Premium Cobalt Straight Flute Step Drills for hardened materials. USA

Premium Cobalt step drill bits sometimes known as a cone drill are best known for their excellent performance in drilling hard materials such as stainless steel, high carbon steel, cast iron, and other metals.

These bits also have a superior heat resistance making them stay much sharper for much longer.

These Step Drill bits come on a Hex, quick release shank for maximum control and speed.

Great for quick, large hole-making on hard material!
