The bit measures 11\/32 inches (0.3438 inches) in diameter with a 3-inch overall length and a 1-11\/16 inch flute length. A 135-degree split point provides self-centering entry without a center punch, reducing walking on hard or smooth metal surfaces. The web-thinned, parallel web configuration lowers cutting resistance and improves chip evacuation. This bit is installed by machinists, tool and die technicians, and industrial maintenance trades working in production drilling setups or manual drill press operations.\u003c\/p\u003e\n\u003cp\u003eScrew machine length bits are shorter than jobber-length bits, making them the preferred choice where rigidity and reduced deflection matter — such as drilling in lathes, CNC turrets, screw machines, and short-travel drill press fixtures. The 11\/32-inch diameter is commonly used for tapping prep holes and through-hole work in steel, stainless steel, cast iron, and other ferrous materials. The cobalt construction handles elevated cutting temperatures that would degrade standard high-speed steel tooling. Straight shank geometry fits standard drill chucks and collet holders without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt (HSCO) construction for heat resistance in ferrous metal drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for self-centering entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web reduces cutting resistance and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (3 inches OAL) provides added rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with right-hand cutting direction for standard drill press and CNC use\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or new-install cobalt screw machine drill bit for any standard 3-jaw chuck or collet system accepting a straight cylindrical shank in the 11\/32-inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in the chuck or collet before use and verify runout before engaging the workpiece. Always power down the drill press or CNC spindle and lock out energy sources before changing tooling. Use appropriate cutting fluid for ferrous metals to extend tool life and control heat buildup. Follow applicable ANSI and shop-floor safety standards for rotating cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/32 inches (0.3438 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (HSCO)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HSCO135\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.36 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 74130337\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729529176370,"sku":"74130337","price":20.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6430a3fb26e3ca2c17d4e4e087353be0.jpg?v=1788705781","url":"https:\/\/voomisupply.com\/products\/hertel-74130337-cobalt-screw-machine-drill-bit-11-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
