Hello there, I'm an expert in woodworking and power tools. When it comes to choosing the right jigsaw blade for cutting wood, there are several factors to consider, including the type of wood you're cutting, the precision required for your cut, and the durability of the blade. Let's delve into the details.

Firstly, it's important to understand the different types of jigsaw blades available for wood cutting.
Jigsaw blades are designed with various teeth configurations and materials to suit different cutting tasks. Here are some of the key types:


1. T-Shank Jig Saw Blades: These are a popular choice for woodworkers due to their versatility and the wide range of available blade types. They fit most jigsaws and offer a secure grip.


2. Universal T-Shank Blades: These blades are compatible with a variety of jigsaw models and are suitable for a range of cutting tasks.


3. Segmented Blades: These blades have a flat cutting edge which is ideal for making straight and precise cuts.


4. Bi-Metal Blades: Made from a combination of high-speed steel and a durable backing material, these blades are designed for durability and longevity.


5. Reverse Tooth Blades: These blades have teeth that are angled in the opposite direction of the cutting motion, which helps to reduce the amount of splintering on the top side of the cut.

Now, let's look at the specific types of wood cutting jigsaw blades mentioned in your reference:

- T101B3: This blade is designed for clean cuts in wood. It's suitable for general wood cutting tasks and is likely to have a standard tooth configuration that provides a good balance between speed and cleanness of cut.

- T101BF: This blade is specifically designed for hardwood. It likely has features that enhance its durability and ability to make clean, straight cuts in dense materials.

- T101BR: This is a reverse tooth blade, which is excellent for producing splinter-free cuts on the top surface of the wood. It's particularly useful for projects where the finish quality of the cut is important.

- T101BR100: Similar to the T101BR, this blade also features a reverse tooth design for splinter-free cuts. The "100" could indicate a specific size or additional feature that sets it apart from the T101BR.

When choosing a blade, consider the following:

- Wood Type: Softwoods versus hardwoods will require different blade designs. Hardwoods are denser and may require more robust blades.

- Cutting Precision: If you need a very precise cut, look for blades with finer teeth.

- Cutting Speed: Some blades are designed for faster cutting, which can be useful for larger projects but may sacrifice some precision.

- Durability: Bi-metal blades are generally more durable and can withstand the rigors of cutting harder materials.

- Splinter-Free Cutting: For a clean finish, consider blades with reverse tooth design.

- Blade Size: The size of the blade (measured by the length of the blade body) will affect the depth of cut and visibility of the line you're following.

- Tooth Count and Pitch: The number of teeth and the distance between them (pitch) will affect the smoothness of the cut and the speed of cutting.

In summary, the right jigsaw blade for cutting wood depends on the specific requirements of your project. Consider the type of wood, the desired precision, and the blade's durability when making your selection. The blades you've mentioned, such as the T101B3, T101BF, T101BR, and T101BR100, each offer unique benefits for different types of wood and cutting needs.
