DEWALT DW4725 Masonry Blade
DEWALT’s DW4725 stands out for masonry work, including stucco. The blade employs a high-performance diamond matrix that delivers up to 200 times longer life than conventional abrasives and enhanced material removal. A thinner kerf supports faster cuts and less dust generation, helping to keep work areas cleaner and reducing heat buildup during dry cutting. The continuous rim design facilitates stable, precise cuts on cementitious materials, while the 4-1/2 inch diameter and 7/8 inch arbor are common fits for many angle grinders and circular saws. This blade is well suited for long runs on masonry projects where blade life and cutting efficiency are critical.

Buying Guide
Key considerations help choose the right blade for stucco projects, balancing material properties, equipment compatibility, and job conditions.
- Material and application: Stucco and cementitious siding require blades designed for masonry. Diamond blades with segmented or turbo designs offer efficient debris removal and heat management, reducing the risk of glazing and warping during prolonged cuts.
- Blade design and cut quality: Segmented blades excel in heavy-duty masonry, while continuous-rim blades provide smoother cuts on softer cementitious materials. For stucco, a segmented or multi-purpose diamond blade typically delivers better life and cutting speed.
- Size and arbor compatibility: Confirm the blade diameter and arbor size (for example, 4″ to 6″ diameters with 7/8″ or other arbors) match your grinder or circular saw. Mismatches can cause unsafe operation or poor cut quality.
- Wet vs dry cutting: Wet cutting helps with dust suppression and cooling but requires a water source. Dry cutting is convenient but may create more dust; use dust extraction when possible and follow safety guidelines.
- Durability and blade life: Look for blades with a robust diamond matrix and cooling design. Long-life blades reduce replacement frequency, especially on large stucco renovations.
- Tool compatibility and safety: Ensure the blade integrates with your tool’s guard, spindle, and RPM rating. Always wear eye protection, a mask or respirator, and hearing protection when cutting masonry materials.
- Price vs performance: Higher-quality blades typically offer longer life and faster cutting, which can reduce overall project time and tool wear. Consider project scope and frequency of use when evaluating value.
When selecting a blade, homeowners should assess the project’s scale (small repairs vs. full stucco replacement) and whether cutting will occur indoors or outdoors. Professionals may prioritize long blade life and speed for frequent use, while DIYers may value versatility and ease of use. For jobs involving multiple materials, a multi-purpose blade with proven performance on brick, stucco, and concrete can simplify tool inventory and reduce the need for blade swaps. Regardless of the blade chosen, pairing cutting with appropriate dust management and PPE is essential for safe, efficient work.
