Review on EZARC Titanium Oscillating Multitool Blades: High-Speed Power Cuts for Wood, Metal & Hard Materials - 3-Pack by Brian Gordon

These extra long blades I needed to cut the outside edge of a rotting window sill 1-3/4 inch thick. The extra length worked great. through about 30 linear inches of sill with a blade and it still has life. But the yellow "Titan" coating is already erased. I still doubt it will do anything. When you paint something white, it technically has a "titanium" finish because the white color is due to titanium dioxide particles. Anyway, I found that the teeth had a direction so that if I moved the blade in the same direction as the teeth, the blade seemed to cut through the sill faster. I might try carbide teeth next time to see how long they last, but for now these extra long bi-metal blades are good for working through very thick material or hard-to-reach places.
