In reality, cold saw blade during the grinding process, and they transfer heat and energy to the chip. It allows them to remain cold. Thus the name “cold saw blades.” As a beginner or intermediate with a cold saw, you wonder how to get maximum results with the cold saw blades. You also wonder how long you need to use it before sharpening the cold saw blades. It is why we set up this article. To hint you on how to use a new cold saw blades.

1.Cold Saw Blade-Apply Correctly:
When you buy a new cold saw , use it appropriately. It allows you to prevent it from wearing down prematurely. Solid HSS cold saw blades specifically made to cut stainless steel. TCT cold saw blades are the best use with metals. However, Ferrous metals are harder than non-ferrous metals, and this allows you to use TCT ferrous metal cutting cold saw blade to cut non-ferrous metals.
However, you can’t use non-ferrous metal cutting cold saw for ferrous metals. It will wear it down, making your new cold saw blades useless early. Different cold saw have different recommended operating speeds for different materials. You must consider this before using your cold saw for cutting metals or stainless steel. Therefore, choose the proper cold saw blades for maximum performance and longevity.

2. Cold Saw Blade-Allow the Blade to Do the Work:
When you use a cold saw , it is only proper you know the appropriate force/pressure to exert. It is about the power tool you are using. When you don’t force the cold saw into metals and stainless steel, you allow it to do its job. It brings so much difference in the lifespan of the blade as against when you force it. Excess force or pressure does not make a better cut. It only adds excess stress to your cold saw. The teeth might break, or the blade might crack with this. The best way to avoid this is to ensure you follow manufacturer recommendations.
It allows you to understand its cutting speed, feed rates, and RPM. This understanding allows you to maximize your cold saw blade performance. It is why you must let the cold saw blade do its work without forcing it. Let the cold saw blade rotate at full speed before you start cutting. Do not add pressure to the blade as it cut through. All you need to do is pull the power saw forward. Do not overfeed the blade, and holding the saw helps you use the cold saw blade better.
When you let the cold saw blades dictate the cutting rate and set the chip load, you will spend less effort cutting. You would also have good finish quality. Tight clamping is also another way to let your cold saw blades do the work. Tightly clamp your metals/stainless steel in the vise, so it does not move during cutting. If it moves during the cutting, the cold saw blade is likely to break.
3.Cold Saw Blade-Use an Automatic Saw:
If you can afford it, you should use an automatic or semiautomatic power saw with your cold saw blade. Compare to manual saw, and automatic power saw increases the lifespan of your cold cut saw blade by over 25%. It does this by reducing the time for cutting metals or stainless steel. With less cut, your cold saw blade does not wear easily.
Also, as a beginner, it is in your best interest to use an automatic saw with your cold saw blades. They both work together to transfer the heat energy to the chip more efficiently than manual saw. It is also easy to match your cold saw blade horsepower, shaft speed to the automatic power saw. By using the same horsepower, you cut faster. It is also important you match the blade shaft speed. If not, blade warpage, wobbling, and excessive wear would occur.

4.Regulate the Speed of Your Cold Saw Blade:
When you attach a cold saw blades to a power saw with two (2) speeds, regulate according to the material you are cutting. When cutting stainless steel, use a much lower speed. When cutting metals, use a much higher speed. The speed list could be surface feet per minute (SFPM) or the regular RPM. Sticking to this speed will increase blade life and cutting ability. Most of the power saws have just two types of speed (high and low). It would make it easier for you to regulate it according to metal and stainless steel. It ensures you get a lot from your cold saw blades. Doing this ensures that you tightly bind the blade to the main spindle. You also put the bolt holes against the bolt in the proper direction.
5.Cold Saw Blade-Clean and Lubricate:
Cutting metal and stainless steel with cold saw blades, and deposits stick to it. You must clean before it makes the blade edges blunt. When you don’t clean it, deposits harden and form a rough surface on the sides of the cold saw blade. When you cut with these deposits, they cause friction. It goes on to affect the quality of cuts of your metals and stainless steel. To avoid this, you need to clean the cold saw blade regularly. Before you start cleaning, ensure to detach the cold saw blades from the power saw. Clean properly with popular cleaning spray.
Spray on to both sides of the cold saw blades and allow it to sit for some minutes. Wipe it off after. It should remove the deposits from your cold saw blades and leave it in a good cutting condition once more. After cleaning, apply lubricant to it. It prevents the metal of the blade from rusting. Lubrication also helps your cold saw blade make better cuts. It is why every time you clean, also ensure to lubricate. Be familiar with the warning signs of poor blade performance and excessive wear. It helps you to know when to clean, lubricate, sharpen your cold saw blade, or discard it.

6.Sharpening Your Cold Saw Blade:
When you use your cold saw to a point where cleaning and lubricating no longer do the trick, you need to sharpen it. Sharpening is a vital part of using a cold saw blades. It is because when done regularly, it improves the cutting efficiency of your blade and improves its lifespan. However, when you decide to sharpen your cold saw blades, ensure to do it well. Poor sharpening causes more damage and leads to inconsistent cutting. You need to consider the blade geometry and tolerances when sharpening. You could give it out to companies rendering sharpening services. They will sharpen it and get it to you in good condition. You could also sharpen it yourself.
To do this, you need to get an appropriate cold saw blades sharpener/filer. Detach it from the power saw when you want to sharpen the blade. Clamp it in between two planks of wood. Raise part of the saw blade and place the sharpener at an angle where the cutting teeth of the blade are visible. Pull it back and forth. Repeat until all the teeth have had their turn. You will come out with a cold saw with shiny edges again.

7.Take Safety Measures:
The cold saw is as dangerous as another saw blades when you handle carelessly. To avoid unnecessary injuries and damage to materials, always ensure some vital safety Precautions. Wear safety masks and gloves. It is to protect your face and hands from hot flying chips. Checking the clamp while using the cold saw blades is also important.
It helps avoid serious injuries that could happen if the clamp is not tight. The cold saw blades should also put into good storing conditions. During operation, always direct the cold saw blades away from your body. Strive to maintain a good and comfortable distance always.
