Drill Attachments to Skip (Circular Saw, Reciprocating Saw, Rivet Gun, Vegetation Cutter)
Circular saw attachment lacks blade speed and cuts imprecisely. Reciprocating saw attachment's internal plastic gears broke under load. Vegetation cutter has loose parts and poor design — the most dangerous attachment tested.
These fail in ways that range from "not worth the money" to "actually unsafe" — the drill-attachment format fundamentally can't replace a real circular or reciprocating saw safely.
