2 Flute Tungsten Steel End Mill | 5Pcs CNC Milling Cutter for Aluminum/Copper/Low Carbon Steel | 3.175 x 17 x 45mm Engraving Bit with Nano Blue Coating

Produktbeschreibung

Sturdy Tungsten Steel Build - These 2 flute end mills boast 90HRC hardness and extended service life, ensuring 3X longer lifespan than standard carbide bits. Ideal for high-speed CNC machining of metals. Effective Chip Removal Design - Double-flute milling cutter features improved spiral angle to expel chips 40% quicker, avoiding material buildup during continuous use on aluminum and soft metals. Nano Blue Treated Exterior - Mirror-polished end mills with oxidation-proof coating reduce friction by 25% while protecting against particle adhesion. Suitable for detailed engraving on copper and non-ferrous alloys. Multi-Material Adaptability - CNC engraving bits handle diverse materials including low carbon steel (A3/Q235), cast iron, and plastic composites with consistent 0.01mm tolerance for flat/slot milling. Accurately-Shaped Geometry - Each 3.175mm shank end mill undergoes optical measurement to ensure ±0.002mm runout tolerance for industrial-grade part finishing on milling machines.
