Before starting a saw project, balance your CMT blade in your table saw first with the CMT Balance Blade & Sanding Disk. Mount the Balance Blade & Sanding Disk in your table saw and line it up with a square for accuracy. Remove the balance blade and mount your saw blade for true and precise cuts. Use the Balance Blade & Sanding disk also as a sander by attaching a self stick sandpaper disk to the balance blade and assembling it on your table saw.
