Отзыв о KATUR Алмазная фарфоровая керамика, диаметр. от Dave Stewart

This hole saw's cheap construction and lack of durability make it a poor choice for industrial and scientific purposes. The only positive is its low cost, but that comes at the expense of quality. The blades dull quickly and the porcelain ceramic material feels brittle and prone to cracking... Spend a little extra for a more reliable tool..
