Silver and Deming bits are engineered to drill oversized holes beyond the capacity of standard 3\/8 inch chuck drills. The 1\/2 inch shank allows the bit to seat in a standard 1\/2 inch drill chuck while delivering a larger cutting diameter. This bit is suited for metal fabrication, HVAC sheet metal work, plumbing rough-in, and general industrial drilling where large-diameter holes are required in steel, aluminum, or similar materials.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in residential and commercial trade applications where holes larger than standard jobber bits can produce are needed. Common scenarios include drilling through structural steel, angle iron, electrical enclosures, and sheet metal panels. Licensed trades including HVAC technicians, electricians, and plumbers reach for Silver and Deming bits when routing pipe or conduit through metal framing or when enlarging existing holes to final diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-9\/64 inch cutting diameter for oversized hole applications\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch reduced shank fits standard 1\/2 inch drill chucks\u003c\/li\u003e\n  \u003cli\u003eHigh Speed Steel construction resists heat buildup during metal drilling\u003c\/li\u003e\n  \u003cli\u003eSilver and Deming geometry delivers controlled chip evacuation in ferrous and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1 — available as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Silver and Deming replacement bit compatible with any 1\/2 inch keyed or keyless drill chuck.

Secure the 1\/2 inch shank firmly in the chuck before operation and confirm the chuck is fully tightened. Use cutting fluid or a suitable metal-cutting lubricant when drilling ferrous metals to extend bit life and reduce heat. Never force feed through hardened materials — reduce feed pressure and allow the flutes to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1-9\/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\u003eBit Type\u003c\/strong\u003e: Silver and Deming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 pounds\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: 1090-109-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51234022752562,"sku":"1090-109-I","price":38.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307619788.png?v=1780115336","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-1090-109-i-hss-silver-deming-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
