For pilot holes to concrete
On 2018-08-12 17:18:40
I bought it to open a preliminary hole when screwing to the concrete surface. It is cheap, but it works properly. This was enough, as I will not use it many times.

Although it is used for the drill hole of Viscone, it has at best only mortar or block, is not it? Although concrete can be newly built, the building with old strength is tough.
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.
Anchor's pilot hole

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 ♪
Drilling into the block
On 2018-04-28 15:58:23
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.
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
On 2018-03-12 15:51:34
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
On 2018-02-16 15:41:12
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.
