Main Review

Going back over the mitre saws released by Dewalt, one of their very best models was the DW718XPS. This later evolved into the DWS780 and became hugely popular as a great work horse of a mitre saw.

In this improved model, they have added increased capacity, a brighter lit XPS system, more portability and better dust extraction. For professionals and construction workers, this one offers a massive cutting capability

One feature buyers talk about a lot is the XPS Shadow line cut indicator. When you need a fast cut, but one that is highly accurate, then this shadow system works great. When combined with a light, it really makes the whole cutting process a great deal easier.

This saw can cut decking, sleepers, posts, skirting boards and just about anything that you can throw at it. It is also easy to use despite the many functions. It will take a little time initially to familiarise yourself with it. Once that is done though, you will see that it is very plain sailing.

The quick release bevel stop setting is useful, as is the mitre and bevel controls. There is a large dual sliding fence ideal for larger material cuts at any angle. This DWS780 model is really easy to move around the workplace.

Combine all of that with decent dust control, and electronic speed, and you have one powerful and multi-purpose saw.

Our Verdict on the Dewalt DWS780-GB Compound Slide Mitre Saw with XPS

This 305 mm mitre saw has a very powerful heavy duty motor that delivers really powerful cutting for all types of materials. Buyers really loved the The XPS Shadow line cut indicator as it allowed them to do a quick and accurate alignment of the blade.

That along with the XPS light illuminating the work piece made their life a great deal easier.

This saw also has a large dual sliding fence that gives support when cutting large materials. The rails also allowed precision when cutting materials up to 345 mm wide. The saw features cam action mitre lock functions, making it faster and easier to adjust angles between 0-50 Degree left and 0-60 Degree right.
