Because of the thread on the shaft I wanted to deduct a star or two. They were wound diagonally and my turn would not start without trying to cross the thread. I was ready to return it but decided to have it repaired. Luckily I started threading right after beveling the end and got a good inch of thread so all is fine. The cutter itself is very good and holds a left-handed 3/8 cutter very well. It works flawlessly and makes a very smooth cut. The balance is very good at 900 rpm on my Grizzly G0705. I am very happy.
