Which is better for cutting large boards?

The DW788. Its 20-inch throat gives 2 more inches of clearance than the 18-inch saw, which matters on wide panels and long curves.

Is the 18-inch saw's stronger motor a real advantage?

On paper, yes: 1.6 amps versus 1.3 amps. In practice the DW788's higher top speed of 1,750 SPM and lower-vibration arm usually matter more for detail work.

Which one bevels further?

The DW788. It tilts 45° left and 45° right; the 18-inch saw tilts 45° left but only 15° right.

Is one worth the extra money?

Neither costs extra right now. Both are $299 as of November 7, 2026, so pick on features.

The DW788 has a documented 3-year limited warranty and a cast iron table. The 18-inch saw lists no warranty, so its long-term support is less certain.

Which is easier to move around a shop?

The 18-inch saw, with its aluminum table. The DW788 weighs 56 lbs.

DeWalt DW788 Scroll Saw vs DeWalt 18" Scroll Saw

Both saws cost $299 as of November 7, 2026 — the DW788 at Lowe's and the 18-inch saw at Amazon — so the choice comes down to features, not price. Buy the DW788 for the larger 20-inch throat, the 400-1,750 SPM range, the cast iron table and the double parallel-link arm that cuts vibration. Buy the 18-inch saw only if you want the slightly stronger 1.6 amp motor and a lighter die-cast aluminum table.

Today the DeWalt 18" Scroll Saw costs $403.11 less at its best price.
