Best Metal Cutting Circular Saw For 2024

Power Source

Using the incorrect type of power to run your saw could compromise the quality of your job. This metal-cutting saw can be broadly divided into three varieties, according on its power source. Tell us as much as you can about them.

Gas Powered

Gasoline is used to power the motor and saw mechanism, and it is a very potent form of energy.

It is commonly employed for the purpose of slicing or chopping numerous metals.

Although it boasts impressive rates of speed and power, the use of gasoline renders this device noisy and necessitates regular upkeep to ensure it lasts as long as possible.

Weight isn't the only issue with these, though; they're also more cumbersome to maneuver than other models.

Electric Powered

The efficient motor can be powered by energy from any regular power source.

These saws are powered by cords and, in comparison to their gas-powered counterparts, produce less noise, weigh less, and are easier to handle.

Works well for cutting most metals but isn't as powerful as gas-powered saws, making it a good choice for medium- to heavy-duty projects.

It has a longer run duration, but its power cord limits it to a smaller area.

Battery Powered

There is a rechargeable battery within the saw that powers it (mostly lithium-ion or NiCad).

Light-duty jobs, such as cutting aluminum, are well suited to these cordless saws.

Heavy-duty tasks are beyond its capabilities because it continues functioning until the battery is completely depleted.

This particular saw can be used in any environment, even in tight spaces.

Comparatively weaker than the first two categories mentioned.

Metal Cutting Saw Blades

Blades used for cutting metal will be constructed differently from those used for wood or plastic. The metal saw's blades are carbide-tipped or ceramic-blend coated for durability and ease of cutting through tough materials without overheating. There is no need for coolant when using a metal blade, and the metal may be sliced cleanly and precisely.

Types of Blades

This metal-cutting saw typically takes either an abrasive disc blade or a cold saw blade (Carbide Blades).

Abrasive Blades

The metal is left extremely hot after being sliced because of the large number of sparks produced. It is not recommended for use with aluminum or other soft metals due to the high friction blades. Unlike a cold saw, which dulls with use, this type of blade's coating makes it resistant to wear even after multiple uses. The number of revolutions per minute (RPM) at which the blades spin is 3800.

The benefits of them are that they are easy to transport, inexpensive, and ideal for novices and enthusiasts.

Disadvantages: Cutting metal is sluggish and produces sparks. Minimal burrs and a sizzling afterglow are all that remain on the sliced surfaces.

Cold Saw Blades

As a result, the metal is safe to touch immediately after being cut because there were fewer or none at all. The metal-toothed blades it employs slice through the material much more quickly than their abrasive counterparts. Strong and robust, these blades make short work of metal stock and pipes, allowing for considerably cleaner slicing and chopping.

Advantages include a quick, precise, and burr-free metal inset cut. There will be no sparks or residual heat on the surface.

The blade is heavier and more expensive than others, which are also drawbacks.

Blade Tooth Count

The teeth of the blade are engineered to disperse heat and maintain a cool cutting edge and work piece. To ensure a smooth, precise, and burr-free cut, metal-cutting blades typically have between sixty and one hundred teeth per inch.

There are typically between 24 and 72 individual teeth on a carbide-tipped blade in a standard configuration. By adjusting the length and depth of the cut, the user may make cleaner cuts in less time. It allows the user a wide range of cutting options with minimal effort. You can get a good thousand uses out of them before having to replace them.

The stainless steel or long-lasting composite, like aluminum oxide, used to craft the blades' sharp teeth ensures that they will last a long time. They have a protective covering that lessens the number of potentially lethal sparks produced during construction.

If you want to save time and effort, as well as make sure the job gets done right, picking the right blade TPI is crucial.

Blade Size

Depending on the thickness of the metal you plan to chop, a different sized blade will be necessary. Consequently, while cutting metal bars of varying diameters, it is essential to use a blade of the appropriate size. The blade length will often be between 7 and 14 inches.

A diameter of 12 inches or less is adequate for most commonplace or personal usage.

A blade length of 14 inches or greater is recommended for usage in industrial settings.

For the most part, a 7-inch blade will do the job nicely.

If you're a hobbyist or do-it-yourselfer, you should get a blade that's at least 12 inches long.

