With a 4 mm cutting diameter, 3-flute configuration, and a 37-degree helix angle, this end mill delivers efficient chip evacuation and smooth cutting action. The zirconium nitride (ZrN) coating reduces friction and extends tool life in demanding machining applications. The micrograin carbide substrate provides the hardness and edge retention needed for precision work in tight-tolerance environments. Installed by machinists and CNC operators in production and job-shop settings.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling applications requiring both stock removal and finish passes without a tool change. The square end geometry supports shoulder milling, slotting, and profiling operations. With a 12 mm length of cut and 50 mm overall length, it fits standard toolholding systems used in vertical machining centers and CNC mills. The centercutting design allows plunge entry. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4 mm cutting diameter with matching 4 mm straight shank for direct collet or toolholder fitment\u003c\/li\u003e\n\u003cli\u003e3-flute design balances chip clearance with cutting edge contact for roughing and finishing\u003c\/li\u003e\n\u003cli\u003e37-degree helix angle promotes smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eZrN coating reduces tool wear and thermal buildup during extended cuts\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for high hardness and dimensional stability\u003c\/li\u003e\n\u003cli\u003eCentercutting square end supports plunge milling and full-profile finishing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC vertical machining centers and manual mills accepting 4 mm straight shank end mills in compatible collet or toolholding systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or spindle is locked out before inserting or removing the end mill. Seat the shank fully in the collet or toolholder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before initiating a cutting program.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 4 mm (0.1575 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: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 12 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Square\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\u003eChipbreaker\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 95171402\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743925862706,"sku":"95171402","price":79.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/affc6ad29b161f930552cddf00ff7906.jpg?v=1788851401","url":"https:\/\/voomisupply.com\/products\/accupro-95171402-end-mill-4mm-3-flute-solid-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
