Turned from high speed steel with a coated finish, this bit features a 120-degree faceted drill point and a right-hand spiral flute configuration with web thinning for improved chip evacuation and reduced thrust. The straight-cylindrical shank measures 10 millimeters in diameter, allowing secure seating in standard drill chucks and CNC toolholders. At 0.323 inches (8.20 mm) in diameter, the bit targets letter-size P drilling applications and is built to OSG Series 1150 specifications for consistent performance across repeated use in production settings.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in screw machine operations, CNC machining centers, and benchtop drill press work where a compact, stubby geometry is preferred over jobber length. The shortened flute length reduces deflection in close-tolerance bores. The coated high speed steel construction handles steel, alloy steel, aluminum, aluminum alloy, and aluminum silicate workpiece materials without requiring through-coolant. It is typically installed by machinists, tool-and-die technicians, and maintenance mechanics running production drilling cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.323 inch (8.20 mm) diameter with a tight tolerance of +0 to -0.022 mm for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003e120-degree faceted drill point with web thinning reduces entry thrust and improves centering\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry with tapered web configuration promotes chip clearing\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length body limits deflection in short-reach drilling setups\u003c\/li\u003e\n\u003cli\u003eCoated high speed steel construction extends tool life across steel, alloy steel, and aluminum workpieces\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard chucks and collet toolholders without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on steel, alloy steel, aluminum, aluminum alloy, and aluminum silicate workpieces.

Secure the straight-cylindrical shank in a properly sized collet or drill chuck to the full recommended grip depth before running. Inspect the cutting edges and coating for wear or chipping before each use, and replace the bit if the point geometry is compromised to avoid oversized or off-center holes. This tool does not require through-coolant, but flood or mist cooling is appropriate for extended production runs.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3230 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 8.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 87.00 mm (approximately 3.43 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 37.00 mm (approximately 1.46 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: 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\u003ePoint Type\u003c\/strong\u003e: Faceted\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\u003eSeries\u003c\/strong\u003e: 1150\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: 11559915\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753826287922,"sku":"11559915","price":100.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed03926075131be36795afdda21816b9_110b09c5-8250-4ea3-b1a6-c5169519b949.jpg?v=1788941173","url":"https:\/\/voomisupply.com\/products\/osg-11559915-screw-machine-drill-bit-0-323-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
