Power & Motor

Both products are corded and run on 120 V. The R4520 draws 13 amps. The RTS12 draws 15 amps. Standard U.S. residential circuits are 120 V, 15 A, which will support either of the saws.

The R4520 has a motor that spins at 3450 rpm and the RTS12 has a motor that spins at 5000 rpm. But you shouldn’t get too caught up in the RPM numbers, since the manufacturers test them under ideal conditions, and they don’t have a meaningful correlation with the saw’s real-world ability to handle various types of material.

Blade Compatibility

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

The Ridgid takes dado blades up to 13/16” thick and 6” in diameter. The Ryobi accepts dado blades up to 1/2” thick.

Size & Capacity

The Ridgid has 30” of rip capacity on the right side of the blade and has 15” of rip capacity on the left of the blade. The Ryobi has 12” of rip capacity on the right side and has 8” of rip capacity on the left. Generally speaking, more rip capacity is better, but it often also means a larger, heavier saw. Think about how big of rip cuts you’ll be making to help choose the right size saw for you.

The R4520 can bevel the blade up to 4°, 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 RTS12 can bevel its blade up to 45°, can cut up to 3” deep at a 90° angle, and can cut up to 2 1/2” at a 45° angle.

The table on the Ridgid is 40” wide and 27” deep. The table on the Ryobi is 27.36” wide and 30 1/2” deep.
