Worked better then some high end bits I have used. Drilled a 5 in core with no issue or hiccups including 2 -1/2 rebars definitely shocked how good it worked for the price I didn't have the best expectations. But I was wrong
It is well made, ate up the concrete slab using a wet core drill. We went with a handheld model, which works great if you have a lot of experience with large drills.
Came promptly and worked great. Considering most of these bits cost over $100 I was curious how it would do. Had to drill two holes through brick veneer and cinderblock foundation and it worked great. I definitely recommend this bit.
