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.Thick core for increased rigidity in hard materials.
4.Ground flutes provide fast chip removal to maximize accuracy and efficiency along the full working surface of the bit.
5.DIN 338 jobber series drill bits are ideal for many trade and industrial projects.
