At 0.12 inches in diameter with a 135-degree split point, it starts on contact without walking and reduces the thrust needed to penetrate tough workpieces. The M41CO cobalt construction handles the heat generated by hard material drilling and maintains cutting edge integrity under sustained use. At 1.875 inches overall length with a 0.875-inch flute, this stub-length bit provides added rigidity, making it well suited for applications where deflection and chatter must be minimized.\u003c\/p\u003e\u003cp\u003eThis bit is intended for use in screw machine operations, CNC machining centers, drill presses, and hand-held power drills where a short, stiff tool is preferred. The straight-cylindrical shank fits standard drill chucks without an adapter. It is built for right-hand cut operation and handles hard ferrous and non-ferrous metals, hardened alloys, stainless steel, and similarly tough workpiece materials. The regular spiral and tapered web configuration promote chip evacuation at the 2.5xD flute-to-diameter ratio.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM41 cobalt tool steel construction withstands high cutting temperatures in hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point starts on contact and reduces walking on curved or hard surfaces\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 1.875 inches overall provides maximum rigidity and minimized deflection\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web design lowers thrust requirements and improves chip flow\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks directly, no adapter required\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards; rated for heavy-duty, high-performance drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-use cobalt stub drill bit for use in screw machine operations and machining setups requiring a 0.12-inch diameter, straight-shank drill bit in the M41CO series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this bit is performed by machinists and tool and die tradespeople. Secure the straight-cylindrical shank firmly in a keyed or keyless drill chuck before operation. Coolant-through operation is not supported on this bit; use appropriate cutting fluid applied externally when drilling hard materials to manage heat buildup. Inspect the cutting edges for wear before each use and replace bits that show chipping or dulling to prevent workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.12 inches (Wire Size: #31)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.875 inches\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\u003eTool Material\u003c\/strong\u003e: Cobalt (M41 Grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M41CO\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\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 by 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\u003ePerformance Rating\u003c\/strong\u003e: High Performance, Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 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: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5996045\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51689027469618,"sku":"5996045","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa2be07eba6984ccd5f161f94448d961.jpg?v=1788254041","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996045-cobalt-drill-bit-0-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
