This is a nice chunky bit, but not as heavy-duty as it might at first appear. The fact that the shank is much smaller in diameter than the bit (which makes this a Silver & Deming style of drill) means it can only be used with softer, or thinner, material. If you want a one inch (2.5cm) hole through a thick piece of hard steel, you should consider a drill bit with a full-diameter shank, and a machine big enough to hold it.
