The First Power Tool You Should Buy
Don't let the table saw snobs fool you. A circular saw and a straight edge can build almost anything.
⚡ Quick Answer
A circular saw is the single most versatile power tool for the DIY woodworker. When paired with a straight-edge guide, it can match the accuracy of a table saw for breaking down sheet goods, while remaining portable and safer for solo work. For most users, a 7-1/4" sidewinder model (like the DeWalt 20V Max) offers the best balance of power and control. It is the first saw you should buy.
When I first started woodworking, I was intimidated. I thought I needed a massive table saw, a jointer, and a planer just to build a simple box. I let the "tool envy" stop me from starting.
I was wrong. The truth is, the most versatile tool in my shop isn't the big stationary machine in the center—it's the handheld circular saw tucked in the drawer.
The Safety Factor
Take myHidden Bookcase Doorproject. It required breaking down heavy 4x8 sheets of plywood. Trying to wrestle a full sheet onto a table saw by myself would have been dangerous and inaccurate. With a circular saw, I brought the tool to the wood, not the wood to the tool. It was safer, easier, and just as precise.
The 'Poor Man's Track Saw'
The biggest myth is that circular saws are only for rough carpentry. That's only true if you freehand it.
If you clamp a straight edge (like a level or a factory-cut piece of plywood) to your workpiece, your circular saw becomes a precision instrument. This technique is how I cut the long, straight structural components for myBarn Beam Light Fixture.
What to Look For
Cast magnesium shoes win every time
Blade Left vs Right
Blade-left saws allow right-handers to see the cut line easier. Blade-right is standard for sidewinders.
The Shoe
Look for a cast magnesium shoe (base). Stamped steel bends if dropped, ruining accuracy.
Rafting Hook
A hook to hang the saw on a 2x4. Essential for framers, handy for everyone.
My Recommendation
DEWALT 20V MAX 7-1/4"
The gold standard for cordless sidewinders. It has the power of a corded saw but weighs significantly less. The brake stops the blade instantly.

Circular Saw FAQ
For breaking down sheet goods (plywood), absolutely. In fact, it's often safer and more accurate for a solo woodworker. For small, repetitive rip cuts, a table saw is faster, but a circular saw with a guide is surprisingly capable.
A sidewinder (motor on the side) is lighter and spins faster—great for general use. A worm drive (motor behind the blade) has more torque and is heavier—ideal for framing and cutting wet lumber. For most DIYers, a sidewinder is perfect.
Never freehand it. Clamp a straight board (like a factory edge of plywood) to your workpiece. Measure the offset from your blade to the base plate edge, set your guide, and ride the saw against it. This is the 'poor man's track saw'.
Modern 18V/20V/60V cordless saws are incredible. Unless you are running a production shop cutting all day, go cordless. The freedom from snagging cords on a sheet of plywood is worth the price of batteries.
Blade Selection
- 24T:Framing/Ripping: Fast, rough cuts. Good for 2x4s.
- 40T:General Purpose: Good balance for ply and crosscuts.
- 60T:Fine Finish: Clean cuts in plywood/veneer. Slow feed.
Kickback Warning
Kickback happens when the wood pinches the blade.
NEVER cut a board supported on both ends (like between two sawhorses) with the cut in the middle. The board will sag, pinch the blade, and the saw will fly back at you.
Always let the cut-off piece fall away freely.
