Circular Saw DeWALT DCS579NT-XJ

The DeWALT DCS579NT-XJ is a portable circular saw designed for efficient, accurate cutting of wood and wood-based materials. It features a 19 cm blade diameter and a brushless motor that delivers a high idle speed, enabling fast through-cuts and consistent performance on construction sites and in workshop settings. With a maximum cutting depth of 6.1 cm at 90º and a compact, lightweight build of 3.7 kg, this saw balances power and maneuverability for both professional tradespeople and DIY users.

Advantages

The brushless motor reduces maintenance needs while improving runtime efficiency and delivering stable power at high speed. A maximum idle speed of 5800 RPM allows cleaner, quicker cuts through timber and sheet materials. The saw’s lightweight 3.7 kg construction and ergonomic design make it easier to guide and control during extended use. Compact dimensions and robust build provide portability and jobsite durability without sacrificing cutting capability.

Suitable for (tasks / use cases)

• Crosscuts and rip cuts in softwood and hardwood panels
• On-site framing, decking and carpentry work
• Cutting plywood, MDF and OSB sheets to size
• Renovation and DIY tasks requiring portable circular saw performance

Key specifications

• Blade diameter: 19 cm
• Motor type: brushless
• Maximum idle speed: 5800 RPM
• Maximum cutting depth at 90º: 6.1 cm
• Weight: 3.7 kg

How to use

Before use, fit a blade suitable for the material and ensure the saw is securely mounted or held with both hands. Set the depth of cut to slightly exceed the material thickness for a clean pass, and verify the blade guard and riving knife move freely. When cutting, maintain a steady feed rate without forcing the blade; allow the brushless motor to reach operating speed. For repeated or guided cuts, use a straight edge or guide rail and secure the workpiece to prevent movement.

Usage recommendations

Use compatible DeWALT batteries and chargers to ensure optimal performance and protection circuits. Wear appropriate personal protective equipment including eye and ear protection and a dust mask when cutting wood or sheet materials. Inspect blades regularly for wear and replace them to maintain cutting quality and reduce motor load.
