Review on 🔪 Disston E0211330 4 Inch Bi-Metal Blu Mol Blade by Aaron Vang

These bits last a very long time and fit through stainless steel and chrome pipe with ease, just remember to cool them! For stainless steel I use plain old water with a spray bottle. Just remember to keep it cool and use the right pressure, they last a long time and the price can't go wrong It's M42 cobalt steel construction.
