Built from M2 high speed steel with a bright\/uncoated finish, it carries a 1.5-inch cutting diameter, a 6-inch length of cut, and a 1.25-inch Weldon flat shank. The four-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation and stable cutting. At 8.5 inches overall length, this is an extra-long configuration suited for deep-cavity and extended-reach operations where a standard-length end mill cannot reach. Licensed machinists and CNC operators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for milling steel, stainless steel, cast iron, and non-ferrous metals in both manual and CNC milling machine setups. The extra-long overall length makes it well suited for deep-pocket milling, tall workpiece profiles, and fixture-clearance situations in job shop and production machining environments. The Weldon flat shank provides positive drive in side-lock tool holders, reducing pullout risk during aggressive cuts in ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.5-inch cutting diameter with 6-inch length of cut for deep-reach applications\u003c\/li\u003e\n  \u003cli\u003eM2 high speed steel construction for general-purpose ferrous and non-ferrous milling\u003c\/li\u003e\n  \u003cli\u003eFour right-hand spiral flutes at 30-degree helix for balanced chip flow\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank prevents pullout in side-lock holders\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — compatible with a wide range of cutting fluids and oils\u003c\/li\u003e\n  \u003cli\u003eNot center-cutting — requires a pre-drilled or pre-bored entry point for plunge operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in milling machines accepting a 1.25-inch Weldon flat shank in side-lock or end mill holders.

Secure the Weldon flat shank in a properly sized side-lock holder and torque the set screw against the flat to prevent axial pullout — do not seat the screw on the flute relief. Power down and lock out the spindle before changing tooling. Because this end mill is not center-cutting, plunge entry into solid material is not recommended; use a pre-drilled hole or ramp entry instead.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 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: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel (M2)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eCenter Cutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 720-3620\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691978916146,"sku":"720-3620","price":195.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3646b9971ae16d64e313b128c89021d4.jpg?v=1788291684","url":"https:\/\/voomisupply.com\/products\/value-collection-720-3620-square-end-mill-1-1-2in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
