The DeWALT DWS780 miter saw combines a high-power 1675 W motor with precise cut capacity to handle a wide range of woodworking and trim applications. With a maximum no-load speed of 3800 RPM and a 305 mm blade, this miter saw delivers accurate crosscuts, bevels and mitres. It supports a cutting capacity of 212 x 76 mm at a 45° miter and is built with a stable, worksite-ready construction weighing 24.8 kg for improved control during repetitive cutting tasks.

Advantages

The powerful 1675 W motor and high idle speed enable fast, clean cuts in hardwoods and engineered materials. The large 305 mm blade diameter and generous cutting capacity at 45° mitre provide versatility for crown moulding, framing and general carpentry. Solid build and weight contribute to vibration reduction and cutting accuracy, while integrated fences and positive stops simplify angle adjustments and repeatable results.

Suitable for

• Crosscuts and mitre cuts for trim and moulding
• Bevel cuts for framing and joinery
• Cutting hardwood, softwood and engineered boards
• On-site carpentry and workshop projects requiring precise angles

How to use

Position the saw on a stable surface and secure the workpiece against the fence. Select the required mitre and bevel angles using the saw’s angle scales and positive stops, then lock the settings. Start the motor and allow it to reach full speed before making the cut. Guide the blade down through the material in a steady motion, maintaining contact between the workpiece and the fence for accurate results. After cutting, release the trigger and wait until the blade stops completely before lifting the guard and removing offcuts.

Usage recommendations

Use appropriate personal protective equipment such as eye and ear protection and dust extraction where possible. Inspect the blade for damage and use the correct tooth geometry for the material being cut. For repetitive angled cuts, use the saw’s positive stops and clamp workpieces to improve repeatability and safety.
