It features a 5\/16 inch (0.3125 inch) mill diameter, a 1-1\/8 inch length of cut, and a 2-1\/2 inch overall length. The three-flute, helical design with a 36-degree helix angle promotes efficient chip evacuation and smooth cutting performance. This is a centercutting tool, allowing plunge entry directly into the workpiece. The uncoated carbide construction suits applications where coating is not required or where the substrate alone meets the demands of the material being machined.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling non-ferrous metals such as aluminum, brass, and copper in both manual and CNC machining centers. Its straight cylindrical shank with h6 tolerance fits standard collets and tool holders used in precision machining environments. The Series 138 designation places it within M.A. FORD's line of general-purpose solid carbide end mills. It is typically installed by machinists and tool-and-die professionals working in job shops, production facilities, and maintenance machining applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in non-ferrous metal cutting\u003c\/li\u003e\n\u003cli\u003eThree helical flutes with 36-degree helix angle for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without pre-drilled entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration for standard spindle operation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with h6 tolerance for accurate tool holder fitment\u003c\/li\u003e\n\u003cli\u003eUncoated substrate suited for non-ferrous and other compatible workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide end mill for use in standard collet chucks and end mill holders accepting a 5\/16 inch straight-cylindrical shank.

Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Confirm runout with a dial indicator after clamping to minimize tool deflection and premature wear. Follow the machine tool manufacturer and applicable OSHA guidelines for speeds, feeds, and personal protective equipment when operating end mills.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/8 inches (1.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003eVariable Helix\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\u003eChipbreaker\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 138\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 13831255\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51748517052722,"sku":"13831255","price":87.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f857fc6fa96f6209f77d67bdd9e438b4_13fae0cc-3071-4bac-a357-cdc30684dec9.jpg?v=1788894732","url":"https:\/\/voomisupply.com\/products\/m-a-ford-13831255-square-end-mill-5-16-inch-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
