What Can You Use to Cut Iron? (How To)

Iron has been used in construction for centuries and cutting it has required both strength and perseverance.

You can cut iron with an angle grinder fitted with a metal-cutting disc. Cutting discs wear down quite quickly, so using a diamond blade is both quicker and more cost-effective than an abrasive cutting disk. It will cut through many different kinds of metal, including rebar, angle iron, and cast iron.

Tools to cut Iron

There are various other power tools and hand tools available to cut iron and each one is designed for a specific purpose.

Depending on what size the piece of metal is that you are cutting, it will determine what tool is appropriate. While a hacksaw can cut through rebar, it will take a long time, so using a cutting disk or plasma cutter is a much more efficient way to achieve your goal.

Can You Cut Cast Iron with A Plasma Cutter?

Plasma cutters have become cheaper and are now an affordable tool that you’ll find in many DIY workshops.

Generally, materials cut with a plasma torch include steel, stainless steel, aluminum, brass, and copper, though, other conductive metals such as cast iron may be cut as well. A plasma cutter cuts through electrically conductive materials utilizing an accelerated jet of hot plasma.

Cast iron is extremely heavy and is usually more difficult to cut than standard steel. When attempting to cut cast iron, you may struggle to find a suitable tool to use.

While it is possible to cut cast iron with a plasma cutter torch, this method is not recommended.

Ferrous blades are the ideal option for cutting metals that contain iron, like stainless steel or cast iron. With regards to softer metals, you will need a non-ferrous blade when cutting materials such as aluminum or copper.

Can You Cut Cast Iron with A Dremel?

A Dremel multitool is a handheld rotary tool that uses a variety of abrasive and cutting attachments and accessories.

The cutting disks used in a Dremel tool are constructed from a hard abrasive and can be used for working various types of metal types, like aluminum, copper, cast iron, and even hardened steel, but it is not a suitable tool for cutting through iron.

This versatile handheld tool creates power with a spinning rotary shaft. It has a cutting or grinding tool affixed to the tip.

Dremel tools can be used on wood, metal, glass, electronics, plastic, and various other metals. It is ideal for grinding, sanding, cutting, and carving.

Some may be confused as to what the difference is between a drill and a Dremel. The main difference is that a Dremel is smaller in size and power compared to a drill. Unlike a drill, the Dremel does not have a handle.

While a Dremel (30,000rpm) has a larger torque than a drill (1500rpm), it cannot produce the same amount of raw power needed to cut larger pieces of metal.

Can You Cut Iron with A Hacksaw?

This versatile type of saw is useful for cutting a variety of materials around your home. Both metal and non-metal.

A good old-fashioned hacksaw is great for cutting cast-iron pipes. However, when using this tool, an enormous amount of effort is needed and can result in copious amounts of hard work. It also may take a substantial amount of time, especially if you have several pipes to cut.

A bonus of owning a hacksaw is that it can successfully cut through practically any metal, plastic, and wood as it was specifically designed to do so.

These tools are a variant of the traditional hand saw, typically used for cutting wood, but have become a staple tool for professionals and hobbyists alike.

Can You Cut Angle Iron with a Miter Saw?

It is most definitely possible to cut angle iron with a miter saw. It is dependent on whether you have a good blade, and a decent miter saw motor. You will be able to take on quite a few small home repair or remodeling jobs involving metalwork so long as the metal is securely clamped.

Miter saws are typically used to make quick, accurate cuts in materials like crown molding, framing materials, and narrow pieces of wood.

While angle iron is used to join parts of a wooden structure or to create a frame, cutting it with a miter saw is not the norm.

Mitre saws were originally and traditionally used for cutting wood, but with the correct blade, they can make light work of cutting through steel and aluminum profiles at any angle.

Can You Cut Iron with Water?

Despite the initial idea being quite crazy, it turns out that water does an excellent job of cutting through a variety of materials.

You can successfully cut iron with water so long as the spray is kept coherent at very high pressure. Waterjets can cut because the spray is channeled through a very narrow, jeweled nozzle at enormous pressure. Unlike metal cutters, a waterjet never gets dull and cannot overheat.

In industrial workshops today, computer-controlled waterjets and abrasive jets are used to cut through both metallic and non-metallic materials. The plain water-abrasive mixture leaves the nozzle at more than 900mph, cutting through steel like a knife through butter.

Waterjets can cut through various materials such as marble, granite, stone, metal plastic, wood, and stainless steel.

Waterjet cutting systems are pressurized up to 90,000 PSI. The water at this pressure is then released through a small hole machined into a diamond or sapphire. This is usually in the range of 5 to 15 thousandths of an inch in diameter.

When considering a pure waterjet, cutting capabilities are ideal for softer materials like fabrics, rubber, or metal foils. Adding an abrasive allows you to cut anything you like.

Can You Cut Iron with a Grinder?

Primarily, grinders are utilized for refurbishing and polishing metal materials.

A grinder can be used on many different projects and it can cut iron with relative ease. While it is not specifically designed to cut metal, with a suitable cutting disk attached, grinders make very good cutting tools. When grinding cast iron, a silicon carbide abrasive is recommended.

When working with hard, brittle materials, you will generally require a wheel with a fine-grit size and a softer grade.

Hard materials resist the penetration of abrasive grains. This causes them to dull quickly.

How To Cut Iron Properly?

When considering cast iron, we know that it is both tough and durable. When cutting through solid cast iron, a saw or cutting tool with a diamond saw blade would be the best choice to cut a straight line. You can also use a manual hacksaw, especially when cutting cast-iron pipes.

Remember that before cutting metal, you will need to wear the appropriate safety gear. And if you are wondering what can you use to cut iron, then choose the right blade for the material, preferably a diamond blade or a silicon carbide abrasive.
