With a cutter diameter of 1.5743 inches (approximately 40 mm) and a cutting depth of 50 mm (approximately 1.97 inches), this cutter removes only a small core of material rather than a full slug, reducing the power required and extending tool life. The Weldon flat shank with two flats accepts standard magnetic drill press chucks and provides positive rotational drive without slipping. The bright, uncoated finish is appropriate for general-purpose steel cutting applications. Licensed HVAC, plumbing, and electrical tradespeople as well as structural steel fabricators routinely use annular cutters for conduit knockout, pipe penetration, and structural connection work.\u003c\/p\u003e\u003cp\u003eThe 12440 is suited for drilling through mild steel and general steel plate using a magnetic drill press or compatible drill press equipped with a 3\/4-inch Weldon-style chuck. The 1.5743-inch diameter makes it a practical choice for conduit, pipe, and bolt-hole applications where a precise, burr-minimized hole is required. The cutter is packaged individually and sold as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.5743-inch (39.99 mm) cutter diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e50 mm cutting depth accommodates thicker plate and stacked material\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability in mild and general steel\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank with two flats prevents chuck slippage under load\u003c\/li\u003e\n\u003cli\u003e3\/4-inch shank diameter fits standard magnetic drill press Weldon chucks\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with cutting fluid on mild steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with magnetic drill presses and drill press equipment fitted with a 3\/4-inch Weldon flat shank chuck.

Ensure the magnetic drill base is fully engaged and the workpiece is clean and flat before energizing the magnet. Use an appropriate cutting fluid throughout the cut to reduce heat buildup and extend cutter life. Always de-energize the drill and allow the cutter to stop completely before removing it from the chuck or clearing chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 1.5743 inches (39.99 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 50 mm (approximately 1.97 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches\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: 0.56 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 12440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOUGEN","offers":[{"title":"Default Title","offer_id":51693758218546,"sku":"12440","price":180.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3dcaa3f0b458e7e584df96ac02c3a4ce.jpg?v=1788316995","url":"https:\/\/voomisupply.com\/products\/hougen-12440-annular-cutter-1-5743-in-hss-weldon-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
