Отзыв о Босх CO2142 3 7 Кобальтовая сверла от Cody Henry

After I put it to the test with tough, heavy-duty materials, this drill bit failed to live up to its advertised strength and durability. Though it appeared to have A promising design and construction, it quickly wore down and required constant replacements .The lone positive is that it is affordable but it`s not worth sacrificing quality for a low price. As a hesitant buyer, I cannot recommend this product for any sizable Industrial or Scientific work..
