Love these blades for cutting through old roofs to set HVAC curbs! … Hot knife through butter I say, with NO gumming up the Saw. I still can’t believe it and I was the one using it! Every HVAC & Roofing Supply House should have these blades!”

Save time removing commercial and residential roofing materials
- Cut in tight spots where commercial cutters will not fit (under conduit, around makeup air units, and near roof edges).
- Cut commercial roofing materials without a heavy roof cutter (cut in curbs, small repairs, or maintenance).
- Cut openings for air conditioning units and skylights.
- Cut modified roofing into sections (faster than utility knife).
- Cut multi-layer shingle roofs into sections for easier removal and quicker clean up.
Durable & Long-Lasting
Everlasting carbide teeth with extra-wide kerf.
Cut through extremely dense and gummy materials without chipping, warping or cracking.

Clog Free. Bind Free.
Massive gullets provide space to remove debris and reduce friction to keep the blade spinning.

Saw Compatibility
Fits 7-1/4″ circular saws and worm drive saws.
How to remove diamond twist out
- Place blade on hard surface.
- Insert screwdriver through arbor.
- Apply downward force on blade and screwdriver.
