Selecting the appropriate drill and drill bit is crucial for drilling metals like steel, aluminum, brass, copper, and cast iron. Steel requires hard metal drills; aluminum is easier to drill due to its lightweight properties. Brass and copper are soft metals but can cause uneven holes as they may grab the drill bit. Cast iron is brittle, requiring specialized carbide or cobalt bits and cutting fluid to minimize heat and friction during drilling.
"It's tough and durable, making it an excellent choice for many projects. Steel requires you to use drills that are designed for hard metals."
"It's a much easier metal to drill because of its lightweight and flexible nature."
"It can be tough to get even holes with these metals because they can grab at the drill bit."
"You'll need specialized bits (such as carbide or cobalt) and plenty of cutting fluid to reduce heat and friction."
