The quality of this so-called "industrial and scientific" bit is below average. My analysis of this product showed that it had poor durability and quickly lost its sharpness. The only pro is that it was able to drill through concrete initially, but even that was not impressive enough to justify the price. On the other hand, the cons include the fact that it becomes dull quickly and isn't very durable. I would not recommend this product to anyone needing a reliable concrete drill bit.
Pros
Efficiently grinds and polishes concrete surfaces for a smooth finish.
Cons
May cause excess dust during use, requiring proper safety gear and ventilation.
Both tips will wear out in minutes when cutting through a normal concrete slab. And it says he'll cut through the rebar, but that's even remotely impossible. When we hit a piece of rebar, one broke and damaged the other. Not recommended.
I wanted some data here as it is missing and Revain is tying the wrong accessory so it can be attached to the drill press. If you buy this beat or something similar from Toolocity (btw, great answer from this company if you have any questions). buy this part if you buy this bit to drill additional holes for my Max Jax to mount the lift somewhere else.
