With a 0.5 inch cutting diameter, six spiral flutes, and a 45-degree helix angle, this tool delivers aggressive material removal with excellent chip evacuation. The submicron grain carbide substrate provides edge strength and wear resistance, while the AlTiN coating extends tool life in elevated-heat cutting conditions. At 3 inches OAL with a 1 inch length of cut, it is sized for standard reach milling applications. Centercutting geometry allows direct plunge entry. Installation and use are handled by machinists and CNC tooling professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling operations across a broad range of workpiece materials, including hardened steels, stainless steels, cast iron, non-ferrous alloys, and high-temperature alloys, consistent with its primary workpiece material codes H, K, M, P, and S. The straight cylindrical shank and 0.5 inch shank diameter make it compatible with standard ER collet chucks and end mill holders commonly found in vertical machining centers and CNC milling setups. Right-hand cut and right-hand flute configuration is the standard orientation for conventional and climb milling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSix spiral flutes with 45-degree helix angle for aggressive chip removal and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eSubmicron grain solid carbide substrate for superior edge retention and toughness\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for high-heat and abrasion resistance in ferrous and exotic alloy machining\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge milling without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute for standard milling spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard collet and end mill holder tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with workpiece material groups H, K, M, P, and S as specified by the manufacturer.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the straight shank fully into the collet or holder and torque the retention nut per the holder manufacturer's specifications. Verify tool runout with a dial indicator before beginning a cut, as runout directly affects tool life and surface finish with multi-flute carbide end mills.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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: 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: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H, K, M, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 5621958\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51750769787186,"sku":"5621958","price":205.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f2c725226bc1c67d28e87d1c53c7957.jpg?v=1788919545","url":"https:\/\/voomisupply.com\/products\/iscar-5621958-square-end-mill-6-flute-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
