This WORKPRO groove joint pliers set delivers reliable heavy-duty performance for both professional tradespeople and DIY enthusiasts, built to handle plumbing, automotive repair and various home improvement projects with ease.

Constructed from premium CrNi steel, these groove joint pliers boast impressive hardness and outstanding long-term durability. Each tool undergoes black finishing and precision polishing treatment, which delivers excellent corrosion resistance and effectively protects the pliers from rust and wear, extending the overall service life even with frequent use in damp or tough working environments.

The pliers are engineered with angled jaw teeth to create a powerful, secure gripping force. The specially shaped teeth can firmly bite onto pipes, rods, shafts and fasteners in flat, round, square and hexagonal profiles.
