On 2018-08-27 19:31:37
We bought referring to the fact that it will last from 1.5 to 2 times this time because we have to do a lot of drilling work with a depth of 35 mm, but we purchased a conventional concrete drill (50 holes with 2 bladed carbide specifications Although it was made, this bit was in a state where it could manage to open something in 25. It is regrettable that it is a lifetime proportional to the price.

Would not it be Delta Gonbit if I thought about drilling firmly with vibration drill? Durability, hole system and satisfactory in everything.

When opening a hole, since the tip of the drill has little blur, it is easy to work. I am satisfied that a clean hole will open.
