-
High-Speed Stability: Rated for up to 15,200 R.P.M, providing smooth operation and reduced vibration for the operator.
-
Safety Reinforced: Features standard safety icons for mandatory protective gear (goggles, ear protection, dust mask, and gloves).
Safety & Usage Instructions
-
PPE Required: Always wear eye protection, hearing protection, a dust mask, and heavy-duty work gloves.
-
Machine Compatibility: Ensure your angle grinder’s guard is properly installed and that the tool’s R.P.M. does not exceed the disc’s maximum rating.
-
Storage: Keep in a dry, cool place to prevent moisture absorption, which can compromise the resin bond.
Quality Assurance: “The Name That Means Quality” – SMT cutting discs are manufactured to meet rigorous professional standards for consistent performance across construction and metalworking projects.
