With a 2.5 mm cutting diameter and 4 flutes, it delivers clean, accurate cuts in ferrous and non-ferrous materials. The 43-degree helix angle promotes efficient chip evacuation and reduces cutting forces. A DUROREY coating extends tool life by increasing surface hardness and heat resistance. At 60 mm overall length with a 6 mm shank diameter and 6.3 mm length of cut, this end mill is engineered for tight-tolerance work on CNC machining centers and manual mills alike.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slot milling, peripheral milling, and profiling operations in production and job shop environments. The micrograin carbide substrate supports high cutting speeds and maintains edge integrity under demanding conditions. Right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations. It is a single-end tool, center-cutting, with no extended reach, making it a straightforward choice for general-purpose finish and semi-finish milling passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.5 mm cutting diameter with 6.3 mm length of cut for shallow-to-medium depth passes\u003c\/li\u003e\n\u003cli\u003e4-flute geometry for improved surface finish and material removal rate\u003c\/li\u003e\n\u003cli\u003e43-degree helix angle aids chip flow and lowers cutting pressure\u003c\/li\u003e\n\u003cli\u003eDUROREY coating for enhanced wear resistance and thermal stability\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction maintains sharp edges at high feeds\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry and ramping operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement solid carbide square end mill for CNC machining centers and manual mills accepting a 6 mm straight shank with right-hand spindle rotation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 6 mm shank fully into a collet or end mill holder and torque to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning a production run.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 2.5 mm (0.0984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 6.3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 60 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 43 degrees\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: DUROREY\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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle\/Double End\u003c\/strong\u003e: Single End\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.55 inches L x 0.45 inches W x 0.45 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8549725\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730494751026,"sku":"8549725","price":120.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46a3254f5acde6e640620cad36430345_8c0f04de-d25b-4788-8d23-94a654ec15d8.jpg?v=1788718441","url":"https:\/\/voomisupply.com\/products\/osg-8549725-square-end-mill-2-5mm-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
