Best Sale Lee Valley Blade Stiffeners

Saw blades with small arbor washers are prone to flutter in use.

One of the best-kept secrets in woodworking is that arbor washers (or stiffening plates) should be at least 1/3 the diameter of the blade used. They can be more than 1/3 the diameter if depth of cut is not reduced unacceptably. A blade is subject to substantial stress in use, and anything that increases stability will improve the cut, especially with thin-kerf blades.

The 3 1/2″ diameter size is for 8″, 9″ and 10″ saw blades; the 5″ is for 10″ and 12″ blades.

Sold by the pair, each side is 1/4″ thick and hollow ground to a 3/8″ wide rim for good seating. 5/8″ arbor.
