Cobalt construction provides increased heat resistance and hardness compared to standard high-speed steel, making it well suited for drilling through tough ferrous metals, stainless steel, cast iron, and other hard-to-machine materials. The stub-length body reduces deflection and improves rigidity in short-reach drilling applications. Electricians, pipefitters, machinists, and maintenance technicians use this style of drill bit where accuracy and tool life in hard materials are priorities.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for use in stationary drill presses, magnetic drills, and heavy-duty hand drills equipped with a 1\/2-inch chuck. Typical applications include drilling clearance holes, pilot holes, and through-holes in structural steel, hard plate, and similar materials encountered in industrial and commercial trade work. The screw machine length profile makes it a practical choice in confined spaces or where a shorter bit is preferred for control and stability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e15\/16-inch cutting diameter for standard clearance and through-hole applications in hard materials\u003c\/li\u003e\n  \u003cli\u003eCobalt construction delivers superior heat and wear resistance over standard HSS bits\u003c\/li\u003e\n  \u003cli\u003eStub screw machine length reduces deflection and increases rigidity during drilling\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch straight shank fits standard 1\/2-inch drill chucks and magnetic drill arbors\u003c\/li\u003e\n  \u003cli\u003eSuited for ferrous metals, stainless steel, cast iron, and similarly hard workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for standard 15\/16-inch cobalt screw machine drill bits with a 1\/2-inch straight shank, compatible with any drill press, magnetic base drill, or heavy-duty hand drill accepting a 1\/2-inch shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist or qualified tradesperson should secure the bit fully in a 1\/2-inch chuck before operation. Ensure the workpiece is firmly clamped and the drill is powered down completely before bit changes. Use appropriate cutting fluid on hard or stainless materials to extend tool life and manage heat buildup. Follow applicable shop safety codes and wear appropriate PPE during all drilling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBit Type\u003c\/strong\u003e: Screw Machine (Stub) Length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.69 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\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: EAGLE CUTTING TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C1090-060-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233384988978,"sku":"C1090-060-I","price":45.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620622.png?v=1780098614","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-c1090-060-i-cobalt-drill-bit-15-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
