Amana Tool STF-4-30 Pair of Blade Stabilizers 4 Inch D x 30mm Bore
Used in conjunction with the collars provided on your machine to increase the overall stiffness of the saw blade. Particularly useful for think erf saw blades. Unlike other stabilizers, these are made from the same quality tool steel as Amana Tool's® industrial saw blades. The steel is ground (not stamped) and is extremely flat on both sides to reduce run-out and vibration.
Please note that the depth of cut will be reduced slightly and the table insert (if applicable) may obstruct the stabilizers when raising the blade height on table saws. You may use one or two stabilizers, depending on application and arbor length.
