Thanks for your reply. Here is the scenario. I bought a 12" DeWalt miter saw with sliding for $399 and I bought 12" Dewalt without sliding for $389 with Dewalt heavy duty miter saw stand. And I bought both I did not open either yet. I am thinking about returning sliding one as I will have a table saw and I already purchased a circular saw as well. Your thoughts please!
I live in Atlanta metro area. Mostly for D.I.Y. My first project will be workbench and starting with easy beginner stuff first. Here is the scenario. I bought a 12" DeWalt miter saw with sliding for $399 and I bought 12" Dewalt without sliding for $389 with Dewalt heavy duty miter saw stand. And I bought both I did not open either yet. I am thinking about returning sliding one as I will have a table saw and I already purchased a circular saw as well. Your thoughts please!
Each situation is different. What works for me may not work for you and vice versa. Nobody wants to waste money, but some people have more financial constraints than others, which may factor into yes/no purchase decisions. Another factor is space for your tools.
It isn't only about the big power tools. You may also want smaller power tools like a drill/driver, a jigsaw, or a random orbital sander. You will need some kind of dust collection. (I get by with a shop vac.) You will also need marking/measuring tools (like a combination square), clamps, chisels, and many other accessories. You will need consumables like glue, sandpaper, and more. Safety equipment is critically important - dust masks, eye protection, and hearing protection. You need good lighting. All those costs add up.
Don't forget storage, organization, and working conditions. You need a place to keep everything where you can find them. You need sufficient shop space and good lighting to work with your tools. Tools take up space, but they also need additional space around the tools to use them.
Responding to Your Direct Questions:
I am not you. If you were my neighbor and friend who was definitely getting a table saw and has a circular saw, I would advise you:
Return the miter saws, and see what you can do with the table saw and circular saw. The more you do with less, the more you will know about which tools you will really need and what features you really want in the next tool. By then, you will have a much better idea of which miter saw you will want and why. Use the refund money for all the other things I described above.
If you are going to keep a miter saw no matter what, then I would advise you:
The one thing that the 12 inch miter saws can do over the table and circular saws is crosscutting a 4x4 in one pass. You can cut a 4x4 with a table saw or circular saw in two passes, but it takes more time to set it up for safe cuts, and getting a perfect clean cut is more difficult.
If it were me, I would choose the sliding miter saw, based on my experience with my spouse's non-sliding 10 inch miter saw. I flip boards to get wider cuts (not recommended for safety reasons), and perfect alignment is difficult.
