Frequently Asked Questions (FAQs)
1. Can you cut stainless steel with a jigsaw?
Yes, it is possible to cut stainless steel with a jigsaw. To achieve a clean cut and prevent heat buildup, it is important to use the right jigsaw blade, apply minimal pressure, and set the cutting speed to slow. By following these guidelines, you can effectively cut through stainless steel without wasting jigsaw blades.
2. Which type of jigsaw blade offers the cleanest cut?
For clean cuts on wood or laminated material, a down-cutting blade is recommended. This type of blade has teeth angled downwards and cuts on the downstroke. On the other hand, a reversed-tooth blade, with teeth angled upwards, is used for cutting on the upstroke.
3. Why is stainless steel so hard to cut?
Stainless steel is difficult to cut due to its large plastic deformation during the cutting process. Austenitic stainless steel, in particular, has high elongation, which increases the cutting force required.
4. How many TPI do I need to cut stainless steel?
The number of teeth per inch (TPI) required to cut stainless steel depends on its thickness. For thinner metals like sheet metal, use 18-24 TPI bi-metal blades. Thicker metals such as steel pipe or angle irons require 14-18 TPI bi-metal blades. For cutting aluminum, an 8-10 TPI blade is recommended.
Metal-cutting jigsaw blades typically have a single row of teeth arranged in a small wave pattern from left to right. Look for blades with a TPI range of 21-24 for cutting metal. Additionally, blades manufactured with bi-metal construction offer enhanced durability.
6. Is it better to cut stainless steel fast or slow?
When cutting stainless steel, it is generally recommended to start slowly and monitor the temperature. Whether you're using a jigsaw or other cutting tools, it's important to take proper safety precautions when working with stainless steel.
7. Which saw blade makes the smoothest cut?
Saw blades with densely packed teeth make the smoothest cuts. However, these blades are typically limited to cutting hardwoods that are 1-1/2 inches thick or less. The close spacing of the teeth creates more friction, and the small gullets evacuate sawdust slowly.
