A wider blade provides more stability and is suitable for resawing or making straight cuts through thick materials. On the other hand, a narrower blade is ideal for intricate and curved cuts.

2. Teeth Per Inch (TPI): The TPI of a bandsaw blade refers to the number of teeth present in one inch of the blade. Lower TPI blades are best for rough cuts and for cutting thick materials, while higher TPI blades are suitable for making fine cuts and cutting thin materials.

3. Blade Length: The blade length of a bandsaw is determined by the size of its wheels and the distance between them. It is important to choose a blade that fits properly on your bandsaw to ensure smooth operation and accurate cuts.

Blade Width

The width of the bandsaw blade plays a crucial role in determining the type of cuts you can make. A wider blade provides more stability and is ideal for straight cuts and resawing. For general-purpose cutting, a 1/2-inch or 3/4-inch blade is commonly used. These blades offer a good balance between stability and maneuverability. If you have a small bandsaw and plan to make intricate cuts or tight curves, a narrower blade in the range of 1/8-inch to 1/4-inch would be more suitable.

Keep in mind that wider blades require more power to drive through the material, so make sure your bandsaw is equipped with a motor that can handle the width you choose. Additionally, the width of the blade should also match the size of the bandsaw’s blade guides to ensure proper tracking and stability during cuts.

It’s worth noting that some bandsaws are designed to accommodate multiple blade widths by replacing the blade guides and adjusting the tension settings. This allows for more versatility and the ability to switch between different types of cuts.

Teeth Per Inch

The number of teeth per inch (TPI) on a bandsaw blade determines the type of cuts it is suitable for and the finish it produces. Blades with lower TPI, around 2-3, are used for rough cuts and resawing. They remove material quickly but leave a rougher surface. Higher TPI blades, in the range of 10-14, are best for making fine cuts and cutting thin materials. They produce a smoother finish but cut slower. For general-purpose cutting, a blade with a TPI of 6-8 is commonly used.

When choosing the TPI, consider the thickness of the material you will be cutting. Thicker materials require lower TPI blades to prevent the teeth from clogging, while thinner materials require higher TPI blades for cleaner cuts.

It’s important to note that some bandsaws allow for the installation of variable pitch blades. These blades have different TPI along their length, providing the benefits of both coarse and fine blades. Variable pitch blades are ideal for cutting a wide range of materials and achieving versatile results.

Blade Length

The blade length of a bandsaw is determined by the size of its wheels and the distance between them. It is crucial to choose a blade that is compatible with your bandsaw’s specifications to ensure smooth operation and accurate cuts. Most bandsaws have a specific range of blade lengths that they can accommodate.

To determine the correct blade length for your bandsaw, measure the distance between the center of the top wheel and the center of the bottom wheel. Alternatively, you can refer to your bandsaw’s manual or consult the manufacturer’s guidelines for the recommended blade length. Using a blade that is too long or too short can result in poor tracking, excessive vibration, and compromised cutting performance.

When purchasing a new bandsaw blade, ensure that it is the correct length for your bandsaw. If your bandsaw allows for blade tension adjustments, make sure to properly tension the blade according to the manufacturer’s recommendations for optimal performance and longevity.
