Built from powdered metal and coated with titanium carbonitride (TiCN), this tool delivers improved wear resistance and surface hardness compared to standard high-speed steel. The 3\/4-inch diameter cutting face is paired with a 2-1\/4-inch length of cut and a 42-degree helix angle, which promotes efficient chip evacuation and reduced cutting forces. Three right-hand spiral flutes handle material removal across a broad range of metals and alloys. The tool is center-cutting, allowing plunge entry as well as conventional peripheral and slot milling.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for job shops, production machining, and tool rooms working with steel, stainless, cast iron, and similar ferrous materials. The TiCN coating extends tool life in abrasive and high-heat cutting conditions. The 3\/4-inch shank diameter fits standard collet chucks, end mill holders, and ER-style tooling commonly found on vertical and horizontal milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePowdered metal construction for improved toughness over standard HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and heat resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003e42-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge milling in addition to peripheral and slot operations\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker geometry for clean, continuous cuts in suitable materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 3\/4-inch collet chucks, end mill holders, and ER-style toolholders on vertical or horizontal milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before loading or removing the end mill. Insert the shank to the full recommended engagement depth in the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the cutting edges and coating for chips or damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.25 inches (2-1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches (4-1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 42 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0015 \/ -0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ED99921222\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728145940786,"sku":"ED99921222","price":170.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ff19e873692fdb101fd5c01c95c413a.jpg?v=1788688768","url":"https:\/\/voomisupply.com\/products\/accupro-ed99921222-square-end-mill-3-4-in-3-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
