Because of its increased red hardness and enhanced wear resistance, High-Speed Steel (HSS) is a favored material for use in drill bits. These characteristics enable drilling at faster speeds and through tougher materials. However, HSS is a brittle material, which can cause it to break easily when subjected to excessive forces. Therefore, it is important to select a drill bit design that does not apply too much force on the material being drilled. This could lead to premature failure of the bit itself or other parts of the drilling system. Factors such as surface roughness, cutting speed, and feed rate should be taken into account when choosing a drill bit design. For example, polycrystalline diamond compact (PDC) bits tend to be more durable than HSS bits because they are less sensitive to force applications. Furthermore, PDC bits can reach higher rotational speeds before experiencing fatigue. This makes them useful for longer drilling campaigns or where the process requires high precision during all stages of operation. Metal properties that would be important for a drill bit include hardness and weight. The harder the material, the better it will resist wear and tear from drilling. Additionally, the heavier the material, the more inertia it will have, which will help prevent overshooting a target depth when making fine adjustments to the bit's position during the drilling process.
