✅ BladeGuy Pro Tip
Walk-behind saw performance depends heavily on the diamond blade you run.
Use the correct blade for the material:
- Asphalt → asphalt blade with drop segments
- Concrete → hard bond concrete blade
- Green concrete → softer bond blade
Using the wrong blade can slow cutting speed and destroy segments quickly.
