Pierce a hole in a brick wall and fix the electric wire with a concrete screw there.

Although it used quite violent use, it did not cause any defects in the product, it was strong and lasted long.

There are 10 chests of cheap handmade but since the designation of the anchor you want to hit was 10.5 holes, buy a few and dare to buy → no problem so far ♪

It is used on the do-it-yourself carpentry to drill the hole of the screw hole into the block wall. Even an amateur could easily do it well.

When breaking the old Concrete Wall, I used it for drilling as a guide. Although I hit the rebar several times, I could use it without breaking or sharpness. It is not a professional, but it was cheap so I tried buying it and it was a result.

Although it is inexpensive, it is durable against the number of times of use and I appreciate it. However, if there is little lateral rigidity it is perfect.

Drilling of concrete

I bought a 3.4 mm diameter one, but the tip blade was removed by several times use. Because I think that it is not a malfunction of the product itself because I twisted the drill at the time of drilling, I intend to purchase this item next.

When piercing concrete

An inexpensive Chinese-made concrete drill which we purchased earlier was able to punch a lightweight block (strength 10N), but bent when concrete (strength 20N) was pierced 2 mm. The Φ3.5 mm concrete drill purchased this time was able to pierce 30 mm in 10 seconds and it was able to fix firmly when concrete nail Φ 3.6 mm × L 65 mm was driven.

The tip of the drill is a little longer and the whole length is also user friendly if there is a little more length.

I am happy if it comes in a case that matches the size. I bought four types, but only one was in size.
