What makes this drill bit stand out from others is that it has an hex bit on the end. What this hex bit allows you to do is to be able to switch out from bit to bit in a very fast manner without having to adjust your drill size everytime and you can also use it with a impact driver. This bit is made of high grade steel with a black finish. The combination of the 135 degree split tip and parabolic flute allows for very fast and efficient drilling while keeping the bit at a low temperature and debris out of the way.
