Buy If You…
This product excels in three specific scenarios:
- You routinely perform demolition cuts through 2×8 lumber and 3/4 in. plywood on-site. The 2720-21 Reciprocating Saw includes a POWERSTATE brushless motor and adjustable shoe to maintain cutting contact under load. This configuration avoids carrying a corded saw and replaces a separate battery and charger purchase that bare-tool buyers typically face, saving roughly $100–$150 in added power accessories.
- You need a cordless saw that runs full shifts where portability matters and outlets are >10 ft. away. The Milwaukee M18 Reciprocating Saw ships with an M18 REDLITHIUM XC 4.0 battery and M18/M12 charger so crews start work without sourcing batteries. Including the battery and charger in the kit avoids buying these components separately, which can add about $100–$200 to a bare-tool total.
- You require an LED-lit tool for cuts in 2 ft. to 6 ft. deep framing bays or attics. The 2720-21 includes an integrated LED light and rafter hook for hands-free staging during repetitive cuts. These features reduce time on ladders and lower setup time per cut by measurable minutes across a day, cutting needless tool swaps and delays.
Skip If You…
Two deal-breakers make this the wrong choice:
- You need published stroke length or SPM specs for precise metal pipe cutting tolerances. Consider the DEWALT DCS380B at $99 as an alternative. The DCS380B lists a 1-1/8 in. stroke and up to 3,000 spm, which gives exact metrics for metal and pipe work that are not listed for the 2720-21.
- You prioritize the lowest tool price and already own a compatible battery platform. Consider the DEWALT DCS367B at $149.89 instead. The DCS367B is a compact bare tool with documented specs and a lower upfront cost for users who do not need an included battery and charger.
Value Calculation
At $299.99, the Milwaukee 2720-21 kit bundles the saw, an M18 REDLITHIUM XC 4.0 battery, and an M18/M12 charger, avoiding separate purchases that can total approximately $100–$200.

The 18-Volt Brushless Cordless Reciprocating Saw Kit suits contractors and serious DIYers who need a ready-to-run M18 system and on-site portability across jobs measuring 4–12 hours.
