1.Cobalt drill bits are more expensive than other drill bits, but if you regularly drill through metal, they are a good investment since they tend to last longer.
2.No center punch is needed—the aggressive 135° Quick-Cut points are self-centering and penetrate quickly with lesspressure. Will not "walk" or "wander".
3.Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance.
