Choosing the correct diamond saw blade saves time, reduces tool cost, and improves cut quality. This guide compares blade selection for concrete and granite applications.
Concrete and granite place very different demands on a diamond saw blade. Concrete is abrasive and often contains steel reinforcement, while granite is extremely hard but more brittle. Using the wrong blade leads to slow cutting, premature wear, or poor edge quality.
Concrete cutting blades
For reinforced concrete, laser-welded or sintered segmented blades are the industry standard. Look for a soft bond when cutting hard concrete and a harder bond for soft or green concrete. Turbo or segmented rims improve cooling and slurry removal. For heavy demolition, combo blades with undercut protection handle rebar better than general-purpose tile blades.
Granite and natural stone blades
Granite requires a continuous rim or fine-segment blade with a harder metal bond. The diamond grit should be fine to medium for clean edges on countertops and monuments. Avoid aggressive demolition blades on granite—they cut fast initially but chip the stone and wear unevenly.
Key selection factors
- Diameter and arbor: Match your saw specifications.
- RPM: Stay within the blade manufacturer rating.
- Wet vs dry: Wet cutting extends life and reduces dust on both materials.
- Application: Slab, tile, curb, or wall cutting may need different rim styles.
