Built from micrograin solid carbide, this tool delivers the rigidity and wear resistance required for productive cuts in hardened steels, stainless steel, cast iron, and non-ferrous alloys. The mill measures 0.5625 inches in diameter with a 1.25-inch length of cut and a 3.5-inch overall length. A 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. The nACRo coating provides thermal stability and oxidation resistance at elevated cutting temperatures, extending tool life in dry and semi-dry machining environments. Intended for installation in CNC machining centers by skilled machinists and toolroom operators.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits precision milling operations in job shops, production machining facilities, and tool-and-die environments. It is appropriate for finishing passes on contoured surfaces, cavity work in mold and die applications, and profiling cuts where a controlled ball nose geometry is required. The right-hand cutting and right-hand flute direction make it compatible with standard CNC spindle configurations. The 9\/16-inch shank diameter fits standard collets and end mill holders sized for that diameter. No extended reach geometry is present, so this tool is best applied in setups with adequate spindle-to-workpiece clearance.\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\u003enACRo coating provides oxidation resistance and thermal stability in high-temperature cuts\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral configuration supports higher feed rates and improved surface finish\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with right-hand cut and right-hand flute direction\u003c\/li\u003e\n  \u003cli\u003eClose diameter tolerance of +0.000 to -0.002 inches ensures dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers with standard collet chucks or end mill holders accepting a 9\/16-inch shank diameter.

Ensure the spindle and tool holder are clean and free of debris before seating the shank. Verify shank clamping torque per the tool holder specification before operating. Always confirm spindle rotation direction matches the right-hand cutting geometry of this mill before initiating a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5625 inches (9\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches (1-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches (3-1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5625 inches (9\/16 inches)\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: nACRo\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 to -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 12179241\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51753786081586,"sku":"12179241","price":201.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee82fc6eb7f8370f036a4008b5538dc4_c9917717-56b8-4073-b145-0983a26f3793.jpg?v=1788940657","url":"https:\/\/voomisupply.com\/products\/accupro-12179241-ball-end-mill-0-5625-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
