7inch Makita Cordless Circular Saw

Voltage: Usually 18 V for light/medium tasks, 36 V for heavy-duty or professional use. Higher voltage improves cutting power and runtime. Power: Motor output ranges from ~360 W to 1,500 W equivalent (peak), depending on battery size and motor type. Brushless motors provide better efficiency and maintain power under load. RPM: Blade spins at 3,500–5,500 revolutions per minute (no-load), ensuring clean, fast cuts. RPM may drop slightly under load. Blade Diameter: Commonly 165 mm (61⁄2′′) for general use, 140 mm (51⁄2′′) for light-duty, and up to 185 mm (71⁄4′′) or more for heavy-duty cutting. Cutting depth is roughly half the blade diameter. Portability: Lightweight and ergonomic design makes it suitable for DIY, construction, and woodworking tasks in locations without easy access to electricity.
