Bore size (arbor hole diameter) ensures the blade fits securely on your saw. The most common sizes in this category are 5/8" and 1/2", with some blades offering a diamond knockout for additional compatibility. Choosing the correct bore size prevents wobbling and ensures safe, accurate cuts when using contractor saw blades. For example, the Timberline 175-24C comes with a 5/8" bore and diamond knockout for universal fit, and the Timberline 150-400 features a 1/2" bore for smaller saws. The availability of multiple bore sizes and diamond knockouts means you can find a blade that will fit your machine perfectly.