Blade Rotation Speed

Since metal is a tougher material, it is best to utilize a slower cutting speed in order to achieve a clean, precise cut without risking injury to yourself or the worker. Blade speed is quantified in RPM, or rotations per minute (RPM) It is generally accepted that operating at a slower speed yields better results and increases the likelihood that the procedure will be completed without incident.

When cutting aluminum or other soft metals, use a speed that is higher than 3000 RPM (revolutions per minute), but don't go higher than 3500 RPM.

The optimal cutting speed for Haber metals is below 3000 RPM.

If you're cutting using carbide blades, you'll need a tool that can produce at least 1300 revolutions per minute (RPM).

Select a machine with a minimum RPM of 3000 if you plan on using an abrasive disc blade to cut the metal.

Angled Cuts and Fence Adjustment 

The blade of a chop saw oscillates up and down, hence the name. The blade cannot be turned or tilted like a miter saw used for carpentry. The workpiece is instead fastened against a revolving fence set to the desired angle.

It is common practice to utilize portable band saws for cutting rebar and piping. They are capable of cutting at any angle in theory, but due to their freestyle approach, precision is sometimes compromised. Depending on the design, this saw can be very adaptable in the workshop, whether it rises and falls like a chop saw or rests on a flat table from which the material to be cut is fed.

Motor Power and Source

Models intended for use in a workshop typically include 15A (amps) motors because that is the maximum current that can be drawn from a regular electrical socket. Saws with a 10 amp-hour motor are common in the portable kind; they are less powerful than their 15 amp-hour counterparts, but nevertheless produce satisfactory results. Heavy-duty variants often have a horsepower rating instead of an amp-hour rating, and they may need a separate circuit to function.

When describing the power output of a cordless metal-cutting saw, volts (V) are used instead of amps to represent the battery capacity. Powerful 36-volt tools are now on the market, with smaller, lighter 12-volt models also available.

Vise Adjustment and Blade Change

Band saws and chop saws typically used in workshops come equipped with a vise to firmly clamp the material being cut. Most only have one jaw that shuts against the fence, as opposed to the two jaws of a normal vice. Its maximum workpiece size is determined by how far the jaw can open. Many of these saws also feature quick-release mechanisms.

Chop saws typically contain a mechanism to halt rotation while the main nut is removed and a new blade is attached, making blade changes simple. Setting up a band saw is a little more work than usual because of the need to adjust the blade tension and tracking, but it is still a simple process.

Dust Collection System

It's possible that not all saws will have a dust collection system or port, but it's still something to look for. Our metalworkers and woodworkers found that using tools with a dust system cut down on cleanup time, and the same is true for you: your work area and line of sight will be kept spotless at all times.

Most people don't know this, but if you keep your cutting metal saw clean, dust and dirt are less likely to accumulate in its nooks and crannies and shorten its lifespan.

Spark Deflector

When cutting metal, it's common knowledge that abrasive saw blades will produce a lot of sparks. When equipped with a spark deflector, however, your saw can protect you and others around you from the flying debris. These upgrades are great tools to have on a metal saw.

Laser Guide

When making straight cuts, a miter saw, table saw, or circular saw will use the fence as a guide, but a metal saw will typically use a laser guide.

It's not required for everyone to use the laser guide, but it is essential for those who need to make extremely exact cuts. A laser light that directs your saw blade along a predetermined path is the essence of the laser guide. You can always expect precise cuts if you just follow the line.

You can make cuts by eye, but the results won't be consistent.

Safety Features

When the blade is in use or not, the safety features remain in effect. To safely remove metal scraps, a spindle lock can be used to secure the chuck of a metal saw.

Protecting your fingers from the sharp edge of a knife is another important application for blade guards. If a blade guard is absolutely necessary, our team wants to urge readers to keep an eye out for one that is see-through. One step better would be to search for a knife with a retractable blade guard.

Warranty

Pick a name-brand, high-quality power tool with the knowledge that you will be covered by a longer warranty. Since it's a one-time expense with long-term benefits. Don't forget to do a thorough evaluation of the tool's warranty policy before buying. The majority of these saws for cutting metal have a three-year guarantee.
