Took too long to receive 🙌.
The center bit is too short.
I ordered a new one when I got home the one I ordered was there.
Now I have to figure out how to cancel new order.

Use this to bore holes in all sorts of walls. We wear them down to the nub before replacing it. We can usually bore 3 to 4 holes, sometimes more, before replacing it.

The bit went through a brick layer and then the center (braced) section of a CMU (cinder block) pretty easily in about 15 minutes. Looks like it should be good for at least one more hole but for the price of it,I’m happy with the purchase.

Works well, used to drill line set holes in brick and block for Mini-Split units.
