Built from cobalt high speed steel with a coated finish, this bit handles demanding materials where standard high speed steel dulls prematurely. It features a 0.323 inch (letter size P, 8.20 mm) cutting diameter, a 130-degree point angle for self-centering starts, and a right-hand spiral flute configuration. At 3.5 inches overall length, it fits standard screw machine and production drilling setups. Licensed machinists, tool-and-die technicians, and industrial maintenance mechanics are the typical installers.\u003c\/p\u003e\u003cp\u003eThis bit is suited for short-hole production drilling in steel and alloy steel workpieces. The screw machine length profile keeps the bit rigid and reduces deflection in CNC drill presses, turret lathes, and automatic screw machines. The 3xD flute-to-diameter ratio and tapered web with R-thinning improve chip evacuation and reduce thrust in tighter drilling cycles. It fits any standard straight-shank chuck.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high speed steel construction for extended tool life in steel and alloy steel\u003c\/li\u003e\n\u003cli\u003e130-degree point angle for aggressive, self-centering entry\u003c\/li\u003e\n\u003cli\u003eR-thinned, tapered web reduces thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length for maximum rigidity and minimal deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine drill bit for production and maintenance drilling in steel and alloy steel workpieces using any standard straight-shank chuck with 0.323 inch capacity.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance mechanics in machine shop or industrial maintenance environments. Secure the shank fully in the chuck and verify runout before drilling. Use appropriate cutting fluid or coolant for steel to extend tool life, noting this bit does not support coolant-through operation. Follow applicable shop safety standards for rotating tooling, including proper workpiece clamping and eye protection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.323 inches (Letter P, 8.20 mm)\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 (42.00 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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.022 mm\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\u003eSeries\u003c\/strong\u003e: 1000\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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10323005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749293719858,"sku":"10323005","price":90.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84857de33cd2d96fb33961f8897b7eaf.jpg?v=1788904169","url":"https:\/\/voomisupply.com\/products\/osg-10323005-screw-machine-drill-bit-0-323-in-cobalt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
