I think this drill was too wide past its cutting front point so it just spun and squeaked. It worked as a pin guage but thats not why I bought it. I bought it to drill holes, and big holes comparatively. I am giving it two stars ⭐️⭐️ because I like yellow stars⭐️ and it was fun to make the empty star outline fill up with yellow⭐️. I liked to do that but after filling the second outline with yellow ⭐️ (the first outline is already filled by Jeff Bezos⭐️) the fun was kind of predictable⭐️⭐️⭐️⭐️⭐️ and they didn't provide any other colors, unless I pretended the yellow was gold⭐️ but I am not that gullible to think such a foolish thing and like I stated previously, I like yellow stars⭐️. I don't like yellow hearts though but that is a whole 'nother conversation. ❤️What Customers Talk About
