The DEWALT 20V MAX Cordless Reciprocating Saw (DCS387B) is a compact, lightweight tool designed for cutting in tight spaces like between studs. It features a brushed motor, a variable speed trigger up to 2,900 SPM, and a keyless 4-position blade clamp for quick changes. It is ideal for professionals or DIYers needing access in confined spaces, such as plumbers, electricians, or remodelers working between studs or in walls.

The Milwaukee 2420-20 is a compact, one-handed cordless reciprocating saw optimized for tight spaces and overhead applications with a 12V power system. It lacks the power for heavy-duty demolition and requires a separate battery purchase. It is best suited for plumbers, electricians, and remodelers working in confined areas.
