Used 3 of these to core through 42 inches of concrete. Perfectly straight hole. Do not settle for a knock off. Great quality!!!

Paired this with a 3/8” drill adapter and 2.5” diamond core bit. Worked great. Love it.

I used three of these in tandem for an extension and it worked quite well for my project.

The extensions are a bit heavy, but the hex fittings on each end are amazingly useful for easily disconnecting sections. Extensions were straight and threads easily attached and removed.I would buy this again
