Choosing the Right Blade
When it comes to cutting metal with a scroll saw, selecting the right blade is crucial for achieving clean and accurate cuts. There are a few factors to consider when choosing a blade for metal cutting:
1. Blade Material
The material of the blade plays a significant role in its cutting performance. For cutting metal, it’s best to opt for blades made from hardened steel or high-speed steel (HSS). These types of blades are designed to withstand the rigors of cutting through various metals without dulling quickly.
2. Blade Teeth Per Inch (TPI)
The number of teeth per inch (TPI) determines the blade’s aggressiveness and the type of cuts it can make. When it comes to cutting metal, blades with a lower TPI are generally more effective. A blade with 18 to 24 TPI is ideal for cutting through thin sheets of metal, while a blade with 14 to 18 TPI can handle thicker materials.
Keep in mind that too high of a TPI may cause the blade to clog or overheat, leading to poor cutting performance and premature blade wear.
3. Blade Thickness
The thickness of the blade also affects its performance when cutting metal. Thicker blades offer more stability and are less prone to bending or breaking while cutting through tougher metals. However, thicker blades may create wider kerfs, resulting in more material wastage.
On the other hand, thinner blades produce narrower kerfs, allowing for more precise cuts and less wastage. They are suitable for cutting thinner metals or intricate designs.
It’s important to consider the thickness of the metal you’ll be cutting and select a blade that matches it for optimal results.
By considering these factors and choosing the right blade for your specific metal cutting needs, you can ensure clean, accurate cuts and maximize the lifespan of your scroll saw blades.
