Built from Cobalt Vanadium High Speed Steel with a bright, uncoated finish, this bit measures 0.413 inches in diameter with an overall length of 3.5 inches and a flute length of 1.6875 inches. The 130-degree split point reduces walking and decreases feed force on entry. A parabolic flute geometry promotes efficient chip evacuation, making it well suited for deep-hole and production drilling. Straight-cylindrical shank construction ensures secure chuck engagement in standard drill presses and hand-held power tools. Licensed tradespeople and machinist-level technicians are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis bit is engineered for universal performance across a wide range of workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals. Screw machine length geometry keeps the bit compact and rigid, reducing deflection in short-reach applications and production environments. The parabolic flute-to-diameter ratio of 3xD supports consistent chip flow at the maximum drilling depth of 1.1 inches. The web-thinned, tapered web configuration lowers cutting resistance and extends tool life in repetitive drilling cycles. This bit is appropriate for both job-shop use and CNC or manual drill press operations where tight diameter tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt Vanadium High Speed Steel construction for elevated heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e130-degree split point reduces drill walking and minimizes entry burr\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design promotes aggressive chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web lowers cutting resistance and reduces required feed force\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets DIN, ISO, and BS specification standards for dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style screw machine length drill bit suitable for use with standard three-jaw drill chucks on drill presses, CNC machining centers, and handheld power tools accepting straight-cylindrical shanks in the 0.413-inch diameter range.

Secure the shank fully in the chuck jaws and verify runout before beginning a drilling cycle. Always use appropriate cutting fluid or lubricant for the workpiece material to preserve edge life, particularly when drilling stainless steel or hard alloys. Power down and de-energize the machine spindle completely before changing or inspecting the bit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.413 inches (Letter Size Z)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.6875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0963 inches\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: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Web-Thinned, Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt Vanadium High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Cast Iron, Hard Material, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.00106 to 0.00000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: Universal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A1148\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN, ISO, BS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: WALTER-TITEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5153739\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51743994118450,"sku":"5153739","price":245.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d778e31de38b3101e5d48fe228b3dfd1_7dac362c-611b-418a-b0e7-6cd84a767d6d.jpg?v=1788852569","url":"https:\/\/voomisupply.com\/products\/walter-titex-5153739-screw-machine-drill-bit-0-413-in","provider":"Voomi Supply","version":"1.0","type":"link"}
