Iron Mfg Tools For Cutting Metals

[Kizzy Burnworth]

Steelroofing and trim should be cut with nibblers, tin snips or a profile shear. Although Champion Metal of WA. does not advocate the use of a saw, the reality is many people use a power saw in some manner. There are two concerns when using a saw. First, be sure that no burrs are left on the ends of the panel. The rough edges are not protected and will rust. Second, the filings coming off the blade are hot and will adhere to the surface of the panels and these will rust. Be sure all filings are removed from the surface as they will rust and pit the surface of the sheet.

I used to use a 7 1/4" metal cutting wheel on a circular saw. Works good, but wheel wears down fairly fast. There are also some good shear attachments that mount on drills. I'd advise you to make the cuts on the end going to the top, not the exposed bottom. Definitely have some spray paint or primer to treat the cut end, because it will rust. If you put the cut ends at the top under your ridge cap, you will be fine. The other alternative is to buy your panels cut to length before they land on the job. Several manufactures cut to order such as Everlast Metal Roofing.

1 - Electric shears and / or nibblers. These are in my opinion, the best tools you can buy. Shears work fine while nibblers are designed more specifically for corrugated or curved panels. If you're a professional, this is what you need to buy.

4 - Aviation snips for little notches you might need to make. You can try different brands, I have, but Wiss is a little more money, but still my favorite.I don't think you need a set like this, I honestly have never used the yellow ones. You can buy the green and reds separately and even angled ones that are helpful.

Go find your old used circular wood cutting blades, without carbide teeth, or buy the cheapest circular saw blade you can buy. There is no point in messingup a good carbide tooth blade. They can be easily re-sharpened.

So take the used or new blade and stickit in a vise. Use an angle (side) grinder to makeall the teeth no wider than the rest of the blade.This is easy to do. If you do not have an anglegrinder (like one a welder uses) then put the cheapblade in the circular saw and turn it against agrinding stone or grinding wheel. When you are done the teeth are 1/16 wide.

All the grinding will be on thesides of the teeth. Do not grind the teeth off of the blade , only the sides of the teeth. When you finish, the blade's teeth will be thinner, but the ends of the teeth are not shorter. This should takeonly a couple of minutes. Do not make the blade anythinner except at the teeth. This blade has no need of sharpening. It dulls up as soon as it hits themetal - and cuts fine.

YOU, however, WILL need earplugs. The easiest placeto cut metal roofing is on the grass. The metalsheets slide around too much on a bench or table.Lay a 2x4 on the grass and hang the end of the metal panel over the 2x4. Now your blade is not digging into the turf as you cut.

I have cut painted and unpainted Galvalume metal roofing this way. If you get hung up or the bladeis pinched by the metal, stop and adjust. The bladeneeds to keep moving so it does not get hot andmess up the paint on painted galvalume.

P.S.You can get clean edges by running a 4 inch anglegrinding wheel along the edge where you cut. Thisshould be done RAPIDLY, to just remove the burrs.If you stop moving, the grinder will dig in whereyou don't want it to. Don't push hard on the wheel- just lightly remove the burrs left over from cutting. This makes a nice smooth edge if your cutwas straight.

The roofers I've seen working with metal sheet cladding have usually used an air or electric nibbler to cutting single sheets. Composite sheets (metal, insulation, metal sandwich) generally get cut with a carbide tipped circular saw.

Metal may be the most versatile building material on earth, but turning raw materials into a polished final product requires skill and specialized tools. Metal is often challenging to work with, and each metal possesses unique properties and characteristics that require a variety of cutting tools to fabricate them.

These tools are best for making rough cuts in sheet metal and for working with thin materials. These snips can be challenging to keep straight while cutting, and the cut often has burrs or jagged edges throughout that require finishing later on.

A circular saw is another popular woodworking tool that you can outfit with specialized blades for cutting metal. There are blades for cutting aluminum and abrasive cutting wheels that work well for cutting tubes or bar stock.

Hole saws are bits that attach to a drill or drill press for cutting circles. These hollow cylinder bits usually have fine teeth to cleanly cut through a variety of sheet materials. Bi-metal hole saws are preferred, as they offer the most versatility for cutting different metals.

