It features a 3\/8 inch diameter, a 1\/2 inch length of cut, and a 5-flute solid carbide construction with a TiAlCN coating. The 38-degree helix angle and variable index flute spacing work together to reduce chatter and improve surface finish. At 2 inches overall length with a 3\/8 inch shank diameter, this tool fits standard collet and end mill holders used in CNC machining centers and manual mills. It is centercutting and runs right-hand cutting and flute directions.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for high-speed finishing and semi-finishing passes in steel, stainless, cast iron, and similar materials. The submicron carbide grade provides edge retention under demanding cutting conditions. It is a single-end tool, making it appropriate for operations where tool life and edge integrity are critical. Machinists and CNC operators in job shops, production facilities, and tool rooms are the primary users of this type of cutter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-flute design increases feed rates and improves surface finish compared to standard 4-flute tools\u003c\/li\u003e\n\u003cli\u003eTiAlCN coating improves heat resistance and extends tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle reduces cutting forces and chatter\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing further dampens vibration during high-speed cuts\u003c\/li\u003e\n\u003cli\u003eCentercutting capable, allowing plunge entry\u003c\/li\u003e\n\u003cli\u003eSubmicron solid carbide grade for consistent edge sharpness and toughness\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/8 inch collets, ER collet chucks, and end mill holders on CNC machining centers and manual knee mills.

Ensure the spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank to the full recommended engagement depth in the holder and torque the retention mechanism per the holder manufacturer specifications. Inspect the cutting edges and coating condition before each use and replace the tool if chipping or coating loss is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlCN\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3398527\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51737005359410,"sku":"3398527","price":80.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ba32a6c345bc1a81625bb9fb60cc37b_60a13340-254a-400b-8925-c033eee4251c.jpg?v=1788783068","url":"https:\/\/voomisupply.com\/products\/iscar-3398527-square-end-mill-3-8-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
