It accepts a 3\/4 inch Weldon flat shank with 2 flats for positive tool retention in compatible magnetic drill presses and rotary broaching equipment. The cutter diameter is 21\/32 inch (0.6562 inch decimal) with a 1 inch depth of cut. The bright, uncoated finish is standard for general-purpose HSS cutters operating at appropriate surface speeds with cutting fluid. Installation and use are handled by machinists, fabricators, and maintenance trades working with structural or plate steel.\u003c\/p\u003e\u003cp\u003eThis cutter is suited for production and maintenance applications where a clean-walled, burr-minimized through-hole is required in mild steel or structural steel plate. Annular cutters remove only a core of material rather than the full disc, reducing cutting force and heat compared to twist drills at equivalent diameters. The 1 inch depth of cut accommodates typical plate and structural section thicknesses encountered in fabrication and field work. The Weldon flat shank interface is the standard connection for magnetic drill press chucks and drill press arbors designed for annular tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e21\/32 inch (0.6562 inch) cutting diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e1 inch depth of cut handles common plate and structural section thicknesses\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides durability in mild and general steel applications\u003c\/li\u003e\n\u003cli\u003e3\/4 inch Weldon flat shank with 2 flats ensures positive drive and minimal slippage\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating interference when using cutting oil or coolant\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in magnetic drill presses and annular cutter arbors accepting a 3\/4 inch Weldon flat shank.

Always secure the magnetic base fully to the workpiece and confirm the cutter is fully seated and locked in the arbor before beginning a cut. Use cutting oil or appropriate metalworking fluid to extend tool life and manage heat. Power down and de-energize the drill completely before changing cutters or inspecting the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 21\/32 inch (0.6562 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Mild Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 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: HOUGEN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOUGEN","offers":[{"title":"Default Title","offer_id":51698899976498,"sku":"12121","price":54.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fad330c2864d8e6d0a2c36e62c914568.jpg?v=1788369608","url":"https:\/\/voomisupply.com\/products\/hougen-12121-annular-cutter-21-32-in-hss-weldon-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
