I had to cut hardened nails driven into a terrazzo floor over a concrete base. They could not be pulled and had to be cut flush with the floor. At first I tried using bi-metal cutting blades, but they dulled after a few minutes. So I ordered these carbide and titanium blades to get the job done. Thinking carbide was harder than titanium, I tried them first. The carbide blades got the job done quickly. I had to cut and remove 15-20 of these hardened 30 gauge nails. It took two blades to work, but everything went smoothly. For softer metals like aluminum I suspect bi-metal blades work well, but for harder metals carbide is better. The titanium blades had a slight ripple on the teeth, like a hacksaw, and arguably worked as well or better than the carbide blades. Maybe I'll try them first next time. These giant tunnel boring machines use carbide, so I knew they were nearly indestructible, which is why I chose carbide blades over titanium.
