Built from submicron-grade carbide and coated with TiAlN, it handles elevated cutting temperatures and maintains edge integrity across extended runs. The 6-flute configuration with a 45-degree spiral helix delivers efficient chip evacuation and smooth surface finishes. At 6 inches overall length with a 3.25-inch length of cut, this extra-long geometry reaches deep pockets and cavities that standard-length end mills cannot access. The 0.75-inch diameter matches the straight-cylindrical shank diameter for direct collet or end mill holder fitment.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for machining a broad range of workpiece materials including hardened steels, cast irons, stainless steels, carbon and alloy steels, and high-temperature superalloys, corresponding to material codes H, K, M, P, and S. It performs well in vertical machining centers, horizontal machining centers, and CNC milling machines where deep-reach finishing or semi-finishing passes are required. The centercutting design allows plunge entry, adding flexibility in complex toolpath strategies. It is typically deployed by machinists and CNC programmers in job shop, aerospace, die-mold, and general manufacturing settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron-grade solid carbide construction for wear resistance in difficult materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating provides thermal barrier and extends tool life at higher cutting speeds\u003c\/li\u003e\n\u003cli\u003e6 flutes with 45-degree spiral helix for high feed rates and reduced chatter\u003c\/li\u003e\n\u003cli\u003eExtra-long 3.25-inch length of cut for deep pocket and cavity applications\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry supports plunge milling and ramping operations\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute, straight-cylindrical shank for standard toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with workpiece material codes H, K, M, P, and S as specified by the manufacturer, covering hardened steels, cast irons, stainless steels, carbon and alloy steels, and superalloys.

Secure the shank fully into the holder to the recommended gauge-line depth before tightening to avoid runout. Verify spindle and toolholder cleanliness before assembly, as contamination affects runout and tool life. Do not exceed the toolholder manufacturer's rated clamping torque range, and confirm tool stick-out is minimized to the extent the application allows.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 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: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\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: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\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: 0.01 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: 5620988\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51752205779250,"sku":"5620988","price":899.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7175a3bc7a8a6c9fba27dfc136ee0352.jpg?v=1788926581","url":"https:\/\/voomisupply.com\/products\/iscar-5620988-square-end-mill-0-75in-6-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
