Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding cutting applications. The tool features a 4.00 mm cutting diameter, a 12.00 mm length of cut, and a 45-degree helix angle that promotes efficient chip evacuation and reduces cutting forces. A zirconium nitride (ZrN) coating adds surface hardness and heat resistance, extending tool life in high-cycle production environments. This end mill is intended for use by machinists and tooling specialists working in CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finishing and semi-finishing passes in mold work, die making, and general precision machining where a ball-nose profile is required. The 4.00 mm shank diameter matches the cutting diameter, making it compatible with standard ER collet systems and precision shrink-fit holders commonly found in vertical and horizontal machining centers. The right-hand cut and right-hand spiral flute geometry support conventional and climb milling strategies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for superior hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eZrN coating enhances surface hardness and thermal resistance during high-speed cutting\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes efficient chip flow and reduces cutting pressure\u003c\/li\u003e\n\u003cli\u003e4.00 mm ball nose profile for contoured surface milling and finishing passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction with spiral flute geometry for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 50.00 mm overall length for reach in standard setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit tooling solution for CNC machining centers accepting 4.00 mm shank end mills via ER collet chucks, shrink-fit holders, or equivalent precision toolholding systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool changer or spindle is locked out before inserting or removing the end mill. Use a calibrated torque wrench on collet nuts and verify runout with a dial indicator before beginning a cut. Do not exceed the tool manufacturer's recommended speed and feed parameters for the workpiece material and coating type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 12.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: 0.5 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 95171372\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739649442098,"sku":"95171372","price":79.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c4c4716e81e40a3020e096970e47b33.jpg?v=1788817335","url":"https:\/\/voomisupply.com\/products\/accupro-95171372-ball-end-mill-4mm-2-flute-solid-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
