I had a milling cutter that I had been using for seven years. 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. Paid for expert help: Does what it's supposed to do and doesn't require maintenance. It doesn't get hot as the Chinese ones do. Distinct drawbacks: After a few years, the precision of the jewelry's depth of penetration had failed, and it had to be fixed. He ceased maintaining the height when my previous guide rod, which was round, became oval. The lowest half of the silumin case cracked when I pulled it out.
