DEWALT Miter Saw 12 in Double Bevel Sliding Compound - Precision Cuts

In this review of the DEWALT DWS779 12 in sliding compound miter saw, the bottom line is simple: it is for carpenters, finishers, and serious DIYers who need accurate, repeatable crosscuts and miter work with heavy-duty capacity. The saw's strongest selling point is its combination of a powerful 3800 RPM motor and a precise miter system with a stainless steel detent plate, which produces clean, consistent cuts for moldings, crown, and dimensional lumber. Assembly is straightforward and the saw feels solid and ready for jobsite use right out of the box.

Key Features

• Powerful Motor: The 15 Amp, 3800 RPM motor delivers steady power for cutting through 2x14 lumber at 90 degrees and 2x10 at 45 degrees without bogging down.
• Precision Miter System: A stainless steel miter detent plate with 10 positive stops and a cam-lock handle with detent override gives fast, repeatable miter angles.
• Tall Sliding Fences: The tall, machined base fence supports up to 7-1/2 in of crown nested and keeps tall stock stable for accurate vertical cuts.
• Durable Sliding Mechanism: Dual horizontal steel rails with linear ball bearings and an innovative clamping mechanism provide smooth travel and long-term accuracy.
• Dust Management: The efficient dust collection system captures over 75% of generated dust, keeping the work area cleaner and improving visibility at the cut line.
• Wide Bevel Range: Bevels from 0 to 48 degrees left and right expand cutting options for compound angles and trim work.

Who It's For

The DEWALT DWS779 is ideal for professional finish carpenters, remodelers, and serious DIYers who frequently cut crown molding, wide base, and large dimensional lumber and need accurate, repeatable results. Its capacity for up to 2 in x 14 in crosscuts and robust build make it suitable for demanding jobsite use.

Those who primarily need a lightweight, highly portable saw for occasional small projects or who have tight workshop space to store a large sliding saw might prefer a smaller, more compact model. If low weight is a critical concern, this saw's solid construction is heavier than basic trim saws.

Pros & Cons

Pros

• Excellent cut accuracy thanks to the stainless steel detent plate and machined fence support.
• Generous crosscut capacity for 2x14 at 90 degrees and 2x10 at 45 degrees, useful for larger stock.
• Solid build quality and smooth sliding action from dual steel rails and ball bearings.
• Effective dust collection that reduces cleanup and improves visibility.

Cons

• Heavier than compact trim saws, which can be a limitation for frequent transport or one-person carry.
