Built from solid carbide with an EgiAs coating, it operates at the elevated speeds and feeds that carbide tooling allows, delivering consistent hole quality across production runs. The 180-degree point angle provides a flat entry geometry suited for work on curved or irregular surfaces, reducing walking and improving positional accuracy. With a 4.3 mm diameter (0.1693 inch decimal equivalent) and a 6.00 mm straight-cylindrical shank, this bit is sized for precision work in CNC machining centers, drill presses, and production drilling fixtures. Licensed machinists and tool-and-die trades are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in steel, alloy steel, and cast iron workpieces. The screw machine length body, with a 21.00 mm flute length and 60.00 mm overall length (2.3622 inches), keeps the tool rigid in short-reach applications, reducing deflection and improving hole straightness. The 3xD flute-to-diameter ratio and tapered web configuration with web thinning support efficient chip evacuation. Coolant-through capability makes it compatible with machines equipped with through-spindle coolant delivery, extending tool life in continuous cutting operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003e180-degree point angle for flat entry and reduced drill walk\u003c\/li\u003e\n\u003cli\u003eEgiAs coating on drill tip for enhanced heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports through-spindle coolant delivery\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web for improved chip evacuation and reduced thrust\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, straight-cylindrical shank for standard collet and chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in steel, alloy steel, and cast iron workpieces.

Confirm the spindle and toolholder are clean and properly secured before mounting. Carbide drill bits are brittle compared to HSS tooling — avoid side loading, interrupted cuts without proper feed support, or hand-feeding on manual machines without appropriate rigidity. When using coolant-through capability, verify the machine spindle delivers adequate coolant pressure before beginning the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.3 mm (0.1693 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 60.00 mm (2.3622 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 21.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.2362 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 180 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: EgiAs (tip coating)\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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5720\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 3334319\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731789644082,"sku":"3334319","price":162.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1009c2e4540f28444916b42e80c3ac5_dacc6ebc-1ce9-425c-947f-d9e21732fcac.jpg?v=1788734961","url":"https:\/\/voomisupply.com\/products\/osg-3334319-screw-machine-drill-bit-4-3mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
