One of the most important factors to consider is the material that you will be cutting. Jig saw blades are designed to cut different materials such as wood, metal, plastic, and ceramic. It is important to choose a blade that is specifically designed for the material you will be working with.
TPI (Teeth Per Inch)
The TPI, or teeth per inch, refers to the number of teeth on the blade. Blades with higher TPI are generally used for making finer cuts in materials such as wood. On the other hand, blades with lower TPI are more suitable for cutting thicker materials such as metal.
Blade Thickness
The thickness of the blade also plays a role in the type of cuts you can make. Thicker blades are more durable and can withstand higher cutting speeds and tougher materials. Thinner blades, on the other hand, are better suited for making intricate or curved cuts.
Blade Shank
The shank of the blade is the portion that attaches to the jigsaw. There are two common types of shanks: T-shank and U-shank. T-shank blades are more commonly used and are known for their tool-less blade changing systems. U-shank blades, on the other hand, require a screw to secure them in place.
Blade Coating
Some jig saw blades come with a coating, such as a carbide or diamond coating, to enhance their durability and cutting performance. These coated blades are more suitable for cutting harder materials like metal or ceramic.
By considering these factors, you can select the right jig saw blade for your specific cutting needs. It is important to choose the appropriate blade for the material and type of cut you will be making to ensure clean and precise results.
TPI and Teeth Configuration for Aluminium Cutting
When it comes to cutting aluminium with a jigsaw, the choice of blade is crucial for achieving clean and precise cuts. Two important factors to consider are the TPI (teeth per inch) and the teeth configuration of the blade.
The TPI refers to the number of teeth on the blade per inch of its length. For cutting aluminium, a lower TPI is generally recommended, as it allows for a higher tooth speed and reduces the risk of clogging. A blade with a TPI between 8 and 14 is often suitable for aluminium cutting.
In addition to the TPI, the teeth configuration of the blade can also affect the cutting performance. Different blade manufacturers offer blades with varying tooth shapes and patterns, such as wavy or progressive teeth.
