Frequently Asked Questions 

Can one demolition blade really cut through both steel and concrete effectively?

Yes. Our demolition blades are engineered to do exactly that. The key is using a bond and diamond segment geometry that handles both abrasive concrete and hard steel. Many users report one blade replacing multiple specialized blades when matched properly

Does the blade life suffer when cutting mixed materials?

It depends. Blade life will still depend on feed rate, saw power, material thickness, reinforcement, and whether you’re cutting wet or dry. Reduction in change-out time often offsets any slightly lower life per substrate because you’re eliminating blade-swaps.

Wet or dry cutting — which is better for demolition blades?

Both are supported in many models, but wet cutting is generally better when dust, heat or material loading are concerns. Dry cutting is useful for portability and quick job-site use. Always check each model’s rating. Call us and we’ll walk you through it.

How do I choose the correct blade size and arbor for my demolition saw?

Make sure the blade’s diameter fits your saw’s capacity, the arbor/hub matches your saw’s arbor size, and the blade’s maximum RPM rating meets or exceeds your saw’s output. Using a blade outside its rated specs can reduce life or cause safety hazards.
