Product details:
Ordinary drills are fine for making small holes, but they often struggle with wider ones. Designed with a tungsten carbide tipped blade, this saw can easily chew through wood, and work well when cutting through brick, plastics, and tile up to a hardness of 6. In fact, it can cut up to 50% faster than standard hole saws. This blade can be used with the spyder rapid switch and rapid core eject (sold separately). That makes switching out spyder hole saws for different sizes as easy as pressing of a button, and they can also be adjusted for drilling holes at different angles. With those features, the Spyder Deep Cut Hole Saw isn't just the tool to get the job done, but the tool to get it done quickly.
