Two-flute ball end mills
The EB220 series is a professional-grade ball end mill designed for semi-finishing and finishing of general-purpose metal curved surfaces. It is widely used in mold making, complex surface machining, and other applications requiring high precision. Featuring a 2-flute, 38° helix angle design with a nano-blue TiAlN coating and a high-toughness carbide substrate, it combines high rigidity, low cutting resistance, and excellent spherical precision. It is an ideal choice for machining curved surfaces, contours, and root clearing in various materials such as steel, stainless steel, and aluminum alloys. Advanced grinding and manufacturing processes ensure cutting stability.

Design details engineered for accuracy, tool life and process stability.
Enables smooth, progressive cutting, reducing tool impact and vibration. Surface finish can reach Ra0.4μm or lower, suitable for machining curved surfaces of high-hardness materials.
Surface hardness HV3400, high temperature resistance up to 1400°C, maintaining excellent wear resistance even under high-speed cutting, reducing the risk of coating peeling.
Edge radius controlled within 0.01mm, balancing edge sharpness and chip resistance, suitable for machining high-hardness materials.
Ball end precision controlled within ±0.005mm, excellent spherical surface finish, enabling precise surface shaping and root clearing.
The cutter head diameter is 12% larger than that of ordinary ball end mills, improving tool rigidity and maintaining machining stability even at high feed rates.
Standard straight shank compatible with ER collets, allowing for quick clamping on various CNC machining centers and milling machines.
Using ultra-fine tungsten carbide alloy as the base material, the double-flute design enhances chip removal, especially effective when machining soft materials (such as aluminum alloys and copper alloys).
