It measures 0.404 inches (Letter Y, 10.26 mm) in diameter with an overall length of 4-1\/32 inches and a flute length of 1-15\/16 inches. Built from cobalt high speed steel with a coated finish, this bit handles demanding materials that standard HSS tooling cannot. The 130-degree split point and R-thinned web reduce thrust and improve penetration in tough ferrous stock. A tapered web configuration adds rigidity and supports the 3xD flute-to-diameter ratio typical of screw machine length tooling.\u003c\/p\u003e\u003cp\u003eScrew machine length drill bits are the standard choice when rigidity matters more than depth reach. This bit is suited for CNC machining centers, drill presses, and screw machines running production runs in steel and alloy steel. The shorter flute length relative to jobber bits minimizes deflection in interrupted cuts and close-tolerance hole work. Machinists and toolroom technicians running ferrous workpieces in light to medium manufacturing environments will find this a practical, high-performance option.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high speed steel construction for improved heat and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle for reduced thrust and cleaner entry on hard steel\u003c\/li\u003e\n\u003cli\u003eR-thinned web reduces cutting resistance at the chisel edge\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders without adapters\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with 3xD ratio provides chip clearance in screw machine length format\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, two-flute spiral design compatible with conventional CNC and manual spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine length drill bit for Series 1000 tooling applications targeting steel and alloy steel primary workpiece materials with straight-cylindrical shank tool holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or toolroom technicians familiar with cutting tool setup. Secure the straight-cylindrical shank fully in the chuck or collet before operation, and verify runout with a dial indicator on precision work. Power down and de-energize the spindle before changing tooling. Follow shop safety practices and applicable OSHA machine guarding standards when operating drill presses or CNC equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.404 inches (Letter Y \/ 10.26 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-15\/16 inches (49.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel\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 to -0.027 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.171 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10404005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749570052402,"sku":"10404005","price":113.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/529a02c582e209cb7c5c63bbeebbad14_b14a97c7-2ae9-4a13-bc9b-bf55af3f1327.jpg?v=1788907757","url":"https:\/\/voomisupply.com\/products\/osg-10404005-screw-machine-drill-bit-0-404-in-cobalt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
