Review on 💎 Maximize Precision and Performance with Champion Cutting Tool CT7 3 Tungsten by Calvin Chavva

I was very impressed with how well this drill bit cuts through metal. It's like a video. Use enough cutting oil and it will last a long time. I made over 30 holes in 1/4 - 1/2 inch steel plate and the last hole was just as easy as the first. I wish I had more of these bits than the two sizes I bought.
