I have a 10 inch Ryobi compound miter saw. I am getting alot of tearout from the stock blade. The saw hasn’t been used all that much. My question is can I change the stock blade for a fine tooth blade? or is there a certain type of blade that I need to get?

Stock blades are notoriously poor. A good blade should improve the cut a lot. What to get depends on what you’ll be cutting and the finish you want. Generally 60T to 80T will do well. Assuming you start with a high quality blade (don’t bother with anything else), more teeth tends to mean a cleaner cut if all other parameters are equal (they’re not usually), but more teeth also means a more resistance to the saw, more strain, and a slower cut, so don’t think more teeth is automatically a free lunch but is a good start. You may hear that you need a low to negative hook angle for a miter saw blade….not true with a standard CMS, but true of a slider. Still, it’s best to stay with a moderate to low hook angle of roughly 10° or less, and avoid the 20° hook angles intended for general purpose and ripping blades.

The Infinity 010-060 60T Hi-ATB blade is one of my favorites (~ $70). The Hi-ATB grind has the lowest amount of tearout of all grinds, but can also wear a bit faster…an excellent choice for fine finishing cuts in hardwoods, a poor choice for laminate flooring and non-ferrous metals. 5° hook, made in Italy, world class blade. The Forrest WWI is a very similar blade but tends to cost quite a bit more. Their 80T 010-080, and 010-280 are also an excellent choice and an even cleaner cut due to having more teeth, but I haven’t tried these personally.

The Freud LU79 (TK), LU80 Hi-ATB blades, and LU85 ATB blade are all excellent choices as well. They also offer the LU91 60T specifically for sliders, but is still a nice choice for a CMS. For less money you can get into a Freud Diablo thin kerf….not quite to the same level but still very good.

For less money yet, Holbren’s got a great deal on the Oshlun line. 80T, ATB grind, large C3 micrograin carbide, copper silencers and are surprisingly well made and good performers for ~ $30.

Rick, I have replaced all my stock blades with Forrest blades. I have found that blades supplied with a tool are generally not the best blades to use. If they can cut corners somewhere it seems that the manufacturers are putting blades of less than sterling quality on their tools because they are cheaper. Certainly replacing it with a quality blade should improve your cut.

Another option you can do is to replace the insert in your saw and turn it into a zero clearance insert similar to replacing the throat plate in your table saw. This will help improve the quality of your cuts as well. The biggest problem of course is that doing bevel cutting will widen the kerf. But 90 percent of the cuts I make on my saw are done with the blade at 90 degrees.

I don’t have any specific blade recommendations (still using the stock dewalt blade that came with my saw)

Here’s how I solved my tearout problem:
1) Replaced the plastic insert in the table with a zero-clearance insert I made from 1/4” MDF
2) Double stick taped another piece of MDF on the fence

Not only has this eliminated tearout from my stock blade, but it’s amazingly easy to line up pieces without any lasers or anything.

I have an older lower end Delta and found great improvement with going to a Diablo blade. Since it is mainly for 2×4 and getting boards to rough length I didn’t go beyond that grade.

Also, I found that my saw was coming down on very slight angle causing fuzz and tearout mostly on one side of the cut. Check to see if your issue is on both sides of the board you cut. If the tearout is on one side more than the other, check the blade alignment. I forget how I adjusted mine, but the cuts became much cleaner. After the alignment I just had to kiss the edge with a sanding block.

The right blade can make all of the difference in the world.

I had a lot of tear-out with my miter saw … I picked up a Freud 80-tooth thing kerf cut-off blade on sale ($48) at a local machine shop. Now my miter saw cuts clean and true.

The blade is the thing…as stated above….I only use forrest blades for fine work…..for junk ripping…and cutting…I switch back to the stock blades. For the price I haven’t seen anything cut as well…but don’t waste them if you are just cutting dimensional wood….if I worry about tear out on the crappy blades…I just run a piece of tape around where the cut is….or I tape on a piece of sacrifice scrap to the piece before cutting…works everytime.

I have found that some times the cheaper blades have a good carbide, but they are not sharpened properly or at all. I have taken what seems to be a bad blade and sharpen it with a diamond sharpener and been amazed on difference of the cuts. From the factory normally you will find a finer quality blade have a better cut out of the package than a cheap one. The expensive name brand blades believe they have one shot in making the customer happy. The big difference comes in how long the the blade with hold its edge. Cheap carbides will not last long, high quality carbides will last a long time especially on hard wood.
You may also want to put a stabilizer on your saw with install your blade. This keeps the vibration & flexing down on the blade. There are single and double stabilizers. I own both, but I have the double on my table saw and it helps out mostly on long rips and cross cuts. For finer cuts the more teeth the better the cross cut on any saw.
If you still get some tear out, you add a thin strip on the back side to give support to the good board.
Hope this helps you.

I replaced the stock blade in my Crapsman 10” SCMS some time ago. I went with a Freud Avanti 80 tooth. I dont remember if its a neg hook blade or not. I do get very acceptable cuts in all materials and it was not an overly expensive blade. I believe I paid somewhere around $50 at the big box store.
