The primary advantage of hardened drill bits lies in their ability to maintain their sharpness and cutting edge under heavy loads and repetitive use. Unlike standard drill bits, which can quickly become dull and ineffective, hardened drill bits are made from materials that are specifically formulated to resist wear and tear. This means that they can maintain their cutting efficiency over longer periods of time, resulting in faster drilling times and reduced downtime.
