High RPM: Rotations per minute are an important consideration when you are looking to buy the ideal portable table saw. It ensures that you can cut the wood/material a lot more efficiently and accurately. It also means that the thickness can be adjusted easily, and you can get a plank to the thickness that you would like. The high RPM also makes sure that the cut is relatively smooth and the rips do not show up in the form of uneven edges. On an average, most table saws have a 15 amps motor. It is the RPM that makes a big difference in performance. Anything above 4500 is fantastic.
A riving knife is a piece of metal that comes included with your new saw. It’s shaped like a surfboard fin. Sadly, not all models come with this crucial part. If you purchase a model without it, make sure you design one for yourself as soon as possible. The construction of this piece is not a big deal at all; you can cut the shape in a matter of minutes and install it. Its purpose is to prevent the wood and debris from getting caught in the back of the blade which consequently kicks back thus jeopardizing your safety.
