It features a 0.5-inch cutting diameter, a 0.625-inch length of cut, and a 2.5-inch overall length with a 0.5-inch shank diameter. The four-flute geometry with a 38-degree helix angle and spiral flute design promotes efficient chip evacuation and smooth cutting action. A TiAlCN finish increases surface hardness and thermal resistance, extending tool life in demanding cuts. The submicron grain carbide substrate provides toughness and wear resistance. This end mill is center-cutting, allowing direct plunge entry into the workpiece.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for general-purpose and high-efficiency milling in ferrous and non-ferrous metals, including steel, stainless steel, and cast iron, as well as harder alloys. It is intended for use in CNC machining centers and manual mills where consistent dimensional accuracy is required. The right-hand cut and right-hand flute configuration make it compatible with standard spindle setups. Variable index flute spacing helps reduce chatter and vibration during aggressive side milling or full-width slotting passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with submicron grain substrate for improved wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003eTiAlCN coating provides thermal and oxidation resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle with spiral flute geometry promotes efficient chip flow\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic vibration and chatter\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design enables direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard CNC and manual mill compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 0.5-inch shank square end mill for use in CNC machining centers, vertical mills, and toolholders accepting 0.5-inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the collet or end mill holder to the recommended gauge length and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the cutting edges 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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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 Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\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\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\u003ePackage Dimensions\u003c\/strong\u003e: 2.99 inches L x 0.75 inches W x 0.75 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 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: 3398299\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51749778489650,"sku":"3398299","price":84.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ba32a6c345bc1a81625bb9fb60cc37b_ac783cd0-a78a-48e3-9dbf-bfc81d17b2e9.jpg?v=1788910360","url":"https:\/\/voomisupply.com\/products\/iscar-3398299-square-end-mill-0-5-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
