Score: 68/100
Milwaukee M12 Hackzall
Score: 75/100Rankings

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.

The BLACK+DECKER BDCR20B is a lightweight, budget-friendly cordless reciprocating saw designed for DIY homeowners tackling renovation, demolition, and general cutting tasks. It features a powerful 3,000 SPM motor and tool-free blade changes, making it user-friendly for rough cutting applications. However, its poor variable speed control and lack of precision limit its effectiveness for professional or fine-detail work.

Professional reviewers acknowledge the BDCR20B as a solid, well-built reciprocating saw with powerful cutting capability that is generally well-received for its class. They note that the construction quality is sufficient to withstand occasional drops and general workshop use. However, professionals identify the variable speed trigger's lack of precise control and the suboptimal blade release clamp lever design as primary areas where the tool falls short of professional standards.
Users generally view the BDCR20B as a solid choice for DIY projects, praising its combination of power, ease of operation, and good value for the price. Common praise highlights the lightweight design, solid construction, and quick blade changes. However, recurring complaints focus on the tricky variable speed control, faster-than-expected battery drain, and awkward blade clamp design.
