It belongs to OSG Series 220D and is built for general-purpose drilling in a wide range of ferrous and non-ferrous materials. The bright, uncoated finish suits applications where coating compatibility with workpiece material or cutting fluid chemistry is a consideration. With an overall length of 3.25 inches and a 2-inch flute length, this bit fits standard drill chucks and CNC toolholders with a straight-cylindrical shank. Machinists, tool-and-die technicians, and maintenance mechanics install this type of bit in both manual and CNC drilling operations.\u003c\/p\u003e\u003cp\u003eThe 220-2380 is suited for blind-hole drilling, cross-hole drilling, and self-centering applications across production and job-shop environments. Primary target materials include steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate. The regular spiral flute promotes chip evacuation in these materials without requiring through-spindle coolant. This bit fits the typical jobber-length reach requirements in light to medium drilling work on machining centers, drill presses, and hand-held power tools.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eLetter B diameter (0.2380 inch \/ 6.05 mm) with a tight tolerance of +0 to -0.013 mm\u003c\/li\u003e\n\u003cli\u003e118-degree web-thinned point reduces entry thrust and supports self-centering starts\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with tapered web configuration promotes chip flow in blind and cross-hole applications\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — compatible with most cutting fluids without coating interaction concerns\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2-flute design suitable for drilling steel, stainless, cast iron, aluminum, and aluminum alloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in standard straight-shank chucks and CNC toolholders.

Power down the machine and lock out energy sources before changing tooling per OSHA lockout-tagout requirements. Carbide is brittle — avoid lateral loading, interrupted cuts without proper feed adjustment, or dropping the bit on hard surfaces. Verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before starting the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2380 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 6.05 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Web-Thinned\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2 inches (50.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches (82.60 mm)\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: 6.05 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Finish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.013 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole, Cross Hole, Drilling, Self-Centering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Alloy Steel, Stainless Steel, Cast Iron, Aluminum, Aluminum Alloy, Aluminum Silicate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 220D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: 220-2380\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727736471858,"sku":"220-2380","price":52.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d0b30a83daea5ca41b77d1416284ecf.jpg?v=1788681438","url":"https:\/\/voomisupply.com\/products\/osg-220-2380-solid-carbide-jobber-drill-bit-letter-b","provider":"Voomi Supply","version":"1.0","type":"link"}
