Factors to consider when selecting a piercing saw:
When selecting a piercing saw for cutting sheet metal, there are several important factors to consider. These factors will ensure that you choose the right saw for the job and achieve the desired results.
1. Blade thickness:
The thickness of the blade plays a crucial role in determining the maximum thickness of sheet metal that can be cut. Thicker blades are generally more durable and can handle cutting through thicker metals. However, they may also require more effort and force to use. On the other hand, thinner blades are suitable for cutting thin metals but may be more prone to breaking or wearing out quickly. It is important to consider the intended use and the thickness of the metal to be cut when selecting the appropriate blade thickness.
2. Teeth per inch (TPI):
The number of teeth per inch is another important factor to consider. It determines the cutting speed and the quality of the cut. Blades with higher TPI produce smoother and finer cuts but may require more time and effort. Lower TPI blades are suitable for rougher cuts but may result in a rougher finish. Consider the desired cutting speed and the level of precision required when selecting the appropriate TPI for your piercing saw.
In addition to these two primary factors, it is also important to consider the material of the blade, the size and design of the saw frame, and the overall comfort and ergonomics of the saw. Taking these factors into account will ensure that you select a piercing saw that is both effective and comfortable to use.
Understanding the different types of blades:
The choice of blade is crucial when it comes to cutting sheet metal with a piercing saw. Different blades are designed for specific purposes and have varying characteristics that determine their suitability for certain thicknesses of sheet metal. Here are some common types of blades:
