If we turn the drill bits back to the industry. Drill bits have always been playing an important role in manufacturing. Various drill bits such as carbide drill bits and High-speed steel drill bits are generally used in the manufacturing industry of wood, metal, fiber, and so on. These drill bits work at high speed and high temperature, but they turn each piece of wood and metal to be a perfect, smooth, precious finished product. Drill keeps on working day and night with no stop and high output. There is no tolerance that could escape from the drill bit, perfect work with no error is what the drill bits always pursue after.
That is why in China, the persistent, meticulous person will be associated with the drill bits. If everyone has a drill-like spirit, no need we bother if the work can not be finished well. Surely.
