While the high durability of hardened steel makes it suitable for various applications, it concurrently presents significant challenges in drilling due to its resistance to traditional methods.

The hardness of the material increases the risk of bit breakage and excessive heat generation during the drilling process.

This can lead to premature wear and tear, resulting in reduced efficiency and potentially costly replacements.

Furthermore, the high-speed rotation required for drilling hardened steel can cause instability, affecting the precision of the drilling operation.

It is, therefore, crucial for operators to understand these challenges and equip themselves with the appropriate tooling solutions and knowledge to overcome them.