A cut-off tool is similar to an angle grinder but with smaller 3 inch cut off wheels, perpendicular to the handle. Cut-off tools are available in electric and pneumatic varieties, and they come with an abrasive cut off wheel that makes quick work of sheet goods, old bolts, fasteners, and tack welds.

Rotary tools and die grinders, commonly known by their most popular manufacturer (Dremel), are precision tools that are very useful for fine detail work. These tools accept various cutting, grinding, or polishing bits, which attach to a collet at the bottom of the tool.

Rotary tools are versatile, and while you can use one with virtually any material, die grinders are made especially for cutting and grinding metal. Their compact size and full range of motion allow you to cut curves, straight lines, and fine details that are impossible with other tools.

An oxy-acetylene or cutting torch is a powerful tool that can easily cut virtually any metal, regardless of thickness. These are those torches you often see in movies when bank robbers are trying to break into a vault. Compressed gas tanks of oxygen and acetylene fuel these torches. You dial in the proper ratio of these two gases to create a scorching hot and focused flame that can cut through any material with ease.

A cutting torch is ideal for cutting through heavy stock materials, steel bars, beams, and other building materials. For thinner materials or painted surfaces, the flame from the torch will burn and warp them.

Plasma cutters are powerful machines designed specifically for precision metal cutting, making them a staple in industrial and fabrication settings. These devices function by generating a high-velocity stream of ionized gas (plasma), which melts and blows away the metal, resulting in a clean, rapid cut. Plasma cutters are suitable for a wide range of metals, including steel, stainless steel, and aluminum.

To ensure safety, always wear appropriate gear such as safety glasses and hearing protection, as the cutting process can be noisy and generate sparks. Keep the saw steady and use a slow, controlled cutting motion to produce clean and accurate cuts. Additionally, inspect the blade regularly for sharpness and signs of wear.

Metal shears are specially designed hand tools that can cut sheet metal and thin metal stock. They excel at providing precise, clean cuts with minimal distortion, making them an ideal choice for intricate metalwork. To use metal shears effectively, begin by marking the cutting line on the metal and then insert the material between the blades of the shears. Apply steady pressure by squeezing the handles together.

Allow the shears to cut through the metal along the marked line. The type of metal and its thickness may require different types of metal shears, such as aviation snips or compound leverage snips. Regularly inspect the blades for sharpness and signs of wear to ensure consistent cutting performance.

Learning how to cut metal safely and accurately is an invaluable skill for anyone involved in metalworking. Whether you opt for traditional hand tools like hacksaws and shears or choose power tools like angle grinders and plasma cutters, understanding proper techniques and safety precautions is essential. By mastering these tools and methods, you can achieve precise, clean cuts in metal, elevating your metalworking projects to successful and satisfying endeavors. Remember that safety should always be your top priority, and wearing the appropriate protective gear is essential for every metal-cutting task.

The creation of the lathe was mainly for artisanal purposes. However, due to its versatility, it can create specialty metal parts that have practical uses such as doorknobs, nuts, screws, and even gun barrels.

Drills are also very common when it comes to metal-cutting machinery. These employ a drill bit and a powerful motor that drives the chiseled edge of a drill bit into a certain metal component while spinning at a very high RPM (revolutions per minute).

When one thinks of hot and exposed flames, especially oxy-acetylene torches, one usually thinks of welding. However, torches can also be used for cutting extremely tough and hard-to-cut metal parts. Because its power mainly being drawn from extreme heat, oxy-acetylene torches can be set to cut metals of any thickness. Most of the time cutting jobs done by torches are messy, but it still largely depends on the worker. This is why one would usually require grinding and sanding jobs to make the cuts smoother.

A metal cutting mill is a cutting tool in which a component is placed fixed on the workspace and is exposed to a high-speed rotating cutter similar to that of the drill. The cutter spins at a high RPM and is very accurate when it comes to fine details, corners, and dimensions. Because of this, millers have a wide application in production work.

Water may not be the most common tool when it comes to cutting metal, after all, water is usually cool and soothing. However, water is extremely versatile. When water spews forth at extremely high pressures concentrated at a small point, water is powerful enough to cut through steel.
