Built from micrograin solid carbide, it offers the rigidity and wear resistance needed for demanding cutting applications. The 3\/8 inch cutting diameter pairs with a 1 inch length of cut and a 4 inch overall length. A ZrN (zirconium nitride) coating reduces friction and extends tool life in dry or semi-dry machining environments. The 37-degree helix angle promotes efficient chip evacuation and reduces chatter. This end mill is installed and used by machinists and CNC operators in job shops, manufacturing facilities, and toolrooms.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling operations on CNC machining centers and manual mills. Its centercutting geometry allows plunge cutting directly into the workpiece. The right-hand cut and right-hand spiral flute configuration is standard for conventional and climb milling setups. The 3\/8 inch shank diameter fits standard ER collets and end mill holders commonly found in vertical machining centers. The single-end, three-flute design balances chip clearance with cutting edge support, making it effective on a range of workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n  \u003cli\u003eZrN coating reduces friction and improves wear resistance in dry machining\u003c\/li\u003e\n  \u003cli\u003e37-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute for standard CNC and manual mill setups\u003c\/li\u003e\n  \u003cli\u003eSpiral flute, three-flute configuration balances chip clearance with edge strength\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8 inch shank square end mill compatible with ER collet chucks, end mill holders, and other toolholding systems accepting a 3\/8 inch straight shank on CNC machining centers and manual vertical mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC operators. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully in the collet or holder and torque the retention nut to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates wear and reduces surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 95171742\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731423953202,"sku":"95171742","price":126.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64f9ffae5603e6fe6ff2b358b496d0a6.jpg?v=1788730896","url":"https:\/\/voomisupply.com\/products\/accupro-95171742-square-end-mill-3-8-in-3-flute-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
