For marble PY plug driving

With the concrete drill, we purchased this product because there was concern for cracking as we drilled a hole in the marble, but the drilling work was finished cleaner than expected.
Drilling of hard tile

I bought the same thing because I was in good condition as I borrowed it to a craftworker in the field.
A hole opens quickly, such as a tile that took a long time to open.
I have used a diamond type, but this is good!
Drilling work on tiles

I used it to open a hole of 7 mm to the porcelain tile. With a carbide metal drill, it took about 3 minutes per hole, but I could drill in about 30 seconds. I am amazed by the difference in performance. It is good to use the guide because sitting of the drill at the beginning of opening is bad.

Compared to tile drills, drilling work was quicker and durability resulted in cost reduction as a result.

I used a variety of drill blades but I was in trouble without holes. A hole was made easily when using a diamond drill.
Ceiling concrete drilling

Since it is a hexagonal shaft, it is easy to attach to and detach from the drill, it does not spare and the center chips are discharged from the side, so there is no clogging in the center hole. Also, if it is a concrete drill, it does not advance at all on the way, but since it is a diamond, it may take some time but you can drill to the required depth. Drilling on the ceiling is difficult to replenish, and chips and mud will fall, so please make something good jig.
