The Mk Diamond 165238 Concrete Saw Pointer Wheel Assembly provides precise guidance for accurate cutting with compatible concrete saws. This assembly includes the pointer wheel and mounting components that attach to the saw’s guide arm, helping operators maintain a straight cutting line along marked layouts. It works by rolling smoothly along the work surface as the saw moves, allowing the pointer to indicate and follow the intended cut path. Engineered for proper fit and straightforward installation, it aligns with the saw’s original design. Ideal for replacing worn or damaged guidance wheels, this pointer wheel assembly supports consistent, controlled cutting results on concrete and masonry surfaces.
