What is the hardest things a bolt cutter can cut?

A bolt cutter is a hand tool used to cut through bolts, rods, and other metal objects. The cutting blades of a bolt cutter are typically made of hardened steel, which makes them very hard and durable. However, there are some materials that a bolt cutter cannot cut through, including:

- High-strength steel: High-strength steel is a type of steel that has been alloyed with other elements to increase its strength. This makes it much more difficult to cut than mild steel or other common metals.

- Stainless steel: Stainless steel is a type of steel that has been alloyed with chromium to make it resistant to corrosion. This also makes it more difficult to cut than mild steel.

- Cast iron: Cast iron is a type of iron that has been melted and then poured into a mold. This gives it a very hard and brittle structure that can be difficult to cut.

- Titanium: Titanium is a lightweight and strong metal that is often used in aerospace and other high-tech applications. It is also very difficult to cut, even with a bolt cutter.

If you need to cut through a material that is harder than a bolt cutter can handle, you will need to use a different tool, such as a hacksaw or a power saw.
