A clear role beside the circular saw
2737-20 adds curved cutting to an existing M18 kit. Decking around posts and supported panel openings are more persuasive reasons to buy it than expecting it to replace every circular-saw cut. Lay out the opening and choose the permitted approach before cutting. A builder working mostly on straight stock may use it less often than the drill, driver and circular saw already in the bag.
Visibility and finish are separate
The documented LED, switchable blower and extraction tube address seeing and collecting at the cut. The orbital setting, blade and feed govern another part of the result. Owner feedback includes clean-cut praise alongside criticism of the attachments becoming dusty. Treat that as a prompt to check the actual collection setup and trial the accessory combination, rather than a guarantee that every supplied part suits every task.
Keep the power purchase coherent
The -20 package is tool only. Existing M18 batteries can keep the extra purchase straightforward, but a new buyer must price a usable power setup. Compare DCS334B for DeWalt owners and XVJ04Z for LXT users against the same opening and finish requirement. Milwaukee’s published runtime uses specified conditions; we have not reproduced those cuts or compared daily endurance between the alternatives.
