Built to Series 220D specifications, it features a 118-degree web-thinned point that reduces thrust and improves self-centering on entry. The bright, uncoated finish is standard for solid carbide tooling used in a wide range of ferrous and non-ferrous materials. With an overall length of 3.25 inches and a 2-inch spiral flute, this bit delivers reliable chip evacuation in general-purpose drilling operations. Machinists and tool-and-die technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThe 220-2460 is suited for drilling blind holes, cross holes, and through holes in steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloys, and aluminum silicate. It runs in standard CNC machining centers, drill presses, and manual lathes where a straight-cylindrical shank and right-hand cutting direction are required. The regular spiral type handles general-purpose stock removal without the need for coolant-through capability, making it a practical choice for job-shop and production environments alike.\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 workpiece materials\u003c\/li\u003e\n\u003cli\u003e118-degree web-thinned point reduces entry thrust and promotes self-centering\u003c\/li\u003e\n\u003cli\u003eLetter D diameter (0.2460 inch \/ 6.25 mm) with tight tolerance of +0 to -0.013 mm\u003c\/li\u003e\n\u003cli\u003e2-inch spiral flute length with regular helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, straight-cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks and collet systems accepting a 6.25 mm straight-cylindrical shank.

Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. Do not exceed the recommended feed and speed parameters for the workpiece material and machine setup. Inspect the cutting edges before each use and remove from service if chipping or wear is observed, as solid carbide is brittle and sensitive to side loading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2460 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 6.25 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: 6.25 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\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.013 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 0.14 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: 220-2460\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737745129778,"sku":"220-2460","price":67.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4a25cb6fca78423402be763ec42128e_520526a4-0801-4913-a510-897d8a209e3f.jpg?v=1788793073","url":"https:\/\/voomisupply.com\/products\/osg-220-2460-solid-carbide-jobber-drill-bit-letter-d","provider":"Voomi Supply","version":"1.0","type":"link"}
