Built from micrograin solid carbide, it features a 5\/8 inch cutting diameter, a 2 inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation and smooth surface finishes. The tool carries an nACRo coating, which improves heat resistance and extends tool life in demanding high-speed machining environments. With 4 right-hand spiral flutes and a right-hand cutting direction, it delivers consistent material removal on CNC machining centers and manual mills alike. Installation and operation are handled by machinists and CNC programmers working in job shops, toolrooms, and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for profiling, contouring, slotting, and finishing passes in molds, dies, and complex 3D part geometries. It performs well in alloy steels, stainless steels, hardened steels, and similar materials where the nACRo coating provides a thermal and chemical barrier. The 5\/8 inch shank diameter fits standard ER collet chucks, side-lock holders, and shrink-fit toolholders in that bore size. The 6 inch overall length gives clearance for deeper cavity work while maintaining rigidity appropriate for the diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003enACRo coating for extended tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes for balanced material removal and surface finish quality\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 5\/8 inch shank for direct compatibility with standard toolholders\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of plus 0.000 \/ minus 0.002 inches for consistent fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills accepting a 5\/8 inch shank diameter toolholder, including ER collet, side-lock, and shrink-fit systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following shop-standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the end mill. Verify collet or holder bore size matches the 5\/8 inch shank before tightening. Follow the toolholder manufacturer torque and runout specifications to avoid premature tool wear or breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\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: nACRo\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: 0.25 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: 12179303\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738064060722,"sku":"12179303","price":453.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee82fc6eb7f8370f036a4008b5538dc4_59fb2094-e4cf-4431-974e-271f612cf267.jpg?v=1788795915","url":"https:\/\/voomisupply.com\/products\/accupro-12179303-ball-end-mill-5-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
