The lifespan of drill bits is mainly influenced by various factors, including drill material, processing object, and usage environment. The following is a detailed analysis and summary of the lifespan of drill bits:

Drill material:
High speed steel drill bit: With a relatively short service life of about a few hundred holes, it is suitable for drilling low hardness materials. Its lifespan ranges from several hours to tens of hours, depending on the frequency of use and processing conditions.
Hard alloy drill bits: have a relatively long service life, up to several thousand holes, suitable for materials with higher hardness. Under ideal usage conditions, its lifespan may reach tens to hundreds of hours.
Diamond drill bit: With a longer service life, it can hold tens of thousands of holes or more, and is suitable for processing high difficulty and superhard materials in specific fields. However, due to the fact that diamond drill bits are mainly used for processing under extreme conditions, their actual usage time may vary depending on specific conditions, but they can usually reach hundreds of hours or even longer.
Processing object:
The hardness and shape of the processed object can affect the degree of wear of the drill bit. When processing objects with high hardness and irregularity, the wear on the drill bit is greater, thereby shortening its service life.
Usage environment:
Factors such as high or low working temperature, poor lubrication, etc. can accelerate the wear of drill bits and reduce their service life.
Other factors:
The accuracy, coating quality, maintenance, and management of drill bits can also affect their service life. Drills with higher accuracy, better coating quality, and proper maintenance usually have a longer service life.
Summary:
The length of drill bit lifespan is a relative concept, which depends on the comprehensive influence of various factors. Under ideal usage conditions, the lifespan of hard alloy drill bits may reach tens to hundreds of hours, while the lifespan of diamond drill bits may be longer. However, in practical applications, the actual service life of drill bits may vary due to the influence of machining objects, usage environments, and other factors. Therefore, in order to extend the lifespan of drill bits, it is necessary to choose appropriate drill bit materials, processing parameters, and usage methods, and carry out regular maintenance and management.
