Built from solid carbide with a coated finish, this bit measures 0.274 inches (6.96 mm) in diameter and carries a 140-degree drill point angle for aggressive, accurate entry. The slow-spiral flute geometry and R-thinned, tapered web reduce thrust load and improve chip evacuation in tough materials. Coolant-through capability makes it suitable for production environments where heat management is critical. It is intended for use by machinists, tool-and-die professionals, and industrial maintenance techs working with difficult-to-machine alloys.\u003c\/p\u003e\n\u003cp\u003eThis drill bit fits applications in precision machining, aerospace component work, and industrial maintenance where short, rigid tooling is preferred. The screw machine length format provides greater rigidity compared to jobber-length bits, making it well suited for CNC machining centers, drill presses, and manual mills where chatter and deflection must be minimized. The 3xD flute-to-diameter ratio supports effective chip clearing in short-hole drilling operations on alloy steel and nickel alloy substrates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for durability in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle for fast, centered engagement\u003c\/li\u003e\n  \u003cli\u003eSlow-spiral flute design optimized for nickel alloys and alloy steels\u003c\/li\u003e\n  \u003cli\u003eR-thinned, tapered web reduces cutting thrust and improves bit life\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed production drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-performance replacement-style screw machine drill bit for use with alloy steel and nickel alloy workpieces; fits standard straight-shank drill chucks and collets accepting an 8.00 mm (0.315 inch) shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with carbide tooling. Ensure the spindle and workholding are powered down and secured before changing tooling. Carbide bits are brittle and should not be dropped or over-torqued in the chuck. Verify coolant flow is active before engaging the cut when using the through-coolant feature.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.274 inches (6.96 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 83.00 mm (approximately 3.27 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 35.00 mm (approximately 1.38 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Slow\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\u003ePoint Type\u003c\/strong\u003e: Standard\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\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Nickel Alloy\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 -0.022 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5950Ni\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.8 x 0.4 x 0.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.125 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: 595027411\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737993085234,"sku":"595027411","price":191.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32e50eec033da25f44a4a44c8709c900.jpg?v=1788795510","url":"https:\/\/voomisupply.com\/products\/osg-595027411-screw-machine-drill-bit-0-274-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
