Built from solid carbide with a coated finish, this bit delivers superior wear resistance and heat management compared to high-speed steel alternatives. The 140-degree split point reduces walking and thrust load at entry, while the R-thinned web improves chip evacuation and cutting efficiency. At 3.150 inches overall length and 0.1875 inches (3\/16 inch) diameter, it fits standard stub-length drilling setups. Coolant-through capability makes it compatible with CNC machining centers running high-pressure coolant systems. Licensed machinists and tooling professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for production and precision drilling in ferrous and non-ferrous metals including steel, alloy steel, cast iron, titanium, and titanium alloys. The screw machine (stub) length format provides added rigidity over jobber-length bits, reducing deflection in tight setups or when drilling on CNC lathes, machining centers, and drill presses. The 3xD flute-to-diameter ratio and regular spiral type make it appropriate for through-hole and blind-hole work in medium to hard workpiece materials. It is sold individually as a single-piece unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle reduces entry thrust and minimizes walking\u003c\/li\u003e\n  \u003cli\u003eR-thinned web with tapered web configuration improves chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design compatible with high-pressure internal coolant systems\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 2-flute spiral configuration in OSG Series 6500\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, alloy steel, cast iron, titanium, and titanium alloy workpieces. Compatible with CNC machining centers, CNC lathes, and drill presses equipped with straight-shank toolholders or collets sized for a 0.1875-inch diameter shank. Coolant-through use requires a machine spindle with internal coolant delivery.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed with the machine in a fully powered-down, locked-out state per applicable OSHA lockout\/tagout procedures. Seat the straight shank fully and evenly in the collet or chuck before tightening to manufacturer-specified clamping torque for the holder type in use. When using coolant-through capability, verify that the coolant pressure and flow rate are within the limits recommended for the toolholder. Inspect the cutting edges and coating condition before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch, 4.76 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.150 inches (80.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.142 inches (29.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eSeries\u003c\/strong\u003e: 6500\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 650018711\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753165357362,"sku":"650018711","price":155.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04ec6577c1375b9f397467d272bfb5cc.jpg?v=1788933427","url":"https:\/\/voomisupply.com\/products\/osg-650018711-screw-machine-drill-bit-3-16-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
