Can rotary hammers be used with any type of drill bit?

Yes, as they have universal chucks
No, they require specific drill bits
Yes, but only specific brands
No, they accept only high-speed steel bits

The correct answer is: No, they require specific drill bits

Rotary hammers are specifically designed to perform heavy-duty drilling tasks, particularly in hard materials like concrete and masonry. To effectively utilize this tool, it is crucial to use drill bits that are specifically engineered for rotary hammer applications. These bits typically feature a shank style that fits precisely into the tool’s chuck mechanism, allowing for the hammering action to be transmitted effectively. Using the wrong type of drill bits can lead to inefficient performance, potential damage to both the bit and the tool, and can even pose safety risks. For example, standard drill bits or those not designed for the impact action may not withstand the forces generated by a rotary hammer, leading to breakage or ineffective drilling. Therefore, it is essential to select the specific types of drill bits that are compatible with rotary hammers, such as SDS (Slotted Drive System) or other specialized designs, to ensure optimal performance and safety.
