Manufactured from M2 high speed steel with a bright uncoated finish, it offers reliable performance in ferrous and non-ferrous materials without the added cost of a coated tool. The cutting diameter is 0.3125 inches (5\/16 inches), with a length of cut of 0.75 inches, a 3\/8-inch shank diameter, and a 3.5-inch overall length. The 30-degree helix angle promotes efficient chip evacuation, and the centercutting geometry allows for direct plunge entry. Both ends are usable, extending tool life between changes.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits light to medium-duty milling, slotting, profiling, and peripheral cutting on manual mills and CNC machining centers. The double-end configuration makes it a practical choice for production shops and tool cribs looking to stretch tooling budgets. The right-hand cut and right-hand spiral flute configuration is standard for conventional milling setups. It is sold individually and is appropriate for job shops, maintenance machining, and prototype work where M2 HSS tooling meets the material and speed requirements of the application.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design provides two usable cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003eM2 high speed steel construction — suitable for steel, aluminum, brass, and plastics\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — compatible with most cutting fluids and oils\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute — standard orientation for conventional milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/8-inch end mill holders, collets, and milling chucks on vertical mills, knee mills, and CNC machining centers.

Secure the 3\/8-inch shank fully into a matched collet or end mill holder and tighten to the machine manufacturer's specified torque before cutting. Confirm spindle direction is set to right-hand rotation before engaging the cut. Inspect both cutting ends for chipping or wear before each use, and never exceed the material and speed ratings appropriate for M2 HSS tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches (3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel (M2)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\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\u003eSeries\u003c\/strong\u003e: VCCCDE-HSS-4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 720-4108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693334069554,"sku":"720-4108","price":53.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cbf2430c065266439035d7745ac9bf35.jpg?v=1788310802","url":"https:\/\/voomisupply.com\/products\/value-collection-720-4108-square-end-mill-5-16-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
