It is a replacement for carbon steel tools, specifically bits and blades, though both may still be used commonly. Its development has a number of advantages over carbon and thus is considered a more popular choice for such applications. COBALT Cobalt drill bits are particularly successful in cutting through hard metals such as stainless steel and cast iron, although they can be used for softer materials, too. Cobalt drill bits are not made of pure cobalt, but rather a steel alloy with 5 to 8 percent cobalt. The 5-percent alloy is known as M35 grade, and the 8-percent alloy is M42. The cobalt increases the strength of the steel and makes it more heat-resistant; this is an important factor in drilling hard materials because the friction of metal against metal can produce high temperatures that damage the material or the drill bit. Cobalt Double Margin bit with Pilot Double margin drill bits have an additional margin ground behind the leading margin, providing twice the number of contact points. This second margin performs various functions to improve hole quality. The trailing margin burnishes the cavity, making a true hole and smoother finish, helping to provide a more concentric drilled hole. STEP DRILLS Step drills are drill bits that are shaped like a cone and are comprised of multiple sizes, or steps, in a single package. These can be anywhere from two to 13 different bit sizes in increments of 1/32 inch to 3/4 inch, or 4 to 12 millimeters. The user simply starts the drill bit into the part to be drilled and pushes the bit in until the desired size hole has been drilled. The benefit is a step drill bit is that most are rated to last up to six times longer than a conventional drill bit.
