Very pleased with its performance and durability. Drilled at least 12 holes 12”-16” into newer concrete like butter. No complaints. Would buy again but don’t believe I’ll need too.

Ordered this as a replacement for a bit not like this for a bit of my friends that I broke drilling through hard rock. My friend's in concrete and excavating and he received this from me as an upgrade and he loves it!

I like the four cutters and the sturdiness of the drill bit.

Works great, I drill reinforced concrete with a standard hammer drill bit until I don't make progress then I put this one in. I could use it from the start but if I don't hit rebar I don't need the four flute. When starting with this bit I run it at low rpm until it seems seated in the bottom of the old hole then I open up. As the video on youtube shows, don't increase pressure on the bit because progress has slowed. Like drilling steel when the bit breaks thru it will catch on that big burr on the back side of the hole and jerk your wrists, another reason not to lean hard on the bit.

Its nice when a tool does what it is supposed to do. I needed to cut a hole through an 8” foundation wall and my carbide bit hit rebar and stopped progressing half way through. I ordered this bit and after chewing through the rebar it went through the rest of the concrete like butter. Go slow when you hit rebar or it could grab, twist your drill and do a number on your wrist. Because of the time saved I intend to use this bit whether I suspect rebar or not.
