Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers the heat and wear resistance needed for tough ferrous and non-ferrous materials. The 0.5 inch diameter tool features 4 right-hand flutes with a coarse pitch designed to break up chips and reduce cutting forces. The 1.25 inch length of cut and 3.25 inch overall length suit standard vertical and horizontal milling machine setups. This tool is installed and operated by machinists and tool-and-die professionals in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for roughing passes on ferrous metals, stainless steels, and high-temperature alloys where a standard HSS end mill would overheat or wear prematurely. The coarse pitch flute geometry promotes chip evacuation and reduces chatter during deep cuts. Right-hand cutting and right-hand flute direction make it compatible with conventional CNC mills and manual knee mills running standard spindle rotation. It is not center-cutting and should not be used for direct plunge cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for elevated heat resistance and edge retention\u003c\/li\u003e\n\u003cli\u003eCoarse pitch, 4-flute design promotes aggressive chip breaking and evacuation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with cutting fluid and oil applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle setups\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 1.25 inch length of cut\u003c\/li\u003e\n\u003cli\u003eNot center-cutting — suited for peripheral and slot milling, not direct plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 0.5 inch shank roughing end mill suitable for use in collet chucks, end mill holders, and milling machine spindles accepting 0.5 inch shanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank fully into the holder and torque set screws or collet nuts per toolholder manufacturer specifications. Confirm proper cutter runout with a dial indicator before beginning a cut, and verify that cutting direction and spindle rotation match the tool geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt HSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eCenter Cutting\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: 0.25 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 723-5520\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712536052018,"sku":"723-5520","price":56.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa25b484d6233b9b071be2a1f5cbc6f6.jpg?v=1788486531","url":"https:\/\/voomisupply.com\/products\/value-collection-723-5520-roughing-end-mill-0-5in-cobalt-m42","provider":"Voomi Supply","version":"1.0","type":"link"}
