FAQs
How Big of a Board Can a 12 Inch Sliding Miter Saw Cut?
A 12-inch sliding miter saw can typically cut boards up to 12 to 16 inches wide, depending on the model and design. The sliding rails allow the blade to move forward and backward, increasing its cutting capacity far beyond standard non-sliding saws.
For instance, a top-tier 12-inch model like the DEWALT DWS780 can handle a 2x16 board at 90 degrees and a 2x12 board at 45 degrees. This makes it ideal for wide baseboards, crown molding, and framing materials. In short, if you frequently cut large lumber or trim, a 12-inch sliding miter saw provides the reach and flexibility you need.
Which Is Better, a 10 or 12 Inch Sliding Miter Saw?
The choice between a 10-inch and a 12-inch sliding miter saw depends on your project needs.
A 10-inch miter saw is lighter, easier to transport, and usually more affordable. It’s perfect for smaller jobs like trim work, flooring, or furniture making. The smaller blade spins faster, offering smoother cuts with less vibration.
On the other hand, a 12-inch sliding miter saw provides greater cutting capacity and power. It can handle wider and thicker boards, making it ideal for framing, cabinetry, and heavy-duty woodworking. The downside? It’s heavier and may produce slightly rougher cuts due to the larger blade diameter.
In short, if you value portability and precision, go for the 10-inch. If you need raw cutting power and versatility, the 12-inch is the better long-term investment.
What Is the Difference Between DWS779 and DWS780?
The DEWALT DWS779 and DWS780 are both 12-inch double bevel sliding compound miter saws, but they differ mainly in features and price.
-
Cutting Performance: Both deliver identical power (15-amp motor, 3,800 RPM) and cutting capacity.
-
XPS Cut Line System: The DWS780 includes an XPS LED shadow line system, projecting an accurate cut line without calibration. The DWS779 lacks this feature, relying instead on a traditional laser guide or manual marking.
-
Price: The DWS779 is usually more affordable, making it an excellent value for those who don’t need the LED system.
-
Convenience: The DWS780’s XPS system improves visibility and accuracy, especially in low-light conditions.
In short, both are built tough, but the DWS780 offers a premium cutting experience with enhanced precision.
Why Is DWS779 Discontinued?
The DEWALT DWS779 was discontinued as part of the brand’s product update to streamline their miter saw lineup. DEWALT shifted focus toward models like the DWS780, which incorporate modern features such as the XPS LED system and improved ergonomics.
Another reason is manufacturing efficiency—consolidating production around newer models helps reduce costs while maintaining quality standards. However, the DWS779 remains popular among woodworkers and contractors because of its reliability and performance. Many hardware retailers still carry remaining stock or refurbished units, making it a strong budget-friendly option.
Final Thoughts
Choosing the best 12 inch sliding compound miter saw comes down to balancing power, accuracy, and convenience. A well-built saw can handle large boards, deliver consistent precision, and last for years with proper care. Whether you’re upgrading from a smaller model or buying your first professional-grade tool, a 12-inch sliding miter saw offers the perfect combination of reach, control, and versatility. For woodworkers who demand reliability and accuracy in every cut, it’s a game changer.
