Features
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 less pressure. Will not “walk” or “wander”.
3.Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance. 120 Piece Titanium Drill Bits Kit
