Built from vanadium high speed steel and finished with a titanium nitride (TiN) coating, the bit delivers extended tool life and reduced friction across a wide range of workpiece materials. The 120-degree S-thinned point promotes self-centering entry and reduces the thrust force required to start a hole. With an overall length of 91 mm and a 4.6 mm cutting diameter, it is suited for production drilling environments where consistent hole quality and tool longevity are priorities. Licensed machinists, tool-and-die shops, and maintenance technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThe OSG 62546 is rated for use on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. Its Series 1600 designation places it in OSGs high-performance jobber line. The bit handles blind hole drilling, cross-hole drilling, general drilling, and self-centering applications. The straight-cylindrical shank with a 6 mm diameter seats securely in standard drill chucks and CNC toolholders alike, making it a practical choice for both manual and automated machining setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVanadium high speed steel construction for toughness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTitanium nitride (TiN) coating reduces friction and extends cutting life\u003c\/li\u003e\n\u003cli\u003e120-degree S-thinned point for self-centering and reduced thrust\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eTapered web configuration supports rigidity across the flute length\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of plus 0 to minus 0.018 mm for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Suitable for blind hole, cross-hole, standard drilling, and self-centering operations per OSG Series 1600 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall in a properly sized drill chuck or collet matching the 6 mm straight-cylindrical shank before use. Secure the workpiece firmly and verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before starting. Inspect the cutting edge and TiN coating for wear or chipping between uses; a damaged edge reduces hole quality and can cause tool breakage. Coolant-through is not supported on this bit, so use external cutting fluid when drilling ferrous materials to manage heat buildup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.6 mm (0.1811 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 91 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 47 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: S-Thinned\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 Helix\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\u003eMaterial\u003c\/strong\u003e: Vanadium High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0 to minus 0.018 mm\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: 1600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 62546\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737540952370,"sku":"62546","price":56.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe3c24709eaf2ae70e5a882c1e030604.jpg?v=1788790058","url":"https:\/\/voomisupply.com\/products\/osg-62546-jobber-drill-bit-4-6mm-tin-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
