What part of a low velocity tool requires replacement most often?

Handle
Buffer
Trigger
Motor

The correct answer is: Buffer

The buffer in a low velocity tool is designed to absorb and dissipate energy during operation, which helps to reduce vibration and protect components from wear. Given its function, the buffer is subject to considerable stress and impact during use, especially in applications involving repetitive or heavy-duty tasks. Over time, the material of the buffer can degrade, lose its effectiveness, and eventually require replacement to maintain the tool's performance and safety. In contrast, other components like the handle are typically more durable and less prone to wear under normal operating conditions, while the trigger and motor may experience less frequent failure or degradation compared to the buffer. Therefore, the buffer stands out as the part that frequently needs replacement due to its critical role in managing operational forces and its susceptibility to wear over time.
