Mark H. Smith, MNV Holdings LLC

We were amazed at the performance of BigBlue™ demo blade as it never slowed down, never gummed up, and didn't even notice nails. Cutting speed was faster than anticipated. I will definitely keep BigBlue™ demo blades in my arsenal going forward and wouldn't hesitate to recommend it.

Tony Montgomery Tony Montgomery, Montgomery & Sons – Orion, Michigan

“BigBlue™ 3T worked better than any blade we have ever used for demolition. It took 10 Marathon blades to do the work of one BigBlue™ and BigBlue™ is still going strong.”

Mark Espeseth, Woodruff, WI

I am flipping an old house that has several layers of sub floor. Everything from rough cut to plywood to asphalt. I was at my ends wit trying to find a way to cut through it without buying numerous blades. The BigBlue™ not only cut through it but, it was fast! Best thing I have ever used, I was cutting through at least 1 1/4 inches of wood, nails and asphalt and it cut as fast as I could push the saw. Awesome product, very grateful to have found this blade. I would strongly recommend it.

“The BigBlue™ 5T cut through nails and all like butter. What took an entire day with a Diablo Demo Demon only took two hours with the BigBlue™ 5T.”

  • What is the difference between the 3T and 5T?

    BigBlue™ 3T is great for roofing demolition. It is better for cutting the thickest materials that tend to gum up. It will cut tar and gravel, multi-layer shingles & nails, cap sheet, ice shield, galvanized metal, and much more!

    BigBlue™ 5T is great for general demolition. It is better for cutting a combination of materials. It will cut through multi-layer shingles and nails with wood roof deck, plaster and lath, wire mesh, many flooring materials, cap sheet, ice shield, decking (to create larger gaps between boards), galvanized metal and much more!

    Absolutely not! BigBlue™ Demolition Blade is designed with oversized gulluts that eliminate clogging and keep the blade cool and spinning at maximum revolutions.
