DeWalt is a renowned American brand that produces power tools and hand tools for construction, manufacturing, and woodworking industries. In this article, we'll compare two of their most popular miter saws: the DeWalt DWS779 and DWS780. Both models are highly praised for their performance and durability, but there are key differences that may influence your purchasing decision.
The DWS779 is a 12-inch, dual-bevel sliding compound miter saw. It's equipped with a 15-amp motor that delivers a no-load speed of 3,800 RPM, providing extended power and durability. It also features an exclusive back fence design that cuts dimensional lumber at 2x16 at 90 degrees and 2x12 at 45 degrees.
The DWS780 is also a 12-inch, dual-bevel sliding compound miter saw, but it packs more features. Along with the same powerful 15-amp motor, it introduces the XPS cross cut positioning system, which uses an LED light to show the cutline, making the cut more precise. It also has the same back fence design as the DWS779.
The most significant difference between these two models is the Cutline Indicator. The DWS780 features the XPS system, which casts an LED light onto your workpiece to show exactly where the blade will cut. This feature is highly appreciated by users for providing enhanced accuracy. Although the DWS779 does not come with this feature, it's still equipped with a traditional laser guide.
The addition of the XPS system makes the DWS780 more expensive than the DWS779. However, it's worth noting that the price difference can often be justified by the precise and efficient cuts that the DWS780 can make.
Dust Collection System
While both saws have dust collection systems, the DWS780 is known for having a more efficient one, capturing over 75% of generated dust. The DWS779, on the other hand, is reported to collect about 50% of the dust.
Motor and Blade
Both saws are equipped with a robust 15-amp motor that delivers a no-load speed of 3,800 RPM. They both use a 12-inch blade, offering ample cutting power for various applications, from heavy-duty framing and carpentry to delicate molding and trim work.
The DWS779 and DWS780 have similar cutting capacities. They feature a dual-bevel design that allows the saw to pivot left and right and tilt in both directions for compound miter cuts. Both models can cut 2x16 dimensional lumber at 90 degrees and 2x12 at 45 degrees.
Design and Durability
Both models have a rugged design to withstand tough working conditions. Their stainless steel miter detent plate comes with 10 positive stops, which improves productivity and ensures cutting accuracy. Their compact, lightweight design (56 lbs) also allows for easy transport and storage.
Choosing between the DeWalt DWS779 and DWS780 depends on your specific needs and budget. If you're seeking a more cost-effective but reliable miter saw for regular DIY projects, the DWS779 could be perfect for you. However, if you're a professional who values precision and can justify the higher price tag, the DWS780, with its XPS cutline indicator and better dust collection, could be a worthy investment.
Remember, the best tool is the one that fits your needs and budget. Whether you choose the DWS779 or DWS780, DeWalt’s reputation for quality and durability means you'll be getting a reliable tool designed to deliver top-notch performance.
