DI*** Do not set drill in the trigger lock position of drill. If the bill jams the drill wil kick back from the torque.
Wet 50mm
I got this coring bit to drill out concrete pavers to pass conduit. The drilling was horizontal and cut thru easily as a wet coring bit and performed much better than dry bits. It still required direct pressure from physical strength and leaning into the drill. This is hand drill without a drilling rig. I was very pleased with the coring and the smooth hole when finished.

Joe V Works well wet or dry
Wet & Dry 108mm
Phenomenal core bit it did exactly what I needed it to do. I had to drill through 18in. of brick and stone mortar and it did it flawlessly. The only problem I had was using M18 FUEL 18V 1 in. SDS-Plus Rotary Hammer it didn’t have the cohonaes to do the job. So I had to bring out the big daddy M18 FUEL 1-3/4 in. SDS-Max Rotary Hammer. Then the bit went through with ease.

Wet & Dry 100mm
Good drill bit , but you really do need a large drill to use with it. A standard hand held drill / hammer drill will over heat quickly when drilling concrete 🙄🤷
