FAQs
What is the best all-round electric saw?
The best all-round electric saw depends on your projects, but for most users, a 7-1/4 inch circular saw offers the best versatility. It cuts through plywood, lumber, and composite materials with ease, making it ideal for both job sites and home workshops. Cordless models now rival corded ones in torque and runtime, especially with brushless motors and advanced lithium-ion batteries.
If you’re looking for balance between power, weight, and ease of control, a mid-range cordless circular saw like the DEWALT 20V MAX or Milwaukee M18 Fuel is hard to beat. They deliver consistent cutting power, long battery life, and compatibility with other tools in their ecosystem.
Is a 12V circular saw any good?
A 12V circular saw can be surprisingly effective for light-duty tasks. It’s compact, lightweight, and ideal for cutting thin plywood, small boards, or trimming work. However, it’s not meant for heavy-duty construction or long rip cuts through thick lumber.
Think of a 12V model as your grab-and-go saw—perfect for DIY repairs, finishing tasks, or tight workspaces. It’s also great for beginners who need a manageable tool without the bulk or noise of larger saws. But if you’re doing framing or continuous cutting, you’ll want to step up to an 18V or 20V platform.
Is the M12 saw good for professional use?
The Milwaukee M12 circular saw is well-engineered, but it’s best suited for light professional tasks or punch-list work rather than full framing. It’s compact and easy to handle, which makes it ideal for overhead cuts or trimming sheathing in tight areas.
That said, for contractors who already use the M12 battery system, it’s an excellent supplementary tool. The M12 lineup is known for reliability, and when paired with the right blade, it delivers smooth, accurate cuts. However, for high-demand applications, most pros prefer stepping up to the M18 or 20V range for added torque and runtime.
Should I buy a corded or cordless circular saw?
This comes down to how and where you work. A corded circular saw provides unlimited power and is ideal for continuous, high-volume cutting. It’s perfect for stationary setups or when you’re always near an outlet.
A cordless circular saw, on the other hand, offers mobility and convenience. Modern models with brushless motors can cut through framing lumber or dense plywood just as effectively as corded ones. Plus, battery technology has improved so much that you can get hours of runtime on a single charge.
If you often move between job sites or work outdoors, go cordless. But if your projects demand nonstop cutting power, corded is still king.
Final Thoughts
The best battery circular saw combines freedom, power, and precision in one package. Today’s cordless models can easily rival corded tools, giving both professionals and DIYers the flexibility to tackle any job. Whether you prefer a compact 12V saw for light tasks or a 20V powerhouse for framing, choosing the right model ensures smoother cuts, better control, and faster work.
When it comes down to it, the best saw isn’t just about specs—it’s about how well it fits your workflow. Choose smart, cut better, and build with confidence.
