Ok, só depois de trabalhar uma vez é que poderei dizer algo acerca do aço e do diamante

Version avec découpe sous eau, cela rentre sans forcer dans mon lit en pierre.

Bit is a light weight heavy duty enough for cutting. Threads match the hand held drill great.

It works great drilled in some posts holes into bedrock. Can put it in your normal drill, I use that hammer drill which is not recommended for coring holes.

Worked well on drilling 8" reinforced concrete. No blow out on the other side of hole

Bonne couronne pour des travaux occasionnels

C’est très bien, je suis content

I’ve purchased this tool to install a mini split AC system in my garage through a block and concrete wall, although the work was done, I ran into some difficulties with the pilot bit, the adapter I used was the SDS-plus and the pilot drill bit to do a pilot hole through the wall, the bit is attached to the adapter with a side screw that lands on a flat side of the bit, the problem was that with the vibration the securing fastener always came loose no mater how tight I tried to secure it, I ended up using a different drill to make the pilot hole and once assembled together with the barrel was a little better but still managed to get loose several times, if the drill bit came with a notch for the securing fastener to land instead of a flat surface probably there is a better chance of keeping in together. Overall, got the job done with some hiccups

It does the job. I drilled a clean hole through 2-3 inches of brick to feed my hose through the wall. Maybe it was user error, but with the guiding pilot bit in, the main core just wobbled around way too much to bite into the brick. So what I did was cut out a small hole in a piece of plywood, then anchored that into place and used it as a guide. No issues after that, it just took a while. The hole was very clean. I then threw a pipe and 3D printed an escutcheon.

I needed to cut two holes in the concrete floor for a toilet and shower drain. Floor thickness about 4 inches, and super solid, 75 year old concrete. This drill did the trick. My only precaution is that once the main circular bit starts getting a bite on the concrete, REMOVE THE PILOT DRILL!! It's pretty tiny and deflects easily, so it will follow a different path than the core drill, and will likely break. Also had to take a break about every inch or so and chisel out the core.
