What can I say assuming the R8 is shaped right it's nothing special. There are obvious sanding marks and the finish is pretty poor but it should work and for the price I wouldn't expect more.
Exactly what I needed. Stable with four set screws and the cone is tight even before it is screwed into the drawbar. Don't have the infinite patience to build your own ( I'm looking at you old Tony), grab this and some HSS footage and start cutting.
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 Grizzlyβ¦
