✕DO NOT FORCE THE FIT
- Epoxies — not a judgment call; the catalog row bars the whole paint tier ("Not for use with epoxies"), and a two-part resin kicking on a polypropylene rotor is permanent.
- Joint compound, texture, grout, mortar: the impellers and the shank are sized for liquids; stiff material wants the welded-steel Mudslingers (46555/46560 class) and their torque.
- A five-gallon pail: the 11" shaft cannot work a pail floor with the drill above the rim — that is the 43430's one-line job description.
- And routine stir-maintenance of a fresh can: a paddle does that for free; this tool earns its chuck time when the settle is past what sticks fix.
