It carries a 0.0785 inch diameter corresponding to #47 wire gauge sizing, a 135-degree split point for fast penetration and reduced walking, and a web-thinned, tapered-web construction that lowers thrust requirements on tough stock. The straight-cylindrical shank seats securely in standard drill chucks. At 1-11\/16 inches overall length with an 11\/16 inch flute, the stub-length body provides rigidity suited to close-tolerance screw machine and CNC operations. Licensed machinists, tool-and-die workers, and production floor operators are the typical users.\u003c\/p\u003e\n\u003cp\u003eThis bit is applied in screw machine operations, CNC drilling centers, and manual drill press work where short, rigid tooling is required to maintain hole accuracy in hard or abrasive workpiece materials. The M41CO series cobalt alloy construction retains hardness at elevated cutting temperatures, making it appropriate for stainless steel, hardened alloys, cast iron, and similarly demanding materials. The right-hand spiral flute clears chips efficiently during through-hole and blind-hole drilling. This is a single-piece package sold in multiples of 12 per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt (M41 grade) tool material retains cutting hardness at high temperatures for demanding workpiece materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and minimizes drill walking on hard surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered-web design lowers cutting resistance and extends bit life\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length body provides superior rigidity for tight-tolerance drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard 3-jaw and collet-style drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eANSI-standard geometry ensures dimensional consistency across production runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production consumable for screw machine and CNC drilling operations requiring a #47 wire gauge cobalt stub-length drill bit with a straight-cylindrical shank conforming to ANSI standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and machine operators. Secure the shank fully in the chuck or collet and verify runout before commencing a cut. Power down and de-energize the machine spindle completely before changing tooling. Do not exceed the recommended surface footage for cobalt tooling in the material being drilled, and apply cutting fluid appropriate to the workpiece material to maximize tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: #47\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0785 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M41 grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 2.5xD\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 Material\u003c\/strong\u003e: Hard Material\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\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 piece (minimum order quantity: 12)\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: 5996109\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51701580693810,"sku":"5996109","price":48.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa2be07eba6984ccd5f161f94448d961_c34ad8e2-b875-47b1-b095-0eab7455f31f.jpg?v=1788401949","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996109-cobalt-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
