It should contain a 3/8" and 1/2" spindle notch. There were two 1/2 inch notches in the set. You have a very small flute. The handles are nice and feel strong. The parting tool provides a nice thin kerf, but HSS bends easily. The thing is just crap. I don't care since I have a tool closet. They all need sharpening, but so do most cheaper tools. I'm not sure if I want to keep them or return them.
