Review on Power Through Tough Materials with Milwaukee 49-56-9290 HAWG Carbide Teeth: A Game-Changing Tool! by Jared Coleman

This is an amazing set of hole saws. Recently a 70 year old house underwent a complete renovation and they worked great. Cutting is much faster than with a conventional hole saw. The only downside is that they are very aggressive. So if you try to drill into softer materials, your teeth will bite. I drilled through a plastic bulkhead water tank, it worked but wasn't ideal for the job.
