  This review is about the diameter: 68 mm

  It drilled through concrete slab quite easily. However, the drill guide gets stuck and does not unscrew from the cup.

  This review is about the diameter: 35 mm

  Well, they don't think that by putting the screw to tighten the drill bit, the screw protrudes and the diameter instead of 35 mm will eventually make a hole of 40 mm as the screw protrudes and will eat the wall and probably destroy the thread, so throw it all away ...
  Why didn't they put an Allen wrench Axis? (Photo)

  This review is about the diameter: 80 mm

  I made an 80mm hole with a depth of about 20 centimeters (I used the Total TAC43A13501 extension to reach across) to drain water from a balcony. On one side, there was a tile (surprisingly, it didn't break, it cut perfectly) and on the other side, concrete mixed with stone (a hard material of an old type). On the outside, there was marble. It took me almost half an hour with a powerful drill. The diamond core drill created the shape of the hole, and in areas where it got stuck, I used a needle to break the stone. The result was a perfect hole, except that when the diamond core drill came out, it broke some small pieces of marble around the hole. It's my fault since I installed a grate, and nothing is visible. It's worth its money, but I have the impression that if I had found iron rods, I would have needed a different type of core drill.

  I bought it to make an 80mm hole in the wall for the pellet stove's flue. I did it without any difficulty. And I have a small 20 euro power drill from the hardware store. Maybe with a bigger drill, it would be even easier.
