10 vs 12 Miter Saw – Full Comparison


We’re talking about electrical saws here, so they are quite heavy no matter what, but, of course, a 12-inch miter saw is much heavier than a 10-inch miter saw. Moreover, most of the time, the 12-inch miter saw will be mounted to your workspace; therefore, it will be stationary. While you can move a 10-inch miter saw  around when needed. Some opinions suggest that if you have the financial freedom to do this, you can keep the 12-inch it mounted in your workshop and keep the 10-inch for outside jobs, just pick it up, put it in your truck and get going.


12-inch miter saw blades are massive; therefore, the distribution of the teeth on it is wider, and this is a disadvantage. As 50 teeth on a bigger radius is worse than 50 teeth on a smaller radius. Also, the 10-inch miter saw can share it’s blade, sometimes, if you are in a rush, with a table saw, and it will work just fine. However, you can never ever do that to a 12-inch miter saw, that would only lead to disaster.

Kind of Work The Device Is Intended For

This is the main point that you should be thinking off and it can be a dealbreaker in many cases. If your work is mostly large scale projects with large boards above the standard 4×4, then you should just save your time and effort and get the 12-inch miter saw. But, if your work is more focused on details and small projects, perhaps some baseboards and windows; then you don’t need to waste your money on a 12-inch. The 10-inch will do just fine, and if you are cornered into a situation where you have to work with a bigger board once or twice, then you can follow the trick mentioned before, which is cutting from one side and flipping the board then cutting from the other.


Now, this is a very natural logical conclusion, a smaller blade with a smaller radius will spin much faster than the blade of a larger radius. That shows when you find the 10-inch miter saw spinning at 5000 RPM while the maximum of the 12-inch miter saw is 4000 RPM.


You must always know that durability of any device is mainly dependent on the use of it, so if you get a 12-inch miter and hardly use it a lot choosing to focus more on your 10-inch miter saw, then that is sure to tip the scales a little bit and vice-versa. But, let’s say you use both for the same amount of time. The 12-inch miter saw is bigger; it has a stronger motor, so cutting through materials is no big deal for, it doesn’t put a lot of effort into its work. Thus, the blade will remain pretty sharp for a long time. While with the 10-inch, you’re jumping from one board to the other, from one thickness to the next, blades are bound to dull much quicker.


However, one con of the 12-inch miter saw is that it has been found to be a little too light on the front side of the entire device. This means that sometimes it might lean backwards and if you’re not paying attention or if you have not bolted it down to your working-space at first. It could lead to some serious injury. Another thing is that when you are done with its, and you pull the blade up, the guard does not come down entirely to cover the blade. So, whenever you’re done with the 12-inch miter saw, you have to pull it up and keep your hands, your clothes and just about everything to yourself. Don’t come near the blade before you’ve unplugged the device and the blade has stopped rolling.

Overall Cost

Also, you are not just looking at the hefty price tag; you’re looking at the fact that it will suck in a lot of electricity in relation to the 10-inch, so you’re also looking at a bigger electricity bill. Maintenance also is not only expensive but not available everywhere for the 12-inch miter saws . It’s hard to find blades and spare parts; it’s hard to find people who are specialized in them. So, they can be quite expensive; however with the 10-inch miter saws you can just head to the hardware store nearest to you, and you’ll find a full range of blades plus everything you could want or need.
