Depending on the material they are made of, parts of the circular saw can offer more or less endurance. The circular saw base plate is one of the materials that can be made out of different materials. A base plate shoe is a sheet of metal that can be made out of:
Each of them has both pros and cons, and even though they look very similar, there are lots of differences between them.
A steel base plate is the cheapest and heaviest. A steel base plate can be more easily bent if dropped but can be easily repaired. An aluminum base plate is usually lighter and thicker than a steel base plate. It will not bend but can crack. A magnesium base plate is the best as it is the lightest and strongest of the three types.
Here are my top picks for each base plate type:

What does the best type of base plate look like?
When buying a new circular saw, you should definitively pay attention to the base plate. Why?

Because the accuracy of the cuts mostly depends on the base plate, it is extremely important to find a quality one.
Don’t go for the cheapest one, as you will need to replace it very soon.
Believe it or not, the base plate shoe is the part of the saw that is most likely to broke. In order to prevent that, you will have to find a thick plate, with square edges.
Steel vs aluminum vs magnesium circular base plate shoes
In this section, you will learn the basics of each type of base plate, what makes them different and what are the pros and cons of each one.
Steel base plate
The cheapest way to make a base plate is using a steel. This type of base plate is the most flimsy and can bend easily if you drop the saw.
Then, I won’t drop the saw. I guess that is what most of you think right now. But no matter how careful you are, your circular saw will fall off your hand at one point. And regardless of the height, you drop it, the base plate would bend.
If it is a minor damage, you can repair it, but you need to be sure that the surface is completely flat, which is pretty difficult from my point of view. So, it is better to buy a new base plate as soon as possible. However, don’t even think of cutting with damaged base plate shoe, as you will end up with very poor cuts.
For example, if you have a rolled edge on your base plate and you are using a thin straightedge as a saw guide, the circular saw may slip over guide which will result with an inaccurate cut.

Aluminum base plate
This type of base plate is much better than the steel one. It is thicker, softer, and way more resistant to damage. Plus, the aluminum is a metal that weighs less than steel, so your saw will weigh less as well.
Most of the aluminum base plates are cast, and you should be happy to end up with one of these. However, some of them may be pressed just like the steel ones.
Aluminum base plates are more expensive, which is quite normal since they are better. They have crisp edges and one big downside – they cannot bend, but they can crack.
|thicker, softer||more expensive|
|resistant to damage||can crack|
Magnesium base plate
This type of base plate is the strongest and the lightest. If you ask anyone who works with a circular saw for a while, this would be the recommendation of a base plate shoe.
However, you will need to pay more for it, as it is the most expensive base plate. It has another disadvantage, as just as the aluminum one, it can crack too. Once the base plate is cracked, there is no other solution than buying a new base plate.

Bonus: fiber-reinforced plastic base plate
The fiber-reinforced plastic base plate is said to be the toughest and thickest of all plates. They are much more flexible, so they need to be really stiff in order to work as they should. However, I won’t include it in the comparison since almost every power tool manufacturer sticks to the metal ones.
