Built to ANSI standards as part of the M41CO series, it features a 135-degree split point with web thinning for reduced thrust and faster penetration on entry. The straight-cylindrical shank seats securely in standard drill chucks and quick-change holders. At 0.040 inches in diameter (Wire Size 60), this bit is designed for precision small-diameter work in metalworking, maintenance, and fabrication environments. Licensed machinists, tool and die workers, and maintenance technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling hard metals including stainless steel, high-nickel alloys, titanium, and hardened steels where high-performance tooling is required. The screw machine length format — shorter than a jobber-length bit — provides increased rigidity and reduced deflection, making it a strong choice for drill press, CNC, and manual machine applications where hole location accuracy matters. The 2.5xD flute-to-diameter ratio and tapered web configuration support chip evacuation in short, interrupted cuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt (M41 grade) construction for heat resistance and durability in hard material applications\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces walking and lowers required thrust force\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body increases rigidity and minimizes deflection versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular spiral promotes efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard chucks and quick-change systems\u003c\/li\u003e\n  \u003cli\u003eBuilt to ANSI specification for dimensional consistency across replacement purchases\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-performance OEM-style replacement for screw machine length cobalt drill bits in Wire Size 60 (0.040 inches) applications across metalworking, maintenance, and fabrication setups requiring M41-grade cobalt tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and maintenance technicians using standard drill chucks or quick-change tool holders rated for the shank diameter. Ensure the shank is fully seated and the chuck is tightened securely before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and manage heat buildup. Inspect the cutting edge before use and replace the bit if chipping or dullness is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0400 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M41\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Regular\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: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 2.5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: High Performance\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: M41CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5996169\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51723347099954,"sku":"5996169","price":56.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa2be07eba6984ccd5f161f94448d961_983df252-96e5-4729-a7cc-69cfc468dfcf.jpg?v=1788603647","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996169-cobalt-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
