What happens if the wrong tool is used on case-hardened steel?

Using the wrong tool on case-hardened steel can lead to the tool breaking, which can pose serious risks to the user. Case-hardened steel is treated to enhance its surface hardness, making it more resistant to wear and deformation. As a result, tools that are not designed to handle such materials may experience excessive stress during use.

When a tool is subjected to forces beyond its capabilities, it can fracture or shatter, potentially sending sharp fragments flying. This creates a hazardous situation, as any nearby personnel could sustain injuries from these projectiles. Having the right tool is essential for both efficiency and safety, particularly when working with materials that have specific mechanical properties like case-hardened steel.

While there are other concerns associated with improper tool use, such as the risk of personal injury from cutting too quickly or dust igniting, the primary danger remains the likelihood of tool failure and the resultant risk of injury to the operator or those around them.
