HOPKINS GR05 UNDERWATER GRINDER 125mm (5″)

The Hopkins GR05 125mm (5") underwater grinder is a compact, powerful tool for cutting, grinding, cleaning, and finishing a wide range of materials underwater.

Designed for commercial divers, it is available with either an M14 or 5/8”-11UNC spindle and supplied with a hub nut and drive flange. A wide range of accessories - including cutting discs, grinding discs, flap discs, specialty discs, and brushes - are compatible with the GR05.

Lightweight yet robust, the GR05 features a safety trigger system to prevent accidental operation and a rotatable head for diver comfort. Its excellent power-to-weight ratio makes even tough tasks manageable while remaining easy to handle.

Ideal for small to medium-sized underwater jobs, the GR05 complements larger grinders like the Stanley GR29, giving divers the right tool for each application. The unit comes in a protective carry case with 125mm all-cut and all-grind diamond discs.
