I had the same model milling cutter for seven years straight. I went out and got a brand new one (flaws listed above). And the broken one, after being fixed without a bar, found a permanent home in the table. Since no other options in this price range were satisfactory, I repurchased the same model. Listed below are some advantages: Constantly reliable, never needs maintenance. It doesn't get hot as the Chinese ones do. Cons: After a few years, the precision of the jewelry's depth of penetration had failed, and it had to be fixed. My previous rod of reference took on an oval shape, and he eventually gave up on maintaining the same height. The lowest half of the silumin case cracked when I pulled it out.
