Lance Davies (Spanish Fork, UT)

Big blue demo blade worked awesome cut through shingles nails and everything else without even slowing down.

Joe Bechtold (Wheaton, IL)
Great Blade

I found this 5-tooth blade far superior to any other blade I have used for demolition. In this case I used the blade to cut through three layers of shingles plus plywood roof sheathing all in one pass. This heavy duty blade cut through cleanly in one pass and made quick work of the task at hand. You need this blade in your tool box.

Bruce Lord (Hastings, MI)
Roof Tear off

This blade worked excellent. It cut through shingles and OSB like butter.

Tom Bray (Austin, TX)
The only thing that worked on an oak stump

After an encroaching oak tree was cut down I had the task of removing the stump. After dulling chainsaw and regular saw blades and being unsuccessful with an axe, I bought the 5T demolition blade. It kept cutting even after hitting rocks and pebbles in the stump/roots of the tree. I only had to stop to let the electric handsaw cool down before continuing. I highly recommend it if you're going to be hitting anything besides wood.
