4 Flute Corner Radius End Mills for CNC Milling
4 flute corner radius high performance end mills are designed for CNC milling applications where strength, tool life, and edge durability are important. The corner radius helps reinforce the cutting edge compared to a sharp square corner, making these tools a good choice for profiling, side milling, pocketing, roughing, and finishing operations.
The 4 flute design provides a strong balance of cutting edge engagement, rigidity, and surface finish quality in steel, stainless steel, cast iron, alloy steels, and other machinable materials. These tools are often selected when a square end mill may be prone to corner wear or chipping during heavier milling conditions.
Use the product filters below to select the required diameter, corner radius, length of cut, reach, coating, shank size, or overall length for your machining application.
