Dewalt Dws779 Vs Dws780 Buying Guide
Cutting Capacity and Accuracy
Both the DWS779 and DWS780 excel in providing accurate cuts, but they differ slightly in their capacity. The DWS780 generally offers a slightly wider cutting capacity at certain angles, particularly for larger crown molding. The DWS779, however, still provides ample capacity for most common projects. Consider the scale of your usual projects. Both saws utilize efficient blade designs and reliable motor systems ensuring clean and precise cuts every time. Check the precise measurements for the types of cuts you perform most often.
Motor Power and Performance
The motor power is a key differentiator between the two models. Both saws have powerful motors, but the DWS780 often boasts a slightly more robust motor for demanding tasks. This can translate to faster cutting speeds and the ability to handle denser materials with greater ease. While the DWS779’s motor is more than adequate for most users, those frequently working with hardwoods or thicker stock might appreciate the DWS780’s added power. Assess the types of materials you’ll be cutting to determine which motor best suits your needs. Consider also the saw’s torque.
Blade and Bevel/Miter Adjustments
Both saws are equipped with high-quality blades suitable for various materials. The ease and precision of bevel and miter adjustments are critical for accurate angled cuts. Both saws typically feature user-friendly adjustment mechanisms. The DWS780 often incorporates features that enhance the speed and accuracy of these adjustments, such as positive stops and detents at common angles. This can save valuable time and reduce the likelihood of errors. Familiarize yourself with how to quickly and accurately adjust these settings on both models. Check for the ease of changing blades.
Dust Collection Systems
Effective dust collection is essential for maintaining a clean and healthy work environment. Both the DWS779 and DWS780 are designed with dust collection systems. The DWS780 may incorporate a more advanced system, potentially featuring a more efficient dust port design. This can lead to less dust escaping into the air and a cleaner workspace. The design of the dust collection port is a key factor. Consider the type of vacuum or dust collection system you intend to use. Both models offer a reasonable level of dust collection.
Portability and Design
The portability of a miter saw is important, especially if you move between job sites. Both models have a manageable weight, but the DWS780, with its added features, might be slightly heavier. Consider how frequently you’ll need to transport the saw and the available space in your vehicle or workshop. The overall design and footprint of the saw also influence its portability. Check the dimensions and weight specifications. Consider the design of the base and handles. These factors impact portability.
