Power & Motor

Both saws are corded, run on 120 V, and draw 13 amps. Standard U.S. residential circuits are 120 V, 15 A, which will support either of the products.

Both table saws have motors that produce 3450 rpm. Dont pay too much attention to these numbers, because the manufacturers measure them under no-load conditions, and they dont have a useful impact on the saws real-world ability to handle different material.

Blade Compatibility

Both saws accept 10 diameter saw blades and have a 5/8 arbor. 10 is the most common diameter of table saw blade, so it should be no problem to find a huge assortment of blades for any purpose. Most 8-to-10blades have a 5/8arbor hole, so this size of arbor maximizes blade compatibility.

Both products take dado blades up to 13/16 thick. The R4520 accepts dado blades up to 6 in diameter.

Size & Capacity

Both table saws can rip up to 30 of wood on the right of the blade and have 15 of rip capacity on the left side. In general, more rip capacity is better, but it often also means a larger, heavier saw. Think about how big of rip cuts youll be making to help choose the right size saw for you.

Both saws can cut up to 3 1/4 deep at a 90° angle and can cut up to 2 1/4 at a 45° angle. The R4512 can bevel its blade up to 45°. The R4520 can bevel up to 4°.

The tables on both products are 40 wide and 27 deep.
