Built from solid carbide with a bright\/uncoated finish, it delivers consistent performance in general-purpose drilling applications across a wide range of workpiece materials. The right-hand spiral flute geometry promotes efficient chip evacuation, and the straight-cylindrical shank seats reliably in standard drill chucks and CNC tool holders. With an overall length of approximately 3.999 inches (101.60 mm) and a flute length of 2.500 inches (63.50 mm), this bit is sized for the reach and rigidity typical of jobber-series tooling.\u003c\/p\u003e\n\u003cp\u003eThe 220-3438 is well suited for blind hole drilling, cross-hole drilling, self-centering operations, and standard through-hole work. Its Series 220D construction targets general-purpose metal-cutting environments, making it a practical choice for machine shops, maintenance facilities, and fabrication operations where a reliable carbide bit is needed across mixed-material workloads. The 2-flute, regular spiral configuration handles both ferrous and non-ferrous stock without requiring coolant-through tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life compared to high-speed steel in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e118-degree web-thinned point reduces entry thrust and improves self-centering performance\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use across ferrous and non-ferrous workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute promotes consistent chip flow in blind and through-hole applications\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0 to -0.013 mm supports close-tolerance hole requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate workpiece materials (material codes P, M, K, N). Designed for use in blind hole, cross-hole, drilling, and self-centering tool applications as part of the OSG Series 220D general-purpose carbide drill line.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists and toolroom technicians in drill presses, machining centers, and CNC lathes. Ensure the shank is fully seated and the chuck or collet is tightened to the tool holder manufacturer's specification before operation. Coolant-through is not supported on this model; apply external flood or mist coolant as required by the workpiece material and cutting parameters. Inspect the cutting edge for chipping before each use, as carbide tooling is brittle and susceptible to damage from improper handling or interrupted cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/32 inch (0.3438 inch \/ 8.73 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\u003eMaterial\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\u003eOverall Length\u003c\/strong\u003e: 101.60 mm (approximately 3.999 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 63.50 mm (approximately 2.500 inches)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.013 mm\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: 0.225 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 220-3438\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728506945842,"sku":"220-3438","price":101.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4a25cb6fca78423402be763ec42128e_3dab9c42-7866-4658-a6a7-7deefc22258a.jpg?v=1788692342","url":"https:\/\/voomisupply.com\/products\/osg-220-3438-jobber-drill-bit-11-32-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
