Default Just a quick inquire

I bought a second hand DeWalt miter saw DWS780 in good shape but I would like to to change the blade.
Should I buy the original blade or another that you suggest. Price is an issue I'm on a pension

Stuart

Stuart for a mitre saw a negative or at least zero degree rake is a must. Getting into positive degree rake angles means risking hooking into the grain and lifting the board off the saw base and jamming it against the top housing as well as giving a very rough cut going cross grain. Full kerf saw blades will give a better cut. If you use a thin kerf blade I recommend using it with saw blade stiffeners. On a 45 * angle thin kerf blades can wander in the cut bouncing off hard summer grain and digging into soft spring grain. That results in a wavy cut.

Further to what Charles said, the blade manufacturer will (or should) have marked the blade for it's intended application.
I use CMT, not necessarily recommending them, just mentioning it because it makes for easy examples...

Industrial circular saw blades-Industrial sliding compound miter & radial circular saw blades-CMT tools

Industrial circular saw blades-ITK finish sliding compound miter circular saw blades-CMT tools
The whole line-up:

Stuart; I use CMT blades but I have been paying way less than what Amazon.ca is currently charging...it may have something to do with our devalued currency(?)...

Their blades are clearly marked for their intended applications.
I'm assuming Freud marks theirs in the same way?

Stuart,

If the saw has a blade, have you considered having it sharpened.

Well gentlemen I did some studying about 12 " saw blades and it takes some thought but it seems that the good brands are Diablo which is expensive CMT which is very expensive (DaninVan where would you get them at a lower price than Amazon) and Danman 1957 I live in Brossard and I don't know of any place to sharpen saw blades.
I'll have to go around tool places to see what they have,you can't see what they really have on line.
If there is anything you think of bring it here and I'll keep an eye on this thread. The blade in the saw is an exchange a blade EAB for short
Thank you guys
Stuart

Stuart you don’t want to focus just on the price. You want to focus on value. That includes how well it cuts and how long it lasts. If all you are using it for is cutting 2x4s than it’s not important but if you’re cutting mitres for picture frames a cheap blade that wobbles in the cut is a total waste of money and therefore poor value.
