A cold saw is a useful tool for metalwork. The saw makes use of a circular saw blade that has several teeth along the outer rim to cut through metal. It is powered by an electric motor and also has a gear regulator. This allows you to control the speed as you work. A coolant delivery system within the machine discharges coolant to the blade while the machine is operational. This helps to keep both the blade and work piece cool. The saw can attain extremely high torque levels. Combined with the heavy nature of the tool and ultra sharp blade, this requires extreme caution as you work. Below is a guide on how to use the tool properly.

Step 1 – Position the Cold Saw

Place the machine close to a wall which will act as a safety screen. Flying bits of metal and debris are usually discharged while the machine is in use. Secure the machine onto the floor with fasteners. Make sure there is adequate space to enable comfortable access to the machine. Plug the cable into electrical outlet. If your work piece is large or heavy, you must use an extended bench to support it.

Step 2 – Check the Machine

Set the safety guards on the machine before you run it. This will help to protect you from the moving parts of the machine. Check the blade to ensure it is in good condition. If you spot any signs of damage, it is best to replace it.

Step 3 – Run a Test

Turn on the switch so that you can confirm if the rotation of the saw blade is clockwise. If rotation isn’t clockwise, ask an electrician to make the necessary adjustments. Press the “Emergency Stop Button” to confirm if it works.

Step 4 – Secure the Work Piece

Firmly clamp the metal to be cut in the machine vice. This is located underneath the blade. Check to see that the work piece is not against the blade before you run the machine.

Step 5 – Cutting

Turn on the machine and allow it to attain full speed. To move the blade, you must steadily depress the handle on the machine. Do not force the blade to cut the work piece as the blade may break. When firmly secured in place and set properly, the blade should be able to cut through the metal with ease. Vibrations or unusual noises while the machine is operational indicate it is not being handled properly. Use a stick to remove off cuts to prevent serious cuts to your hands. Do not attempt to remove off cuts while the blade is in motion.


  • Wear safety glasses to protect your eyes from flying chips of metal. You also need some form of protection for the ears due to the extremely high noise levels.
  • Avoid loose clothing and jewelry when at work as this can easily get caught in the machine. It is best to contain your hair if it is long.
  • A cold saw can produce extremely high noise levels.
  • Keep your hands away from the saw blade at all times to prevent serious cuts or amputation.
