It features a 3\/16 inch (0.1875 inch) mill diameter and a 1\/4 inch length of cut, with a matching 3\/16 inch shank diameter and a 2 inch overall length. The three-flute geometry, combined with a 45-degree helix angle and variable index spacing, reduces chatter and improves chip evacuation. A DLC (diamond-like carbon) coating adds surface hardness and lubricity, extending tool life in demanding cuts. The submicron carbide grade provides the edge retention and rigidity required for tight-tolerance work. This end mill is a single-end, center-cutting tool with right-hand cut and right-hand flute direction.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use on CNC machining centers and manual mills where small-diameter, high-precision slotting, profiling, or peripheral milling is required. The DLC coating makes it particularly effective in non-ferrous materials, composites, and graphite, where lubricity and edge sharpness are critical. The compact 2 inch overall length and short 1\/4 inch length of cut make it well matched to close-clearance work and shallow-depth finishing passes. Machinists working in aerospace, medical device, and general precision manufacturing will find this geometry appropriate for fine-feature work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/16 inch diameter with 1\/4 inch length of cut for small-feature precision milling\u003c\/li\u003e\n\u003cli\u003eDLC coating improves hardness, lubricity, and edge life compared to uncoated carbide\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes smooth cutting action and efficient chip removal\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic vibration and chatter\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry as well as peripheral and slot milling\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide grade delivers consistent edge integrity at elevated cutting speeds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 3\/16 inch straight shank end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. The shank should be secured in a collet or end mill holder rated for the shank diameter before spindle engagement. Verify runout with a dial indicator after tooling setup to protect edge integrity on fine-tolerance cuts. Follow shop-standard speeds and feeds for the workpiece material and coating type; do not exceed the tool manufacturer's recommended depth-of-cut limits for this diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/4 inches (0.25 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\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: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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 Index\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: DLC (Diamond-Like Carbon)\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: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3399006\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51730654167346,"sku":"3399006","price":62.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f4db0e48a1997cfe5dd176c66a02da0_23302e28-783c-495d-aa5f-69fdcffc0b5c.jpg?v=1788720929","url":"https:\/\/voomisupply.com\/products\/iscar-3399006-square-end-mill-3-16-in-3-flute-dlc-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
