Built from M42 cobalt high-speed steel, it carries a Titanium Nitride (TiN) coating to extend tool life and reduce friction at the cutting edge. The 5\/16 inch diameter, four-flute configuration with a 30-degree helix angle delivers efficient chip evacuation on a variety of ferrous and non-ferrous materials. The square end profile suits flat-bottom slots and shoulder cuts. Right-hand flute direction and right-hand cutting rotation are standard. This tool is installed and operated by machinists and tool-and-die professionals in milling applications.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in manual knee mills, CNC vertical machining centers, and bridgeport-style machines where a single tool must handle both roughing and light finishing operations. The 3\/8 inch shank with Weldon flat provides positive drive and minimizes slippage in side-lock holders. The 1-1\/8 inch length of cut accommodates moderate-depth slot and peripheral milling. Single-end geometry means the tool is not reversible. Typical applications include slotting, profiling, and shoulder milling in steel, stainless, and similar alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank (3\/8 inch) ensures positive retention in side-lock holders\u003c\/li\u003e\n\u003cli\u003eFour-flute, square-end geometry handles both roughing and finishing passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute direction — compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or direct-use cobalt end mill for milling machines and machining centers accepting a 3\/8 inch Weldon flat shank in a side-lock or set-screw style end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's guidelines. Secure the Weldon flat shank fully into a properly sized side-lock holder, ensuring the flat registers against the set screw before tightening. Confirm spindle speed, feed rate, and depth of cut are within the recommended parameters for cobalt tooling before engaging the cut. Inspect the cutting edges before each use and remove the tool from service when chipping or excessive wear is observed.\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 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: Cobalt (M42 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/8 inches (1.125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-15\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Square\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\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 724-5056\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701223391538,"sku":"724-5056","price":98.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/59fa49ca07fde5f2d891db68beba534b.jpg?v=1788400164","url":"https:\/\/voomisupply.com\/products\/value-collection-724-5056-end-mill-5-16-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
