Built from solid carbide at material grade C2, this bit holds a 0.1285-inch diameter corresponding to a wire size 30 designation. The 140-degree notched point and web-thinned geometry reduce thrust force on entry and improve centering accuracy. Two right-hand cutting flutes remove chips efficiently in short-chipping ferrous materials. The bright, uncoated finish suits applications where coating interaction with the workpiece material is a concern. This bit is intended for use by machinists and metal fabricators working with precision drilling equipment.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling chrome alloy, heat-treated alloy, nickel alloy, stainless steel, carbon steel, and titanium alloy materials. It is a strong fit for production and maintenance machining environments where tight-tolerance holes are required in hard metals. The straight-flute design is particularly effective in materials that produce short chips, such as cast iron and hardened steels, where standard helical flutes can pack and bind.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction at grade C2 for rigidity and wear resistance in hard metals\u003c\/li\u003e\n\u003cli\u003e140-degree notched point for reduced entry thrust and improved self-centering\u003c\/li\u003e\n\u003cli\u003eWeb-thinned geometry reduces cutting force and heat buildup at the tip\u003c\/li\u003e\n\u003cli\u003eStraight-flute design optimized for short-chipping ferrous and exotic alloy materials\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches for consistent, close-tolerance hole sizing\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for applications sensitive to coating contamination\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard drill chucks and collet systems accepting a 0.1285-inch shank diameter.

Secure the shank fully in a precision drill chuck or collet before operation, and verify runout before beginning a cut. Carbide is brittle compared to high-speed steel — avoid side loading, interrupted cuts without proper setup, and impact from improper chuck engagement. Follow machine manufacturer guidelines for spindle speed and feed rate for the specific workpiece material and hole diameter.\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\u003eWire Size\u003c\/strong\u003e: 30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal)\u003c\/strong\u003e: 0.1285 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1285 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\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\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\u003eCoolant Through\u003c\/strong\u003e: No\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\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: 83246371\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728870605106,"sku":"83246371","price":30.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/118de3fce7d85e8fc64ff3a26eae1a54.jpg?v=1788697178","url":"https:\/\/voomisupply.com\/products\/hertel-83246371-straight-flute-drill-bit-30-wire-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
