KSEIBI 619578 Water Swivel Adapters for Wet Core Bits, 5/8"-11 Female Thread Diamond Wet Core Bit Adapter, Well Water Drilling Equipment for Core Drilling, Water Well Drilling Equipment

Works great, I’ve used it for a few cores so far, small ones around 1” - 3” diameter and 20” thick. I got a different hose to make it longer, the included one works just fine. Plenty of flow if you have the pressure at the water source to shoot cores out. I blow the water out of it with an air gun after use and wipe the threads clean.

I welded a 1" pipe coupling on the end of this swivel so I could use regular pipe to bore under a roadway. I also used an SDS max adapter on the other side so I could use my rotary hammer to drive it.The swivel portion worked great, held up, and didn't leak.The hose clamps are the worst and blew off repeatedly until they just stripped out. Not a big deal, but it is frustrating to have to source some quality hose clamps (I used fuel injection hose clamps) when you are trying to get something done.

Gets water to your core drill bits. Heavy duty. Great value compaired to buying a whole core drill.
