I can use your collective wisdom here gang. I am going to upgrade my miter saw with a slider. I like the 12” for greater cutting depth/width, but have heard the 12” blade deflects too much, hurting accuracy. So, my question is, get a 10” or a 12”?

Looking forward to your experiences..

I have the 12” DeWalt and love it. I don’t use it for cutting 45’s for my boxes but for cross cuts at 90 or angles that close is close enough it’s great.

I have the Dewalt 12” slider. I’ve never had any trouble with accurate cuts at any angle. I’ve used it with success at 45 degrees for boxes with no trouble. I’d say go for it.

10” does have a greater chance of deflection and vibration but the 12” blades have not caused me any problems as long as the blades are nice and sharp. When the blades start dulling I’ll see that reflected in the cuts sooner than I will with the 10”. It’s not really good practice to cut with dull blades anyhow so that’s a minor issue.

My preference is a 10” due to the inherently more stable blade and because I don’t have much use for the extra depth afforded by the 12” anyhow. Not even a Kapex can beat the tablesaw and a sled for perfect miters so wide cuts are done on the tablesaw. Since I learned to use Sketchup to calculate cuts I even do a lot of compound miters on the tablesaw.

I’d go with the 12” if I needed the capacity otherwise I’d stick with the 10”.

I have the 12” bosch chop saw, with forrest blade. Love it, I made zero clearance tables for it, on small parts they help me control the work piece.

I just have never set up my SCMS do do the 45s I get such good reslutes with the tablesaw and sled that I just use it all the time. I must say that the DeWalt was accurate right out of the box especially once I put a good blade on it. I’ll have to give it a try. It would be much easier to set up.

I’ve done tons of 45’s with my Dewalt, if you use a backer board gives you no tear out. It’s a great saw.

I have had a 12” DeWalt since 2000 and it works well for me. I bought it originally for building decks. When I need to replace it I think I will go for a 10”

I like my 10” CMS, but it’s about 14 or 15 years old and will probably upgrade to a SCMS. I think I will stay with 10”, but be sure the motor is mounted such that I can cut 4X stock. I like the Mikita with the hypoid drive and the double slide using 6 linear bearings.

I have the Dewalt 12” slider with a Forrest Chopmaster blade and it cuts an edge that is accurate and like glass. Dust collection sucks though.

I suppose it all depends on what it is you are going to be using for. My good old Hitachi 8.5” slide compund has trimmed houses with BIG crown moulding. Built buildings where I can 45/45 a 2×6 for rafter cuts. What ever you buy be sure you get a NEGATIVE HOOK ANGLE blade for finish work. You won’t regret it.

I have the Bosch 4410 10” SCMS and it cuts perfectly accurate, even with the stock Chinese blade.
When I bought the saw, I set aside the whole day to set it up. As it turns out, it only took me about an hour. The saw was perfectly aligned when I got it!

I’ve never really found myself needing the full capacity that a 12” has to offer. The only time was when I was refinishing my shop and needed to cut a couple of 16” shelves to length. I just set up the stop and flipped it over to finish the cut.

I took a job installs some 5 1/2” crown and had to rent a 12 inch saw. With that experience I was (as always) on the look out for a larger saw. I saw a 12 inch Bosch slider at a garage sale and I bought it. The previous owner had trimmed out his own house and was ready to get it out of his way. I brought it home and checked it out to see if it was square and the angles were accurate. You never know what the last guy did to it in many cases. I like it and use it often but it is probably no better if as good as the Craftsman radial arm saw that my son bought for $50 last week. It appears to be circa 1980.

10” Bosch. Had two of ‘em. It’s about time to replace this one-starting to get a little(read thousands) sloppy after 9 years. Looked at the 12” but doesn’t offer any greater crosscut capacity than the 10”. When I replace will probably get another Bosch. I like the way the detents are setup.

I have the 10” Dewalt Slider. It has all the capacity i need for trimming and laminate floors. I dont ever use it for anything thicker then 1x lumber and never needed more width cutting then the 10” provides. Has been a perfect saw paired with different Freud blades to match the job….. My dad, who does custom stair, has the 12” Dewalt Slider and no issues with it. he does need the wider cutting ability.
