Exterior wall construction

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.

For saddle attachment to the concrete wall, by repeat purchase, low price is saved for strength.

Although the body may not be easily broken, it is slightly flexible and easy to bend.

It does not become usable at all. It is useless at about three holes. I bought ten books but I threw it out of six.
