- Framing
- Ripping
- General purpose
- Decking
A budget everyday framing blade to stock in quantity when you value low cost over the longer life of a premium Diablo.
Pros
- One of the cheapest carbide framing blades, easy to keep several on hand
- 24 ATB teeth handle everyday framing, ripping, and deck cuts without fuss
- Silicone coating cuts pitch buildup in pressure-treated and resinous lumber
Cons
- Standard 0.071 in kerf draws more power than a thin-kerf blade on cordless saws
- Carbide dulls faster than premium blades, so it is more of a consumable
- Rough 24T finish and no nail-rated grind make it a poor demolition or finish choice
