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.

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!

Drilling in a stone

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?
