The DeWalt DWS780-QS 305mm Compound Sliding Mitre Saw is a professional-grade double-bevel sliding compound mitre saw designed for demanding woodworking, carpentry, construction and workshop applications. Its powerful 1675W motor and variable blade speed of 1900–3800 RPM provide controlled cutting performance across a wide range of professional applications.

The saw features a 305mm blade with a 30mm bore and a substantial cutting capacity. At 90°/90°, the manufacturer specifies a maximum cutting capacity of 303 × 110mm, while the maximum cutting depth is 170mm. This makes the DWS780-QS suitable for cutting large timber, mouldings, boards and other compatible wood materials.

The integrated XPS Shadowline crosscut positioning system provides an adjustment-free blade cut-line indication, helping the operator align cuts accurately. The dual horizontal sliding rails, large sliding fences and machined base and fence are designed to provide stability and repeatable cutting accuracy.

The double-bevel mechanism allows bevel adjustment up to 49° left and right, while the mitre system provides up to 50° left and 60° right adjustment. A stainless-steel detent plate with common positive stops and a cam-lock mitre control help make repetitive angle setting faster and easier.

The DWS780-QS also includes a depth stop for grooving and rebating operations, an AirLock-compatible dust port, dual sliding fences and a material clamp. These features make it well suited to professional carpenters, furniture makers, joiners, contractors and construction professionals.
