The set covers cutter diameters from 1\/2 inch through 1-1\/16 inch in 1\/16-inch increments, giving fabricators and ironworkers a continuous range for structural and sheet-metal work. Each cutter features a bright polished finish and is ground from cobalt high-speed steel, which holds an edge longer than standard HSS under the heat generated by magnetic drill press and rotary broach applications. The 5\/8-inch shank diameter is the industry-standard arbor size for most mag-drill platforms.\u003c\/p\u003e\n\u003cp\u003eThis set is used in fabrication shops, structural steel erection, HVAC ductwork framing, and mechanical piping layouts where clean, burr-minimal holes are required without pilot drilling. Annular cutters remove only the outer ring of material, reducing cutting force and heat compared to twist drills of equivalent diameter. The set is appropriate for electricians, pipefitters, ironworkers, and general fabricators working with mag drills or drill press setups equipped with a 5\/8-inch Weldon-style arbor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eCovers 10 cutter diameters: 1\/2, 9\/16, 5\/8, 11\/16, 3\/4, 13\/16, 7\/8, 15\/16, 1, and 1-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch cutting depth suitable for most structural steel and plate applications\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch shank diameter fits standard magnetic drill arbors\u003c\/li\u003e\n  \u003cli\u003eBright polished finish reduces friction and aids chip evacuation\u003c\/li\u003e\n  \u003cli\u003eIncludes 2 pilots for accurate cutter positioning and center location\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with magnetic drill presses and drill press setups equipped with a standard 5\/8-inch Weldon-style arbor.

Always secure the workpiece and verify the magnetic base has full, flat contact with the material before drilling. Insert the pilot pin before beginning each cut to prevent cutter walking on the workpiece surface. Disengage power and allow the cutter to come to a full stop before changing cutters or removing the pilot.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Cutter Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Cutter Diameter\u003c\/strong\u003e: 1-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright (Polished)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutters\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilots Included\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePiece Count\u003c\/strong\u003e: 11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.79 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: HOUGEN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOUGEN","offers":[{"title":"Default Title","offer_id":51694830420274,"sku":"17001","price":514.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/22b438216d7d778b7c897f36546a9550.jpg?v=1788328827","url":"https:\/\/voomisupply.com\/products\/hougen-17001-cobalt-annular-cutter-set-11-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
