The drill bit is an underrated piece of tool, we use this everyday object to create jewels , the mini drill bit ring and earrings is small yet its power is often underestimated, the bit cannot smash through diamond in an instant, it is a gradual process. We likened the drill bit to a human being, the human life ends through death but a lifespan of a bit ends through wear (“wear”means gradual reduction in size bit by bit). Before the lifespan of a human ends, life is continuous (life is in constant flow) .
