Review on 🏗️ Ultimate Concrete Masonry Set: Carbide Diamond Suitable for All Projects by Edgar Gomez

These drills look good and drill effectively when intact; but the ends are frayed. Smaller bits only go through a hole or two. Bigger bits last longer. These bits are inexpensive, but it's best to look elsewhere and buy from a reputable manufacturer of durable masonry bits. You seem to get what you pay for.
