Drilling of stone

It seems that there are variations in the super steel part depending on the product
COSPA is good.

We are using it when setting fulcrums at rocks. Performance is inferior to HILTI, but because COSPA is good, you can dare to use it especially when drilling into a hard rock with its tip easily burned.

I bought it as a spare. I do not use it yet but I think that it can be used normally.

You can rest assured that Miyanaga's drill blade has been used until now.
Treatment of rocks in parking lot

It was more effective to use the hammer drill every two seconds, every 10 seconds, rather than using only one expensive bit to drill a hole in the rock when using the cellar!

I used it in jumping, I could dig a hole easily with a hard rock

The triangle of the tip helps to drill in the correct position.
Drilling in a stone
On 2016-12-15 21:04:33
I am satisfied that I can drill stones and concrete without difficulty.
It is planned to be used in foundation construction etc., but the purpose is not the original use, so it was not good.

I have found the original used product, but have you not used it much recently?
Drilling in a garden stone
On 2016-04-25 18:21:46
I used it for the first time, but the hole opened smoothly than I thought.

Hole drilling for granite marble concrete hard tile for 5 mm plug

Concrete is good without problems. Stone is draining while pouring water while putting water in a cup or the like while chilling. There is no problem separately.

It is used for drilling concrete, and sharpness is not bad, but it broke with several times use. Improvement in durability is desired.
On 2015-06-06 21:44:29
It has no durability at all. The tip tends to peel off. I wonder how many books I've already bought
On 2015-04-16 19:39:18
The sharpness is quite good, but the part other than the tip <Tungsten> can break, so I want durability.

For dismantling of garden stone (drilling of Seriya)
On 2015-01-11 17:14:21
I use it along with the arrows for disassembling the garden stone, but I think that it is a good product for a long time as well as a hard stone.
On 2014-04-16 21:27:28
I use it for drilling a tile. At first it is good, but it seems that it can not be used for a long time.
Drilling of stone

Best of the products used up to now. The opening speed of a hole in a stone is different. Since I have just used it, I do not know the durability but I am very satisfied.
Stone material Seri drilling
On 2013-06-14 16:45:48
Although I am a beginner, I have drilled a hole of a seri in a hard stone with a hammer drill. As of now, there is neither wear nor lack of the blade and it is smooth. There are times when the hammer drill is turned when the bit passes through the stone, and the hand hurts, but is this how I used it bad?
