Review on 🔧 SabreTools Carbide Concrete Edition by Oscar Ferrell

I needed this drill bit to drill a hole in a cinder block and hold a 3/4 inch pipe with wiring. The cinder block turned out to be filled with concrete, and I figured the brief hammer job turned into a 15-minute gnashing of teeth. Most pieces of concrete fail after a few inches of concrete, but this one held up like a champ through 8 inches of concrete.
