It features a 5\/16 inch (0.3125 inch) cutting diameter, a 1-3\/4 inch (1.7500 inch) length of cut, and 4 helical flutes with a 38\/41 variable helix geometry. The AlCrN coating provides enhanced heat resistance and tool life in demanding cutting environments. Manufactured from micrograin solid carbide, this single-end mill is suited for high-feed roughing and finishing passes. It is centercutting capable, allowing plunge entry into the workpiece. Machinists and toolroom professionals specify this end mill for ferrous and hardened material applications where coating performance and edge retention are critical.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual milling machines where close-tolerance slot milling, peripheral milling, and contouring are required. The 5\/16 inch shank diameter matches the cutting diameter, making it compatible with standard collets and toolholders of that bore size. The right-hand cutting and right-hand flute direction are standard for conventional and climb milling setups. The variable helix angle reduces harmonic vibration and chatter during cut, improving surface finish and tool stability in both roughing and semi-finishing operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlCrN coating for elevated heat and oxidation resistance in high-speed cuts\u003c\/li\u003e\n\u003cli\u003e38\/41 variable helix reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003e4 helical flutes provide efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with right-hand cut and right-hand flute direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 5\/16 inch bore collets and toolholders in CNC machining centers and manual knee mills.

Ensure the spindle is fully stopped and the machine is powered down before loading or removing the end mill from the collet or toolholder. Use a properly sized collet or end mill holder to achieve the correct clamping grip length and minimize runout. Follow machine tool manufacturer torque specifications when tightening the drawbar or collet nut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 5\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.3125 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-3\/4 inch (1.7500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlCrN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: 38\/41 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\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 Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: M.A. FORD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 277XCB3120B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51728148332850,"sku":"277XCB3120B","price":182.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/743a79de9bbfc7a5e3ff2d6c9cbcc7d1.jpg?v=1788688799","url":"https:\/\/voomisupply.com\/products\/m-a-ford-277xcb3120b-square-end-mill-5-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
