At 0.191 inches (wire size #11, 4.85 mm) in diameter, it features a 135-degree split point with web thinning for fast, accurate starts with minimal walking. The spiral flute geometry and slow spiral type are optimized for chip evacuation in deep-hole drilling. The straight-cylindrical shank seats securely in standard drill chucks and collets. This bit is intended for use by machinists, tool-and-die workers, and maintenance technicians requiring consistent, repeatable hole tolerance in production environments.\u003c\/p\u003e\u003cp\u003eThe 215-1910 is suited for drilling steel, alloy steel, stainless steel, cast iron, aluminum silicate, nickel alloy, titanium, and titanium alloys. Its general-purpose performance rating makes it appropriate for job shop, maintenance, and light production drilling where a single bit must handle a range of ferrous and non-ferrous workpiece materials. The 5xD flute-to-diameter ratio supports drilling in moderate-depth applications without excessive deflection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e135-degree standard point with web thinning and tapered web configuration for self-centering entry\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute design promotes controlled chip flow in steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish compatible with a wide range of cutting fluids and workpiece materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with 2-flute spiral geometry for efficient chip clearance\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of plus 0 to minus 0.013 mm for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-purpose drill bit for use in any standard drill press, CNC machining center, or hand drill equipped with a straight-shank chuck or collet sized for the 11.00 mm shank diameter.

Ensure the machine spindle is fully stopped and locked out before changing or inspecting the bit. Confirm chuck or collet runout is within acceptable limits before drilling, as carbide is brittle and sensitive to side-loading. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain hole tolerance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1910 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: #11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 4.85 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Slow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/16 inches (30.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 11.00 mm\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: plus 0 to minus 0.013 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Alloy Steel, Stainless Steel, Cast Iron, Aluminum Silicate, Nickel Alloy, Titanium, Titanium Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 215\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.033 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 215-1910\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738385744178,"sku":"215-1910","price":48.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61bd3e9d6baf39e70a6f7df18cd13940.jpg?v=1788798919","url":"https:\/\/voomisupply.com\/products\/osg-215-1910-screw-machine-drill-bit-0-191-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
