Overview
A round blade turned by a battery-driven motor does the cutting on this DEWALT circular saw. The listing states a capacity in inches and a material, and it gives no detail on the blade, battery or charger.
Cordless operation frees the work from extension leads, and a stated capacity gives a basis for matching it to lumber. The limitation is the sparse listing: the blade, battery and charger are all unnamed.
Who it's for
Framing or carpentry jobs away from a power outlet are the situation. Shoppers who need an itemized kit, a named blade or a documented guard and brake setup should look for a fuller listing.
Pros and cons
- Cordless battery operation
- Stated cutting capacity
- Fast blade speed rating
- High speed steel material
- Battery and charger unnamed
- Blade details missing
- Brake and guard unspecified
Performance notes
Blade speed comes from the battery-driven motor and is given as a revolutions rating. Cut quality depends on the blade and the rate of feed, and no blade is described. Run time follows the battery used.
