Cobalt construction gives the bit greater heat resistance than standard high-speed steel, allowing it to maintain cutting edge integrity under high-friction conditions. The stub-length body provides added rigidity and reduced deflection compared to jobber-length bits, making it well suited for production drilling operations where accuracy and repeatability matter. Licensed machinists, tool-and-die technicians, pipefitters, and industrial maintenance mechanics are the primary users of this style of bit.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for use in drill presses, milling machines, and magnetic-base drills where a 1\/2-inch chuck is standard. The 29\/32-inch diameter is a common sizing for bolt clearance holes, port openings, and stepped-hole operations in steel, stainless steel, cast iron, and other ferrous materials. The reduced shank allows the bit to seat in standard 1\/2-inch chucks even though the cutting diameter exceeds that measurement, expanding its usability across common machine setups without the need for specialty tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction for improved heat resistance and extended tool life in hard metals\u003c\/li\u003e\n\u003cli\u003eStub screw machine length for increased rigidity and reduced bit deflection\u003c\/li\u003e\n\u003cli\u003e29\/32-inch cutting diameter suits bolt clearance and port-opening applications\u003c\/li\u003e\n\u003cli\u003e1\/2-inch reduced shank fits standard 1\/2-inch drill press and machine chucks\u003c\/li\u003e\n\u003cli\u003eSuitable for ferrous metals including steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine stub-length drill bit for use in drill presses, milling machines, and magnetic-base drills equipped with a standard 1\/2-inch chuck.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit should be installed by a qualified machinist or trained tradesperson familiar with rotary cutting tools. Secure the shank fully in the chuck and verify concentricity before drilling. Use appropriate cutting fluid or coolant when drilling ferrous metals to prolong tool life and maintain hole quality. Always wear eye protection and follow shop safety protocols when operating drilling equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 29\/32 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\u003eDrill Style\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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C1090-058-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51234006401330,"sku":"C1090-058-I","price":45.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620624.png?v=1780114761","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-c1090-058-i-cobalt-drill-bit-29-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
