Rated 4 out of 5Â by Smith808 Works fine
Bought this to use on my Dewalt core drill which has a 1/2" male threaded chuck. Most standard core bits are 1/2" female so this extension worked fine. These extensions allow for the use of an A-Taper pilot drill bit (again, standard core drill stuff) Some cheapo TCT core bits come complete with SDS adapters which have different threads to this product and wouldn't be compatible.
Feels robust enough and the threads were fine.

Just what i needed for a very thick wall. Good fitting thread on my SDS arbor.

Rated 1 out of 5Â by Bravosierra39 Doesn't fit all core drills
I bought this to extend my Titan Core drill set. It does NOT fit. Different thread and no way of locking guide drill.

Without this item the job would be impoible to complete. It did not lock up at the point of dismantling, very helpful.
