Отзыв о STARVAST Би-металлические положительные резцы для резки волокнистых плит от Chris Lloyd

I purchased these hole saws for an industrial and scientific project and was extremely disappointed with their performance .The saws were dull and struggled to cut through even the thinnest materials. The one pro is that they do come in a variety of sizes, but the cons far outweigh this small benefit. These hole saws are a complete waste of money and i WOULD not recommend them to anyone in the cutting tools industry..
