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.
