Built to Series 220D specifications, it features a wire gauge No. 16 diameter of 0.1770 inches, a 118-degree drill point angle with web thinning for improved self-centering, and a 2-flute spiral configuration with a regular spiral type. The straight-cylindrical shank and bright, uncoated finish make this bit ready for direct chuck mounting without additional prep. With an overall length of 2.75 inches and a flute length of 1.625 inches, it is sized for short-reach, close-tolerance drilling tasks. Machinist technicians, maintenance mechanics, and tool-and-die professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production and maintenance drilling in steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate workpieces. The web-thinned point reduces thrust and improves chip clearing, making it practical for blind hole, cross hole, and standard through-hole drilling operations. It is a general-purpose tool appropriate for both manual drill presses and CNC machining centers where a jobber-length reach is sufficient. The diameter tolerance of plus 0 to minus 0.013 mm supports close-fit hole requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e118-degree web-thinned point promotes self-centering and reduces required thrust\u003c\/li\u003e\n  \u003cli\u003eWire gauge No. 16 diameter at 0.1770 inches with a tight tolerance of plus 0 to minus 0.013 mm\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 2-flute regular spiral for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish compatible with a wide range of cutting fluids and dry-cutting scenarios\u003c\/li\u003e\n  \u003cli\u003eRated for blind hole, cross hole, drilling, and self-centering tool applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with workpiece materials including steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate.

Secure the straight-cylindrical shank firmly in the chuck or collet before operation and verify runout before beginning a cut. Power down and de-energize the machine spindle completely before changing or inspecting the bit. Do not exceed the recommended feed and speed parameters for the workpiece material and machine type in use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1770 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 4.50 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\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\u003ePoint Type\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (Inch)\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (mm)\u003c\/strong\u003e: 69.90 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length (Inch)\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length (mm)\u003c\/strong\u003e: 41.30 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0 to minus 0.013 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\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\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\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.033 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: 220-1770\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743899287858,"sku":"220-1770","price":37.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a42ae41f9e010f1f976974ff759d04b1.jpg?v=1788851068","url":"https:\/\/voomisupply.com\/products\/osg-220-1770-solid-carbide-jobber-drill-bit-wire-16","provider":"Voomi Supply","version":"1.0","type":"link"}
