Customer Reviews for VEVOR Dry Core Drill Bit, 4.25"/108 mm Diameter 5/8"-11 Shank Arbor with a Pilot Bit & Blade, 9.5"/241.3mm Depth Diamond Coring Bore Tool, Masonry Hole Saw Bits for Hard Concrete Brick
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.
