Dewalt Dws715 vs dws779

Comparing the Dewalt Dws715 and the dws779 may be difficult, but only if you do not know the saw tools. Both are incredible tools, with similar features and functions. However, it is the differences that make each of them unique. Make a comparison of design, speed, power, and accuracy. That way, you can find your best interests in one of the tools. Below is a review of each miter saw, and its pros and cons. 

Overview of the Dewalt DWS715

The 12-inch Single-Bevel Compound Miter saw is powered by a 15 Amp motor. It runs at 4,000 rpm, delivering extended power and durability. It features a stainless-steel miter detent plate and cam miter lock with accuracy, and durability with easy adjustments. 

Tall sliding fences support 5-1/2-inch of base molding vertically and 5-1/2-inch of crown molding vertically nested. Its lightweight design and built-in carry handle make it portable.

The tool is sturdy and the spring action to return the saw blade to the upright position is slow and smooth. Being a single bevel miter saw means it only leans to the right. 

If you do a lot of trim molding, you might need a dual-bevel saw that can lean in both directions. That way, you do not have to flip the workpiece over when changing the angle direction of the bevel cut. Since most miter saws are single-bevel they can still cut any crown and trim molding with this type. 

Pros

  • Clean
  • Accurate
  • Taller fence
  • Affordable 
  • Quick

Cons

  • Low-quality dust collection
  • No laser

Features of Dewalt DWS715

Cutting capacity

This Dewalt 12-inch miter saw can crosscut, miter cut, bevel cut, and compound cut. The tall fence can cut vertical baseboards up to 6-1/2 inch tall. That makes it ideal for baseboards, trim molding, and crown molding.

At a 45-degree angle miter cut, you can slice through a 2″ x 6″ board in a single pass, making it a saw for framers and deck builders. The capacity of this miter saw makes it ideal for any DIY project, construction job, or trim molding project. 

Power

It features a 15 amp 4,000 rpm motor, which can handle softwoods and hardwoods. 

Blade

It features a large 12 inches diameter blade, and you can crosscut 90 degrees through a 2″ x 8″ board in a single cut. It handles a dimensional 4×4 with ease.

Dust collection port

The dust collection port on this saw is typical of standard miter saws. It does not catch much dust. If you add a shop vac, you can gather a larger percentage. Attaching a dust evacuation system is a better way to collect dust.

Features of Dewalt dws779

Positive stops

Dewalt dws779 features a stainless steel miter detent plate with ten positive stops.

Fence support and steel rails

The machined base fence support makes the precise miter system. Its dual horizontal steel rails have an innovative clamping mechanism and linear ball bearings, for accuracy and durability.

Dust collection system

It has an efficient dust collection system that captures over 75% of sawdust.

Design and build quality

Dewalt dws779 has a compact and sturdy design, a linear ball bearing system, and an advanced clamping mechanism with dual steel rails for accuracy and precision. The saw design does not require much adjustment.

Positive Depth Stop

One of the most overlooked features of a miter saw is the adjustable depth stop. This feature comes in handy when you need it and when you know how to use it. When making redundant cuts that do not penetrate the wood, engage the adjustable depth.

Flip down the stop, and adjust the socket screw by loosening the wingnut first. That allows you to adjust the cutting depth. When you are ready to make through cuts again, raise the stop. That keeps your adjustment where you want it, and you can flip the stop down to re-engage the stop.

What could have been better

Dewalt Dws715

  • A better quality dust collection performs better.
  • A laser brings more accuracy.

Dewalt Dws779

  • It could have been light enough to move easily.
  • A laser would have made smoother cuts. 

Similarities

  • They have the same blade diameter.
  • Both of these power tools are compound miter saws.

Differences between Dewalt DWS715 and DWS779

  • Dws715 is lighter than dws779.
  • Dws715 operates at a higher speed than dws779.
  • The DWS779 is a sliding compound miter saw and the DWS715 is not.
  • The DWS779 can cut wider boards than the DWS715.
  • The DWS779 is a dual bevel miter saw while the DWS715 is a single bevel miter saw.
  • The DWS715 has 4 more bevel stops than the DWS779.

The verdict

Both saw tools are incredible. However, you cannot have both tools but one that best serves your interests. The Dewalt DWS779 is more efficient when working in a dusty area. If you have limited space in your workshop, you may have to use the Dewalt dws715 since it is smaller. By now, you should have decided on the miter saw you want.
