Designed for milling slots, pockets, and profiles in ferrous and non-ferrous materials, it features a 5\/16-inch cutting diameter and a 3\/4-inch length of cut. The 30-degree right-hand spiral helix promotes efficient chip evacuation and smooth cutting action. The bright\/uncoated finish is standard for general-purpose HSS tooling. This end mill is sized for use in manual mills, CNC machining centers, and drill press setups where a 3\/8-inch shank is required. Machinists and tool-and-die professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for general-purpose face milling, side milling, and slotting operations in shops handling light to medium stock removal. The 3\/8-inch shank diameter fits standard collets and end mill holders commonly found in both manual Bridgeport-style mills and smaller CNC vertical machining centers. The 2-1\/2-inch overall length keeps the tool rigid in typical setups. It is not center-cutting, so it is not intended for direct plunge operations without a pre-drilled pilot hole or ramping entry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-inch cutting diameter with 3\/4-inch length of cut for slotting and profiling\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration for improved surface finish on ferrous materials\u003c\/li\u003e\n  \u003cli\u003eM2 high speed steel construction for durability in general-purpose machining\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand helix promotes chip clearance and reduces cutting force\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids on a wide range of materials\u003c\/li\u003e\n  \u003cli\u003eNon-center-cutting design — requires ramping or pre-drilled entry for plunge moves\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stock end mill for setups requiring a 3\/8-inch shank, 5\/16-inch diameter, 4-flute HSS square end mill with a 3\/4-inch length of cut.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist with the machine powered down and the spindle fully stopped before tool changes. Seat the 3\/8-inch shank fully in the collet or end mill holder and torque the retention hardware to the machine manufacturer's specification. Confirm runout with a dial indicator before beginning a cut. Because this tool is not center-cutting, program a ramp or helical entry when milling closed pockets.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inches (0.75 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 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\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: 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\u003eCenter Cutting\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\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 27603\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691569807666,"sku":"27603","price":25.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/238e6b2fd54d3d2abb1ab7d46aa69488.jpg?v=1788287116","url":"https:\/\/voomisupply.com\/products\/value-collection-27603-square-end-mill-5-16-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
