A part of the review has been auto-translated.
great tool to do small holes in concrete with no damage...you must use water to prolong the life for this tool...overall I’m ok with it.
finally received after 40 days...price is good but looking at the thickness of the cutting surface (very thick)it will take time to cut a hole in a concrete...I have several other brands which are thinner and performed excellent...time will prove its quality.
This is the second one o purchased...the first one was ok, this one had one cutting surface longer compared with the other two making difficult to cut the concrete...all three surfaces must be same length in order to do the work properly.
very good
