Drilling in concrete wall
On 2018-07-30 15:00:44
Because drainage became impossible even after cleaning with drainage pipe of air conditioner, we opened a hole to newly drain drain pipe to reinforced concrete building. The thickness of the wall is about 15 centimeters, but I have opened a preliminary hole with a vibration drill, so the penetration time with this drill should be 10 seconds. Hammer drill is rented at a nearby home center. There are no future plans to use, but as expected it is made by Bosch. Awesome sharpness? .
Drilling of concrete foundation part

Used to drill a hole in the foundation of the house to pass through the fuel pipe of the pottery kerosene kiln. I thought about renting a hammer drill, but I borrowed a drill from an acquaintance and bought a bit. We were able to empty the 160 mm concrete foundation at once. It got cheaper than renting. As expected is BOSCH.

Especially, it was possible to use it without problem. Since the number of times of use is still small, the condition of wear and tear is unknown.

Sharpness is very good at first, but it gradually falls. Please display the rotation speed that was consistent with the strength.

I pierced concrete about 100 preliminary holes, but it worked without problem. I hit the rebar, but the drill was nothing. I can still use it.
