Buying Guide: Key Considerations When Choosing Masonry Blades
What blade material fits your project? Diamond blades excel in grout and concrete work due to durability and clean cuts. Carbide blades offer cost efficiency for lighter grout and adhesive removal. Choose diamond for tough materials; carbide for quick, light-duty tasks.
Which blade shape matters? Flat blades reach straight grout lines; curved and crescent blades access corners and irregular gaps. Consider whether you need replacement easily in tight spaces.
What kerf and thickness do you need? Thinner kerfs (around 1.6–2.2 mm) minimize tile damage and allow precise edge work. Heavier-removal needs may require slightly thicker blades but can risk more material removal.
Blade life and tool compatibility: Look for blades advertised as longer-lasting or 5x longer than carbide equivalents. Ensure compatibility with your oscillating tool brand and attachment system.
Access to tight corners: If your job involves tight alcoves or recessed areas, a flat-side or low-profile design can improve reach and reduce the need for extra cutting steps.
