What is the proper procedure for replacing the blade on a table saw?

The correct procedure for replacing the blade on a table saw involves ensuring that the hole in the blade is the same size as the shaft of the saw. This alignment is crucial because it ensures a secure fit, allowing the blade to rotate smoothly and safely at high speeds during operation. If the hole in the blade does not match the size of the shaft, it can lead to improper installation, causing vibration, reduced cutting efficiency, or even dangerous situations if the blade were to detach during use.

The sizes must match precisely for stability, ensuring that the blade does not wobble or become loose while in motion. This compatibility supports both effective cutting performance and the safety of the user.
