carbide is rigid but brittle and will fracture under lateral stress.\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: No. 52\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal)\u003c\/strong\u003e: 0.0635 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0635 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\u003eCompatible 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: 83246157\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731618365746,"sku":"83246157","price":30.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4dd52806669bd2d4e09374fdb658771f.jpg?v=1788733237","url":"https:\/\/voomisupply.com\/products\/hertel-83246157-straight-flute-drill-bit-no-52-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
