Review on GBJ Indexable C25 25 150 APMT1604PDER Machining by Patrick Arnautov

I bought this because it came with 10 earbuds which I found very cheap. It arrived and I realized it had a 25mm stock and my R8 only fits up to a 3/4 so I ordered an R8 7/8. When the 7/8 R8 arrived I threw the end mill on the lathe, cut it down to 7/8 and split the shank length in half because the 7/8 R8 only allows the shank to go in about 1.5 inches. It worked great because it cuts through steel like a hot knife through butter.
