It features a 5\/8 inch (0.625 inch) mill diameter, a 1-7\/8 inch (1.875 inch) length of cut, and a 5 inch overall length. The three-flute configuration combined with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. A DLC (Diamond-Like Carbon) coating reduces friction and extends tool life in demanding applications. Micrograin carbide construction provides edge hardness and wear resistance. This end mill is a single-end, right-hand cutting and right-hand flute tool with centercutting capability, making it suitable for plunge and slot operations.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual milling machines for slotting, profiling, and peripheral milling operations. The 5\/8 inch shank diameter matches standard collet and toolholder sizes common in job shops, production machining, and toolroom environments. The DLC coating makes it well-suited for non-ferrous metals, composites, and abrasive materials where heat and friction management are priorities. Machinists and CNC operators working on close-tolerance part features will find the micrograin carbide grade appropriate for finishing and semi-finishing passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8 inch mill diameter with matching 5\/8 inch shank diameter for concentric fitment in standard holders\u003c\/li\u003e\n\u003cli\u003e1-7\/8 inch length of cut for deep slot and profile work\u003c\/li\u003e\n\u003cli\u003e3-flute geometry balances chip removal with core strength\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth cutting action and efficient chip flow\u003c\/li\u003e\n\u003cli\u003eDLC coating reduces friction and improves tool life in abrasive and non-ferrous applications\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction delivers consistent edge integrity and dimensional stability\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 5\/8 inch collet chucks, end mill holders, and toolholders on CNC machining centers and conventional milling machines.

Ensure the spindle is fully powered down and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the holder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning any cut to protect the tool and workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.625 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-7\/8 inch (1.875 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.625 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: DLC (Diamond-Like Carbon)\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\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: 5.15 inches L x 0.9 inches W x 1 inch H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.63 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 86301309\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727748792626,"sku":"86301309","price":273.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/322fbfd5a2320cf18d0879c8cc2aed35.jpg?v=1788681661","url":"https:\/\/voomisupply.com\/products\/osg-86301309-square-end-mill-5-8-in-3-flute-solid-carbide-dlc","provider":"Voomi Supply","version":"1.0","type":"link"}
