after repeated use of this tool is, I regret to say that this money be better used in more high-quality tool set. The bits are processed not one hundred percent, some are still standing on the edges so that it easier to work is impossible, the gun is the supplied is all well and good but you would be able to save. einzigst the good thing about this tool set is the extension and by far the most robust aluminum case
I personally would not buy me a second time this product,
