With a 7.5 mm diameter and a 140-degree R-thinned point, it delivers fast penetration and reduced thrust in hard and abrasive materials. The coated solid carbide construction provides heat and wear resistance beyond what high-speed steel can offer. At 94 mm overall length with a 38 mm flute length, this short-body geometry improves rigidity and reduces runout. Right-hand cut with a straight-cylindrical shank measuring 8 mm in diameter, it seats securely in standard drill chucks and collets. Rated for a 3xD flute-to-diameter ratio, it suits production drilling environments where precision and tool life matter.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in CNC machining centers, drill presses, and manual machines where short, rigid tooling is preferred. It is engineered for drilling steel, stainless steel, cast iron, titanium, and titanium alloys. Coolant-through capability supports through-spindle coolant delivery, making it well-suited for deep-hole applications in production settings. Machinists, toolroom technicians, and CNC operators working in metal fabrication, job shops, and manufacturing facilities will find this bit appropriate for precision hole-making in tough workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior wear resistance and rigidity in hard materials\u003c\/li\u003e\n\u003cli\u003e140-degree R-thinned point reduces thrust and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eCoated finish extends tool life when cutting steel, stainless steel, and titanium alloys\u003c\/li\u003e\n\u003cli\u003eCoolant-through design compatible with through-spindle coolant delivery systems\u003c\/li\u003e\n\u003cli\u003eScrew machine length body provides increased stiffness and reduced deflection\u003c\/li\u003e\n\u003cli\u003eTapered web with R-thinning minimizes chisel edge load at cut initiation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eOSG Series 5200 screw machine drill bit designed for use in workpiece materials including steel, stainless steel, cast iron, titanium, and titanium alloy. Fits any standard chuck or collet accepting an 8 mm straight-cylindrical shank. Drill bit size range for this series is 6.50 mm to 8.00 mm.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or CNC operators familiar with carbide tooling protocols. Secure the shank fully in the collet or chuck before operation and verify runout with a dial indicator when tolerance is critical. Carbide tooling is brittle and should not be used for interrupted cuts or hammer-action drilling. Always set appropriate spindle speed and feed rate for the workpiece material before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.5 mm (0.2953 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 94 mm (3.7008 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 38 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm (0.3150 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: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Titanium, Titanium Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.022 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.115 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: 8665750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748676436274,"sku":"8665750","price":241.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d20470e2b00faaeae1f71eaf9081275b_99c63111-a011-4b45-a10e-486343fdc0cf.jpg?v=1788896528","url":"https:\/\/voomisupply.com\/products\/osg-8665750-screw-machine-drill-bit-7-5-mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
