With a 1-15\/64 inch cutting diameter and a reduced 1\/2 inch shank, this bit fits standard 1\/2 inch drill chucks without requiring a dedicated large-capacity chuck. The slow spiral geometry helps control chip evacuation and reduces heat buildup when working through steel, cast iron, aluminum, and similar metals. This is a general-purpose production drill suited for machinists, maintenance technicians, and fabricators who need a reliable, repeatable large-diameter hole.\u003c\/p\u003e\n\u003cp\u003eThis bit is used in metalworking applications where a standard drill set falls short. Typical scenarios include enlarging existing holes, drilling mounting or clearance holes in structural steel, fabricating brackets, or working through thick-wall tubing. The 1\/2 inch reduced shank makes it compatible with commonly available drill presses, magnetic drills, and handheld 1\/2 inch chuck drills found in most shops and field kits. It is suited for both production floor and maintenance-and-repair environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-15\/64 inch cutting diameter for large-diameter hole work beyond standard drill set range\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction provides hardness and heat resistance for metal drilling\u003c\/li\u003e\n  \u003cli\u003eReduced 1\/2 inch shank fits standard 1\/2 inch drill chucks on drill presses and handheld drills\u003c\/li\u003e\n  \u003cli\u003eSlow spiral flute design promotes controlled chip removal and reduced heat buildup\u003c\/li\u003e\n  \u003cli\u003eSilver and Deming pattern for versatile use across steel, cast iron, aluminum, and similar materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit compatible with any drill press or power drill equipped with a standard 1\/2 inch chuck capacity.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and used by machinists, maintenance technicians, and metal fabricators. Secure the reduced shank firmly in a 1\/2 inch drill chuck before use and confirm the workpiece is clamped or fixtured to prevent rotation during drilling. Use cutting fluid or coolant appropriate for the workpiece material to extend bit life and improve hole quality. Inspect the cutting edges for wear before each use and avoid excessive feed pressure, which can cause premature tip failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1-15\/64 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\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Pattern\u003c\/strong\u003e: Silver and Deming Slow Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 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: 1090-115-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233875525938,"sku":"1090-115-I","price":44.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307619814.png?v=1780110981","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-1090-115-i-hss-silver-deming-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
