Produktbeschreibung

Professional-grade Tungsten Carbide Construction - These CNC milling cutters deliver exceptional hardness (90HRA) and longevity, maintaining sharpness 3X longer than standard steel bits. Ideal for high-speed machining of circuit boards and metal parts. Accurate Coating - Ball nose end mills feature enhanced TiN coating that reduces friction by 40% while increasing thermal tolerance to 600°F. Ensures smooth milling of copper, stainless steel, and hard plastics without material buildup. Engineered Reinforced Strength - 3.175mm shank diameter provides 25% greater rigidity compared to similar bits, avoiding breakage during deep groove cutting (up to 12mm depth) in aluminum alloys and composite materials. Multi-Material Versatility - Sharper 2-flute design handles 5X more cutting operations than competitors. Suitable for DIY enthusiasts and professionals working with PCBs, acrylics, wood carvings, and jewelry making. Complete 10-Piece Starter Kit - Includes 5 size options (1mm-3.175mm) with two duplicates of each. Each bit undergoes 3-stage polishing for smooth performance, backed by 30-day replacement policy.
