Unlike twist drills, an annular cutter removes only a core of material at the perimeter of the hole, reducing heat buildup and extending tool life. The cutter measures 0.8268 inches in diameter and reaches a cutting depth of approximately 1.969 inches (50 mm). The 3\/4-inch Weldon flat shank with two flats provides a positive, slip-resistant connection in compatible magnetic drill press chucks. The bright, uncoated finish is standard for high speed steel tooling in light to medium-duty applications.\u003c\/p\u003e\n\u003cp\u003eThis cutter is suited for steel fabrication, structural work, and maintenance applications where accurately sized holes are required in mild or low-carbon steel. It is a common choice for ironworkers, pipefitters, fabricators, and maintenance mechanics using magnetic base drills or drill press setups equipped with a Weldon-style chuck. Typical use cases include punching clean holes in plate steel, angle iron, tube steel, and structural channel without the need for a pilot hole in many setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.8268-inch (21 mm) cutting diameter for precise, consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles mild steel and general steel stock\u003c\/li\u003e\n  \u003cli\u003eCutting depth of 1.969 inches (50 mm) accommodates thick plate and structural sections\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch Weldon flat shank with 2 flats locks securely in Weldon-compatible chucks\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no coating to chip or peel under heavy use\u003c\/li\u003e\n  \u003cli\u003eAnnular cutting geometry removes less material than a twist drill, reducing cycle time and heat\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with magnetic base drills and drill presses equipped with a 3\/4-inch Weldon flat shank chuck.

Before mounting the cutter, ensure the drill is powered off and the chuck is fully secured around both Weldon flats to prevent rotation under load. Use cutting fluid or a cutting oil appropriate for high speed steel tooling on steel stock to manage heat and extend cutter life. Always secure the workpiece before engaging the magnetic base and beginning the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.8268 inches (21 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 1.969 inches (50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (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: 0.28 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: 12421\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOUGEN","offers":[{"title":"Default Title","offer_id":51694134067506,"sku":"12421","price":80.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4752ca333bb0c03aede4351a71f208c1.jpg?v=1788320725","url":"https:\/\/voomisupply.com\/products\/hougen-12421-annular-cutter-0-8268-in-hss-weldon","provider":"Voomi Supply","version":"1.0","type":"link"}
