The bit measures 4.3 mm in diameter with an overall length of 68 mm and a flute length of 28 mm. It features a 120-degree drill point angle with an R+W-thinned web for improved self-centering and reduced thrust force at entry. The WD1 coating provides enhanced wear resistance and tool life in demanding production environments. This bit is sized at a 5xD flute-to-diameter ratio and carries a straight-cylindrical shank with a shank diameter of 5.0 mm. It is intended for use by machinists, tool-and-die technicians, and maintenance professionals working with ferrous stock.\u003c\/p\u003e\u003cp\u003eThe OSG 3318430 is suited for drilling blind holes, cross holes, and through holes in steel workpieces where accuracy and tool longevity are priorities. Its slow spiral flute geometry and tapered web configuration make it appropriate for short-chip materials. The 120-degree point angle and thinned web support self-centering entry, reducing the need for a pilot hole in many applications. This bit is a fit for CNC machining centers, drill presses, and manual machines operating with right-hand spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in steel cutting\u003c\/li\u003e\n\u003cli\u003eWD1 coating for extended tool life and reduced wear\u003c\/li\u003e\n\u003cli\u003e120-degree drill point angle with R+W-thinned web for self-centering entry\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute geometry optimized for short-chip ferrous materials\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 5.0 mm diameter for broad machine compatibility\u003c\/li\u003e\n\u003cli\u003eRated for blind hole, cross hole, drilling, and self-centering applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide jobber drill bit for right-hand spindle machines accepting a straight-cylindrical shank; compatible with steel and other primary workpiece materials coded H per OSG Series 5171 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with carbide tooling. Secure the shank fully in the drill chuck or collet before operation and verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before engaging the cut. Solid carbide tooling is brittle and should not be used in machines with excessive runout or play. Do not use this bit for left-hand spindle rotation; it is designed for right-hand cutting only.\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 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 68 mm (2.677 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28 mm (1.102 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5.0 mm (0.197 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Slow\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: R+W-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: WD1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\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: 5171\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 3318430\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51735701750066,"sku":"3318430","price":190.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/33f74288be2c227e07c778bafc8d84e0.jpg?v=1788773687","url":"https:\/\/voomisupply.com\/products\/osg-3318430-solid-carbide-jobber-drill-bit-4-3-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
