Surprisingly easy to core 14" horizontal holes in older concrete. Makes a mess - as expected. The speed and torque seem appropriate. You still need to lean in on a 2" bit, but it probably took 15 minutes or less of not that difficult of labor. A vertical hole in a slab would have been much easier. The plastic parts of the drill appear to be good quality, except for the water adapter that needs some fiddling. The bit abrasive seems like new after at least 30" of drilling, so it looks like it will last quite a while. Overall, a good deal, especially compared to any alternatives.

I purchased bit to do a core bore for a hot water heater exhaust to drill through 8 in thick solid concrete walls. It worked great. Have drilled 7-10 holes with it.

The bit cuts slowly, but it does eventually cut. Unfortunately I can also attest it will cut thick steel cables, as it cut a post tension cable in my patio. Fortunately there was no damage done.

What is the outside diameter of the bit where it connects to the drill? I’m wondering if I can use an extension with the 1” bit to drill more than 14” deep, but need to know if the entire bit can fit through a 1” hole. Thanks!
