How to Choose a Cordless Circular Saw
① Choose by Voltage (V)
The first criterion for choosing a cordless circular saw is voltage. 18V is suited for DIY users who already own batteries, or for light job site work. 40Vmax (Makita) and 36V Multi-Volt (HiKOKI) are designed for continuous cutting of thick and hard materials on professional job sites — the difference in power and stamina is substantial. It’s most efficient to check your existing battery brand and voltage first, then narrow down your model choice.
② Choose by Blade Diameter (mm)
165mm is the mainstream general-purpose size. With a maximum cut depth of 66mm, it handles everything from 2×4 lumber to laminated wood. 125mm is compact and lightweight, ideal for fine cutting of interior materials, flooring, and finish carpentry. For general woodworking and construction work, 165mm is the safe choice.
③ Battery Compatibility
Makita, HiKOKI, and Bosch batteries are not interchangeable. If you’ve already built up a tool collection on one platform, sticking with the same brand will significantly cut down on additional battery costs. If you’re starting fresh, decide on a brand after thinking about the full range of tools you plan to acquire.
④ Special Uses (Dust Collection Sync / Plunge Cutting)
If you need wireless dust collector sync, the HS002GZ or C3606DB is your answer. For finish carpentry requiring groove cutting or plunge cuts (cuts without an exit), a plunge circular saw like the SP001G is effective. When your use case is clear, a purpose-built design will improve work efficiency more than a standard model.
