Can you sharpen carbide teeth?
Herein, can a carbide saw blade be sharpened?
You can sharpen steel-toothed circular saw blades yourself using a file. Carbide-tipped blades need to be taken to a professional sharpening service for two reasons: Carbide is so hard that you need a diamond wheel sharpener for it, and sharpening carbide blades is so complicated that you can easily ruin the blade.
Herein, are saw blades worth sharpening?
Sharp blades are always worth having. I pay about 30% of what a new blade would cost to have them sharpened. They can be sharpened again and again and they're like new when I get them back. Also a talented sharpener is great to know because they can sharpen a lot more than just saw blades.
If you are sharpening carbide, you want to select a diamond abrasive. Never use CBN on carbide chains or diamond on steel chains. They are incompatible.
