What is a Metal Cutting Circular Saw?

A metal cutting circular saw is a type of power saw that includes a circular blade which revolves in order to cut metal. It has a handle that has an on and off trigger switch and some type of arbor nut to hold the blade in place. This type of saw is also designed with guards which protect you from touching the spinning blade.

Some people find that using a regular circular saw with a metal cutting blade also works in cutting metal. You can find lots of 7 ¼ – inch metal cutting blades from plenty of manufacturers, that would fit a traditional circular saw and slap it on. However, metal cutting circular saws are specially designed to handle not just a few but different types of metals.

Note: If you are a left handed person, check this article out for a detailed explanation about left handed circular saws.

How Does It Work?

Abrasive Blades Spark
Key Note: Saws with abrasive blades create sparks during cutting process. Choose a saw withcold-saw blade instead for efficient metal cutting.

A metal cutting circular saw works almost the same as a regular circular saw but there are a few small differences that matter a lot. Just like a regular circular saw, the metal cutting models have circular blade and when you activate the machine, the blade would turn to cut the metal. You activate the switch located on the handle to turn it on.

Compared to a metal chop saw, you need to move the saw thoroughly in order to cut the metal. Likewise, you can also cut metal in various angles.

Compared to a wood cutting circular saw, metal cutting saws operate with significantly lower speeds. This matters a lot because if the saw operates in a speed as high as a wood cutting circular saw, it exceeds the recommended cutting speed for metals. You will not get results that are as precise and as clean if you use a regular saw instead of a metal cutting one. Also, this type of saw has a blade designed for metal cutting.

Saw Parts

Metal cutting circular saw blade
Metal cutting circular saw blade – no sparks allowed!

A metal cutting saw consists of a number of parts including the blade and the handle.

The motor housing protects the motor that gets the blade running and the motor is usually on top of the blade. There is the handle set which lets you grip the saw with your hand and it’s best when it is ergonomically designed so that it doesn’t hurt your hand while you work. The on and off switch or trigger is usually on the handle as well.

The blade guard covers the blade when the circular saw is not being used and it retracts when you activate the machine to use the blade. It also has a foot plate or shoe which allows the saw to remain steady against the piece you are working on. The depth adjustment allows you to adjust the cut to different thicknesses.

You may also find a lock off lever which prevents the saw from accidentally turning on. Depending on the model, it may include the cord to plug the unit with unless it is a cordless saw.

What to Look for Before Buying a Metal Cutting Circular Saw?

If it’s your first time to buy a metal cutting circular saw, here are some important things to consider.

Weight

It is important that your metal cutting circular saw is light enough for you to operate. If the saw is too heavy, you may have difficulty in balancing it in your hand as you cut through the metal and it will create uneven cuts and edges. A lightweight saw also prevents accidents. A good weight for a metal cutting saw is about 13 lbs. but some models may be a bit lighter like the Makita 4131 which only weighs 10.6 lbs.

There are also more compact units available but of course, they are suitable for smaller projects. Choosing the weight of your metal cutting saw would depend on the type of projects that you would like to work on. A lighter saw would make it easy to focus the blade and some models allow for one hand operations.

Grip

The grip on the handle must be ergonomically designed not just for your comfort but for precision and safety. Look at the shape of the grip and see if it is contoured to fit the grip of your hand. The material also matters. It should not easily slip your grip or be too rough so it does not hurt you while working.

Blade

The most important thing to consider when choosing a metal cutting circular saw is the blade. The right size of blade depends on your needs and preferences and the type of projects you would be working on. It should be easy to clean and should require less sharpening over time.

Some blades are more advanced than others. You can find blades that are more versatile because they can cut through a variety of materials like wood and plastic. If you work on a lot of projects and not just metal-cutting, this type of blade may be more suitable for you. Other blades are specially designed to cut through tiles and stones. So, consider the materials that you use.

No matter how durable the blade is, you would still be required to change it at some point so check if it is easy to take out the blade and replace it. The accuracy of the blade is also crucial because it would determine the precision of your cuts.

Motor Power Capacity

For your circular saw to cut metal with prescription, it needs to have higher amps and volts which give it more cutting power, and more torque. The ideal RPM should be around 2,700 – 3,900 because higher than that would mean the blades would turn too fast and that reduces the precision in cutting metal. Lower than that and it may not cut through at all.

As for multipurpose metal cutting circular saws, the RPM may only be ideal for metal. That means you would just have to adjust your own speed when cutting. When cutting through wood with a multipurpose blade, work slower to avoid chips on the wood.

Versatility

If you would be working on projects that involve cutting various types of metals, your metal cutting circular saw blade should be versatile enough to cut those varieties. Some models may have limited cutting capacities which prevents you from cutting thicker metals.

Safety Features

Check for safety features such as a lock off lever which protects the saw from accidentally being turned on when not in use. The motor housing should be made of high quality materials to prevent the unit from overheating. You should also look at the blade guards and check how efficient they are so that the blades are secured when not in use.

Brand

There are a variety of brands or manufacturers of metal cutting saw blades. Trusted brands include Makita and Milwaukee but other brands also offer quality models. Choose a brand based on the company’s reputation in quality and warranty and compare prices to see which one gives you the best value for your money.

It’s good to read customer reviews so you can have a better idea of which brands produce the best products.

Price and Warranty

The average price of a full-featured metal cutting saw blade ranges from $250 to $350 but it doesn’t mean that you won’t find more affordable ones that also offer quality results. You can find some models at about $80 to $150. When considering the price of the unit, think about how often you would be using it and how long you want it to last.

The higher priced models usually include better warranty which makes them a good investment in the long run. If your profession requires the equipment, it is a wise decision to invest in a more durable model even if it means spending an extra $100.
