Sized at 27\/64 inches (0.4219 inches) in diameter, it features a 118-degree web-thinned point that promotes self-centering and reduces thrust during entry. The bright\/uncoated carbide construction delivers the hardness and wear resistance needed for demanding materials including steel, stainless steel, cast iron, and aluminum alloys. With a spiral flute design, right-hand cut, and straight-cylindrical shank, this bit fits standard drill chucks without adapters. It is a general-purpose tool suited for production and maintenance environments where consistent hole quality is required.\u003c\/p\u003e\u003cp\u003eThis bit is built for drilling blind holes, cross holes, and through holes across a range of industrial and fabrication settings. Its primary workpiece material compatibility covers steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate, making it a versatile choice for machine shops, maintenance facilities, and toolroom use. The 220D series is a general-purpose line intended for standard drilling operations on CNC machining centers, drill presses, and manual machines where a solid carbide edge is preferred over high-speed steel for longer tool life on harder workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for improved hardness and tool life on steel and cast iron\u003c\/li\u003e\n\u003cli\u003e118-degree web-thinned point for self-centering entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish compatible with oil-based and water-soluble cutting fluids\u003c\/li\u003e\n\u003cli\u003eSpiral flute, right-hand cut for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard ER collets and keyed drill chucks\u003c\/li\u003e\n\u003cli\u003eGeneral-purpose 220D series rated for blind hole, cross hole, and self-centering applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose solid carbide jobber drill bit compatible with standard straight-shank drill chucks, ER collet systems, and drill press quills accepting a 27\/64-inch shank.

Always power down and lock out the machine spindle before inserting or removing the bit. Secure the straight-cylindrical shank firmly in the chuck or collet to the full grip depth to prevent slippage under load. This bit does not support coolant-through delivery; apply cutting fluid externally as appropriate for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 27\/64 inches (0.4219 inches \/ 10.72 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 73.00 mm (approximately 2.874 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 114.30 mm (approximately 4.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003eSeries\u003c\/strong\u003e: 220D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 220-4219\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729892180274,"sku":"220-4219","price":153.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4a25cb6fca78423402be763ec42128e_9f15d81e-c3a5-4f81-a6bf-8428c94a0ce7.jpg?v=1788709744","url":"https:\/\/voomisupply.com\/products\/osg-220-4219-solid-carbide-jobber-drill-bit-27-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
