Corded vs. Cordless: Making the Right Choice

While this article focuses on cordless options, it’s worth addressing the ongoing debate between corded and cordless rotary hammers. As noted in discussions on r/Tools, cordless technology has advanced significantly, but there are still scenarios where a corded model might be preferable.

Cordless rotary hammers offer unmatched portability and convenience, making them ideal for job sites without power access or for tasks requiring mobility. However, for extended heavy-duty use or when maximum power is needed, some professionals still prefer corded models.

The consensus among professionals seems to be that for residential work and most commercial applications, today’s premium cordless rotary hammers provide more than enough power and runtime. Only in the most demanding industrial applications might a corded model still hold a significant advantage.
