Power & Motor

Both saws are corded and run on 120 V. The R4512 draws 13 amps. The SPT99T-01 draws 15 amps. In the U.S., standard residential circuits are 120 V, 15 A, which will support either of the products.

The R4512 motor spins at 3450 rpm and the SPT99T-01 motor spins at 5300 rpm. Don’t get too caught up in these numbers, since the manufacturers measure them under ideal conditions, so they don’t have a meaningful impact on the saw’s real-world capability to handle different material.

Blade Compatibility

Both table saws have a 5/8” arbor. The R4512 accepts 10” diameter blades. The SPT99T-01 takes 8 1/4” diameter blades. 10” is a very popular diameter for table saw blades, meaning you should be able to find a huge variety of blades to suit your needs. Most 8-to-10” blades have a 5/8” arbor hole, so this size arbor gives you a lot of options.

The Ridgid accepts dado blades up to 13/16” thick. The Skilsaw takes dado blades up to 1/2” thick.

Size & Capacity

The Ridgid has 30” of rip capacity to the right side of the blade and has 15” of rip capacity to the left. The Skilsaw has 25” of rip capacity to the right side and has 12” of rip capacity to the left of the blade. In general, a larger rip capacity is better, but it typically also means a larger and heavier saw. Think about what types of rip cuts you’ll be making and choose the right size saw for you.

The R4512 can bevel the blade up to 45°, is able to cut up to 3 1/4” deep at an angle of 90°, and can cut up to 2 1/4” at 45°. The SPT99T-01 can bevel its blade up to 46.5°, will cut up to 2 5/8” deep at a 90° angle, and is able to cut up to 1 7/8” at an angle of 45°.

The table on the Ridgid has a width of 40” and a depth of 27”. The table on the Skilsaw has a width of 23 1/2” and a depth of 21 1/2”.
