CNC End Mill Set, 8x 4-Flute Carbide Tungsten Steel, 2–12mm | Home of Quality Tools

Discover a versatile CNC end mill set designed for metalwork, prototyping, and engineering tasks. This eight-piece collection covers diameters from 2 mm to 12 mm, offering a complete range of cutting options for CNC machines, mills, and routers. Each cutter is crafted from tungsten carbide with cobalt, delivering high hardness, exceptional wear resistance, and reliable performance under heat. This combination helps the tools retain their edge through long sessions and challenging materials, giving you consistent results without frequent tool changes.

Precision and rigidity are built into every tool. The high-precision cutting edge is paired with a carefully engineered negative forefoot, balancing sharpness with strength. A larger core diameter adds stiffness, supporting stable cutting and efficient chip evacuation even during aggressive passes. The 4-flute design provides a favorable balance between material removal rate and surface finish, making the set a practical choice for a range of metals, including aluminum and brass, as well as tougher alloys when used with proper speeds and feeds.

Real-world use often highlights smoother chip flow thanks to the wide chip flute, producing a cleaner cut and reduced clogging in deep pockets. The chamfered shanks simplify installation, reducing tool-change time and helping you stay productive. The cemented carbide composition offers resilience to temperature fluctuations, which can occur during longer milling sessions on harder materials, helping to preserve edge geometry across multiple passes.

Applications span from hobbyist projects to professional workflows: pocketing, contouring, slotting, and profile milling on a variety of metals in CNC routers and milling machines. The eight diameters ensure you can choose the most suitable size for each step of your project, minimizing tool swapping and simplifying setup. When paired with correct speeds, feeds, and coolant (when required), these end mills can help you achieve clean slots, precise pockets, and consistent finishes.

Included items and care: 8 x 4-flute end mill cutters covering 2–12 mm diameters. High-hardness carbide tungsten steel for extended tool life. Chamfered shanks for easy installation and faster tool changes. Designed for straight shank mounting and broad compatibility with common CNC systems. For best results, follow manufacturer guidance on speeds and feeds and visually inspect edges for burrs before use.
