With a 0.625-inch diameter and a 3-inch length of cut, this single-end tool delivers deep-reach capability in a rigid carbide body. The nACRo coating provides enhanced heat and wear resistance, extending tool life in abrasive and high-temperature cutting conditions. Four right-hand spiral flutes with a 40-degree helix angle promote efficient chip evacuation and smooth cutting action. Machinists and CNC operators in job shops, tool rooms, and production environments rely on this geometry for contour milling, profiling, and 3D surfacing work.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling ferrous and non-ferrous materials where a ball-nose profile is required for 3D contour work, radius floor features, and die-and-mold applications. The micrograin carbide substrate supports higher surface footage and feeds compared to conventional carbide grades. The 40-degree helix is well matched to medium-to-hard workpiece materials. The 0.625-inch shank diameter matches the cutter diameter, allowing use in standard collet chucks, hydraulic holders, and shrink-fit toolholding systems designed for that bore size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.625-inch ball nose diameter with a 3-inch length of cut for deep-reach contouring\u003c\/li\u003e\n\u003cli\u003enACRo coating for improved heat resistance, wear resistance, and tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes at a 40-degree helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and edge integrity at higher cutting speeds\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with a 6-inch overall length for extended reach setups\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 to -0.002 inches for consistent, predictable sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills equipped with standard 0.625-inch bore collet chucks, hydraulic holders, or shrink-fit toolholders.

Ensure the machine spindle is fully stopped and the tool changer or spindle is locked out before changing tooling. Seat the shank fully in the holder to the recommended gauge length and torque the clamping mechanism per the toolholder manufacturer specifications. Verify runout at the cutting edge with a dial indicator before commencing a cut, as excessive runout will accelerate edge wear and reduce surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 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: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: nACRo\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\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\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 12179294\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746672181554,"sku":"12179294","price":476.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee82fc6eb7f8370f036a4008b5538dc4_e6dc5a48-e360-4053-bc83-e5125d564e91.jpg?v=1788872423","url":"https:\/\/voomisupply.com\/products\/accupro-12179294-ball-end-mill-0-625-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
