Measuring 5.5 mm in cutting diameter with a 16 mm length of cut, this 4-flute tool delivers consistent chip evacuation and surface finish across a wide range of workpiece materials. The TiAlN coating extends tool life by resisting heat buildup at elevated cutting speeds. With a 50 mm overall length and a matching 5.5 mm straight-cylindrical shank, it mounts directly into standard collet chucks and end mill holders. The 30-degree helix angle supports smooth, chatter-resistant cuts. Machining centers, CNC mills, and manual knee mills in job shop and production environments are the primary platforms for this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling operations on hardened steels, cast irons, stainless steels, carbon and alloy steels, and high-temperature alloys, corresponding to material groups H, K, M, P, and S. It is a single-end, center-cutting tool, meaning it can be used for plunge entry as well as peripheral and slot milling. Regular-length classification makes it appropriate for general-purpose pocketing, contouring, and profile work where extended reach is not required. It weighs approximately 0.037 pounds, making it a compact tool suited for small-feature machining.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5.5 mm cutting diameter with mill diameter tolerance of -0.020 to 0.038 mm for close-tolerance work\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating provides heat resistance and extended tool life in ferrous and high-temp alloy cutting\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral geometry with 30-degree right-hand helix for smooth chip flow and reduced vibration\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry without a pre-drilled starting hole\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction in material grade IC900 for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard ER collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide end mill for use in CNC machining centers and manual milling machines equipped with standard collet or end mill holder systems accepting a 5.5 mm straight shank.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the end mill from its holder. Seat the shank to the full recommended engagement depth in the collet or holder, and verify runout with a dial indicator before beginning a cut. Consult applicable shop safety standards and machine tool guidelines for proper RPM, feed, and depth-of-cut parameters based on the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5.5 mm (0.2165 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 16 mm (0.6299 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5.5 mm (0.2165 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: 0.000 \/ -0.008 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.020 to 0.038 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: IC900\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Workpiece Material Groups\u003c\/strong\u003e: H, K, M, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.037 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.32 inches length x 0.47 inches width x 0.47 inches height\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5651190\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51733605876018,"sku":"5651190","price":65.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a3ef65c889f5ef3a9e3c7c5e5284039.jpg?v=1788756807","url":"https:\/\/voomisupply.com\/products\/iscar-5651190-square-end-mill-5-5mm-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
