With a 5\/8-inch cutting diameter and 1-inch depth of cut, it removes only the outer ring of material rather than a solid slug, reducing heat buildup and extending tool life compared to twist drills. The cutter uses an M2 grade high speed steel body with a titanium nitride (TiN) coating to improve surface hardness and wear resistance. It is installed by machinists, ironworkers, and fabricators using magnetic drill presses or rotary broaching setups that accept a Weldon flat shank.\u003c\/p\u003e\u003cp\u003eThis cutter is suited for production and field applications involving mild steel, stainless steel, and general steel stock. The 3\/4-inch Weldon flat shank with two flats provides positive engagement in compatible drill press chucks and eliminates slippage under torque. Typical use cases include structural steel fabrication, pipe fitting layout, and on-site steel erection where a magnetic drill is used to produce clean, burr-minimal holes without pre-drilling a pilot.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-inch cutting diameter with 1-inch depth of cut for through-hole work in standard structural steel\u003c\/li\u003e\n\u003cli\u003eM2 high speed steel construction for toughness and heat resistance\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e3\/4-inch Weldon flat shank with 2 flats for secure, slip-free chuck engagement\u003c\/li\u003e\n\u003cli\u003eAnnular cutting geometry removes only the outer ring, lowering cutting force and heat\u003c\/li\u003e\n\u003cli\u003eRated for mild steel, stainless steel, and general steel applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with magnetic drill presses and drill press chucks that accept a 3\/4-inch Weldon flat shank connection.

Secure the cutter fully into the chuck, confirming both Weldon flats are engaged before applying power. Use cutting oil or appropriate metalworking lubricant continuously during the cut to control heat and extend tool life. Inspect the cutting edges before each use and retire the cutter if chipping or excessive wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\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 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\u003eCutter Material\u003c\/strong\u003e: M2 High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Mild Steel, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 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: 12620\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOUGEN","offers":[{"title":"Default Title","offer_id":51692946915634,"sku":"12620","price":64.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/467764bad2d984e021bc845fc615736f.jpg?v=1788305301","url":"https:\/\/voomisupply.com\/products\/hougen-12620-annular-cutter-5-8-in-hss-tin-weldon-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
