The 4″ blade stabilizer (STAB4) is a precision-ground steel collar that mounts against thin-kerf saw blades to dampen vibration and flutter — for straighter, quieter, more accurate cuts and longer blade life. It is .125″ thick with a 5/8″ bore.
Be sure to buy two piece to make a set for sandwiching thin saw blades!
This stabilizer can be modified to fit your setup with custom pinholes or a larger bore. Pairs with super-thin-kerf blades on table saws, sliding saws, and panel saws.
