Built from solid carbide throughout, it delivers the rigidity and edge retention needed for production drilling in ferrous and non-ferrous materials. The bright, uncoated finish suits applications where coating compatibility or post-process inspection matters. Two spiral flutes with a regular helix evacuate chips efficiently through a 2.125-inch flute length. Overall length is 3.5 inches. The straight-cylindrical shank fits standard drill chucks without adapters. Machinists, maintenance technicians, and fabricators working with CNC machines or drill presses are the typical end users.\u003c\/p\u003e\u003cp\u003eThe OSG 220-2610 is rated for general-purpose drilling in a broad range of workpiece materials including steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate. Typical operations include blind-hole drilling, cross-hole drilling, standard through drilling, and self-centering applications. The web-thinned point reduces thrust force at entry, making it well suited for hand-fed setups and programmed CNC cycles alike. This bit belongs to OSG Series 220D and covers the 0.2500 to 0.3000 decimal-inch size range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior hardness and wear resistance versus high-speed steel\u003c\/li\u003e\n\u003cli\u003e118-degree web-thinned point reduces entry thrust and improves self-centering behavior\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with a wide range of cutting fluids and workpiece materials\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral design promotes consistent chip evacuation in blind and through holes\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without requiring a reducer or adapter\u003c\/li\u003e\n\u003cli\u003eSuitable for blind-hole, cross-hole, through-drilling, and self-centering tool applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill for use in CNC machining centers, drill presses, and handheld drill setups capable of accepting a straight-cylindrical shank.

Secure the straight-cylindrical shank firmly in a calibrated chuck before operation and verify runout is within acceptable limits. Confirm spindle speed and feed rate are appropriate for the workpiece material and bit diameter before initiating a cut. This bit does not support coolant-through delivery; apply cutting fluid externally as required by the workpiece material and operation type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2610 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 6.63 mm\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\u003eDrill Bit 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.125 inches (54.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches (88.90 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: 6.63 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.013 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\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: 0.078 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: 220-2610\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743700222258,"sku":"220-2610","price":60.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5ffed366719576b47332190bfab7a45.jpg?v=1788849321","url":"https:\/\/voomisupply.com\/products\/osg-220-2610-solid-carbide-jobber-drill-bit-letter-g","provider":"Voomi Supply","version":"1.0","type":"link"}
