Dril thick metal like a charm! It's good to have these in tool box. Highly recommend it !
I love these bits. So far they are durable.
Great for making sized holes.It so great that the steps are marked!
cut through metal like butter
This bit works great I see that some people may not have had the same luck but I drilled almost 20 3/4?€? holes threw 5/16?€? steel (I drilled a 7/32?€? pilot hole before actually using this bit) and it worked great made sure to keep this bit very cool with a water type of coolant so it wouldn?€?t burn up and it worked great.
