Overview
A corded electric saw running on a 120 volt, 1800 watt motor, built around a metal housing with a 7 inch cutting capacity.
The 1800 watt motor and 7 inch capacity point to a full-size circular saw for framing and general construction cuts rather than a compact trim saw. The listed 31.7 pound weight runs heavier than a typical handheld saw of this size, which may reflect boxed shipping weight rather than the tool alone.
- 120 volt corded electric power
- 1800 watt motor
- 7 inch cutting capacity
- Metal housing
Who it's for
Suited to builders and DIYers doing framing, decking or general lumber cuts who want a corded saw with steady 120V power rather than battery runtime limits. Less suited to anyone needing a lightweight, cordless option for overhead work.
Pros and cons
- 1800 watt motor for consistent cutting power
- 7 inch blade capacity handles standard framing lumber
- Corded so no battery to run down
- Corded only, limits mobility away from an outlet
- Listed weight runs heavy for a handheld saw
Performance notes
An 1800 watt motor at 120 volts delivers consistent power without battery drain, which matters most on long rip cuts through thick or dense lumber where a battery-powered saw would bog down.
