It measures 11\/32 inches (0.3438 inches decimal) in diameter and features a 140-degree notched point geometry that reduces thrust and improves centering on entry. The web-thinned design lowers cutting resistance on difficult materials. Right-hand cutting direction is standard. Bright\/uncoated finish maintains the as-ground carbide edge without additional coating layers. Machinist and tool crib personnel are the primary users. Diameter tolerance is held to +0.0000 to -0.0005 inches for close-tolerance work.\u003c\/p\u003e\u003cp\u003eThis bit is engineered for drilling chrome alloy, heat-treated alloy, nickel alloy, stainless steel, carbon steel, and titanium alloy. The 140-degree notched point and web thinning make it particularly well-suited for stainless and high-nickel alloys where conventional geometry drills tend to work-harden the material and walk on entry. The C2 carbide grade balances hardness and toughness for a broad range of ferrous and exotic-metal applications in production machining and maintenance environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction, C2 material grade, for drilling hard and abrasion-resistant metals\u003c\/li\u003e\n\u003cli\u003e140-degree notched point reduces thrust and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned flute design lowers cutting resistance in tough alloys\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish preserves as-ground edge geometry\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction; 2-flute configuration for chip clearance\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches supports close-tolerance hole requirements\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 an 11\/32-inch straight shank.

Secure the shank fully in the chuck or collet before operation and verify runout before cutting. Carbide is brittle  -  avoid interrupted cuts or side-loading that can chip the cutting edge. Ensure the machine spindle is stopped completely before changing or inspecting the bit.\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 Diameter (Fractional)\u003c\/strong\u003e: 11\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal)\u003c\/strong\u003e: 0.3438 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\u003eShank Diameter (Fractional)\u003c\/strong\u003e: 11\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal)\u003c\/strong\u003e: 0.3438 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\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\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 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: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: 74129297\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740282093874,"sku":"74129297","price":79.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3aee5fc36706876bf9e550e54e451431.jpg?v=1788823984","url":"https:\/\/voomisupply.com\/products\/hertel-74129297-straight-flute-drill-bit-11-32-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
