These are 6” carbide grit sawzall blades. I’m selling a lot of 25 for $75.
These are great and a must have for demo projects. Plaster, Lathe, Tile, Grout. Brick, Block, and much more.
Fiberglass tubs are a breeze to demo with these blades as well. These go for over $5 per blade on line and in stores.
