1. Skip Tooth Blades
Skip tooth blades are widely used for general-purpose cutting in wood. They have large gaps between the teeth, which help to clear the sawdust quickly, preventing the blade from getting clogged.
2. Regular Tooth Blades
Regular tooth blades are similar to skip tooth blades but have smaller gaps between the teeth. They provide smoother cuts and are suitable for cutting softer woods with less risk of tear-out.
3. Double Tooth Blades
Double tooth blades have two teeth next to each other, followed by a larger space. They are commonly used for cutting thicker woods and can remove material more efficiently.
4. Spiral Blades
Spiral blades have teeth all around the blade, which allows cutting in any direction without the need to rotate the workpiece. They are great for making intricate cuts, curves, and patterns.
5. Crown Tooth Blades
Crown tooth blades have teeth that alternate between facing upwards and downwards. They provide smoother cuts and are ideal for cutting materials that are prone to chipping, such as acrylic or plastic.
Other specialized blades, such as metal-cutting blades, ultra-thin blades, and reverse-tooth blades, are also available for specific applications. It is important to choose the right blade for your project to achieve the desired results.
Choosing the right blade for your project
When using a scroll saw, it is important to choose the right blade for your project. The blade you use will determine the accuracy and quality of your cuts. Here are some factors to consider when selecting a blade:
1. Blade Type
There are several types of blades available for scroll saws, each with its own specific use. The most common blade types are:
