As a result of using these bits, I found that my hole-cutting projects have become much easier to handle... They cut through concrete like butter making such a daunting task go by surprisingly fast. The carbide construction ensures that these tools will last for a long time, reducing the chances of the bits becoming dull as a result of frequent use in industrial and scientific settings. However, the PRICE point might deter potential buyers who may be hesitant to spend more on cutting tools..
