Overview
Filed under Tools, Specialties, the FLEX FX5221-Z runs on a 24 volt battery and weighs 7.3 pounds, holding a 4.3 rating across 78 reviews.
FLEX's 24 volt line lets one battery pack cover several tools in the lineup, which is likely why this listing sits under a general Specialties heading rather than naming a specific tool type. The spec table gives voltage, a 24 watt motor rating and weight, but not the task the tool is built for, so check the listing photos to confirm fit before buying.
