High Hardness and Wear Resistance: Tungsten carbide drill bits are made from hard alloy, featuring high hardness and superior wear resistance. This allows the tungsten carbide drill bits to maintain good cutting performance when processing materials with higher hardness. In this case, using spot drills helps reduce the stress on the drill bit at the start of drilling, further protecting the drill bit and extending its lifespan.
Cutting Efficiency: The high hardness and wear resistance of tungsten carbide drill bits result in higher cutting efficiency during the cutting process. Using spot drills ensures that the drill bit quickly reaches a stable cutting state at the beginning of drilling, reducing machining time and improving production efficiency.
Stability: Tungsten carbide drill bits have good stability, able to maintain hardness and strength in high-temperature environments. Using spot drills can reduce the impact of cutting heat on the drill bit during the drilling process, further improving drilling accuracy and lifespan.
Cutting Force Balance: Tungsten carbide drill bits can better balance cutting forces during the cutting process, reducing vibration and wobble. Used in conjunction with spot drills, this helps to further reduce eccentric error during drilling, improving roundness and positional accuracy.
