Ground to a 3.5 mm diameter with a 140-degree split point, it delivers fast, self-centering entry without a center punch. The EgiAs coating reduces friction and extends tool life in abrasive workpiece materials. With an overall length of 74 mm and a 28 mm flute length, the bit fits standard drill chucks and machining centers. A tapered web with X-thinned point geometry keeps thrust forces low and chip evacuation clean. This bit is installed and used by machinists and tool-and-die professionals running precision drilling operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for blind hole drilling, cross hole drilling, through-hole drilling, and self-centering applications. Primary workpiece materials include steel, alloy steel, and cast iron. The 5xD flute-to-diameter ratio supports efficient chip removal in these materials. The straight-cylindrical shank accommodates standard collet chucks and drill chucks used in CNC machining centers, drill presses, and manual lathes in both production and job-shop environments.\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\u003e140-degree X-thinned point for self-centering entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eEgiAs coating for extended tool life and reduced friction\u003c\/li\u003e\n\u003cli\u003e2-flute spiral design with tapered web for reliable chip evacuation\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of plus 0 to minus 0.018 mm for close-tolerance hole sizing\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 4 mm shank fits standard collet and drill chuck tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length replacement drill bit for use in steel, alloy steel, and cast iron applications requiring a 3.5 mm hole diameter.

Ensure the spindle and workpiece are fully secured before initiating a cut. Use appropriate cutting fluid or coolant where the machine setup permits, and verify spindle speed and feed rate against published data for the workpiece material before running. Inspect the cutting edges for chipping or wear before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.5 mm (0.1378 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74 mm (approximately 2.91 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28 mm (approximately 1.10 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: X-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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003eCoating\u003c\/strong\u003e: EgiAs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\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\u003eTool Application\u003c\/strong\u003e: Blind Hole, Cross Hole, Drilling, Self-Centering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eSeries\u003c\/strong\u003e: 6310\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.026 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 8672350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733169996082,"sku":"8672350","price":115.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/172810fc138da7ef9b15339ce5eada04_445c7d7e-0b67-424e-a7ce-7e0460380f5c.jpg?v=1788752190","url":"https:\/\/voomisupply.com\/products\/osg-8672350-solid-carbide-jobber-drill-bit-3-5-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
