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.

I am using it for chamfering a hole, at the moment there is nothing wrong, I wanted a thing with a 90 ° edge if possible

Purchased 12.5 mm. The slightest tip worn out on old concrete walls with a lot of jariy mixing? It has a simple shape as shown in the image, the shank diameter is 10 mm even though it is not throttled by the shank part It is an excellent point that it is easy to sort by a cylindrical container. Because it was cheap, it is five stars.
