When you look at the field of 18V cordless circular saws, it’s hard to make a decision. Obviously, if you’re already invested in a particular battery platform there is a lot of good reason to stick with what you know. The problem is, there are several 18V cordless saws that truly outperform the competition—so much so that you may want to invest in a new platform to get the cordless cutting power you need. Earlier this year we did a 7-1/4″ circular saw shootout and noticed significant differences between cutting speed, run time, and power. In this buying guide we list the specs and features for finding the best 18V cordless circular saw on the market today—and we lay it out so you can see the entire field of new tools. Similar to how we structured the Best Compact 18V Drill Buying Guide, this guide will show you the top performance specs in each area. That way, you can determine what is important to you. As always, we’ve included links to reviews wherever possible.
The goal with 18V cordless circular saws is going to come down to cutting power, cutting speed, and run-time. If you can get a full day’s work out of a battery or two, then you’re going to be in good shape. Overall, we like saws that have enough clearance (depth of cut) to get through 2x material at a 45 degree bevel. You’ll also note that we included bare tools so that those of you with existing kits and batteries can understand the minimal cost to simply add the top to your existing collection. For those just starting out, or switching brands, you’ll want to look up the kits which typically include a couple batteries and a charger.
The following grid represents the currently shipping cordless 18V circular saws on the market that we feel represent the best solutions from each manufacturer. There may be secondary models, older products, and different variations with battery options and accessories, but the bottom line is that this should give you pretty good handle on what’s available to you as a Pro consumer. While some of these saws will have higher speeds, several models compensate with extra torque to power though cuts without bogging down. You also have to decide how much you’ll use this tool, and what kind of cutting depth you need for the materials you more frequently interact with on a regular basis. If you need the best 18V cordless circular saw that can run all day, then look to the available battery technology so that you understand what’s available to power the tool to its highest potential.
