Cold Saw Tips: Cutting Speed and Feed Rate Cold Saw Tips: Cutting Speed and Feed Rate

Using a cold saw to make cuts in metal materials often produces a higher quality cut while significantly lowering the need for secondary finishing of the material. The term "cold saw" refers to electric powered saws, typically circular saws, that use special types of blades to cut metal.

Benefits of a Cold Saw

Typically when cutting metal both the material and the saw blade can become extremely hot, tarnishing the metal and potentially ruining any finish on it, as well as ruining a typical saw blade, which most commonly are designed for wood cutting. Too, the debris that is created using a traditional saw (piles of metal shards and splinters) are a hazard.

Blade Speed and Feed Rate

Blade speed and feed rate correlate with one another. Speed affects the rate at which the material that is being worked with can be cut, or fed through the saw. If the speed of the blade is too fast, it will result in a less than desirable cut in the material, and premature dulling of the saw blade. By reducing the blade speed, the saw blade is able to be best utilized with optimal placement of the blade's teeth, producing a higher quality cut. The feed rate is also enhanced due to the higher efficiency.
