Broke on first use
Adapter twisted off within the first minute of trying to drill a 2” core bit hole in green concrete

What a DISASTER!
Bought a new rotary hammer drill ($150), a 14" x 3" concrete drill bit ($90) and this $39 core drill bit adapter. I was 10 minutes into my first hole, about 6 inches, when this cheap adapter broke off inside the arbor of the drill. It's next to impossible to get a 1 inch broken bit that is jammed into the arbor out, thereby effectively ruining my new rotary hammer. Not happy! I would like to say DO NOT BUY this adapter but there are few alternatives for a 1-1/4“UNC Thread Male to SDS Plus adapter. Home Depot lists one from another brand (eDiamondTools) but it will take several days to receive it, further delaying my job. Oh yeah, it also took me 30 minutes using a heat torch and large wrenches to unthread the broken adapter off of the drill bit.

Twisted and broke the end off inside my drill.
Used for less than 20 Minutes and the tip twisted and broke off inside my drill exactly like another reviewer experienced. My drill has a clutch to limit torque so this shouldn't even be possible.

Stay away
Very cheap steel. Went through 3 to drill 5" x 8" thru concrete wall. Maybe ok for small jobs. All the shanks bent, very frustrating.
