Welcome!
If you are new to using a lathe, it might be better to practice on some steel to start with.
You can see the effect of grinding tools in different ways, and shapes, and learn about speeds and feeds before you make a mistake and scrap off an expensive casting.
It can be a useful learning exercise to make a few simple tools before launching into a costly kit of parts.
You will always find things like a Centre Height Gauge, Tap Wrench, Tailstock sliding Die holders, ditto Tap holders, Mandrel Handle, etc useful in years to come. And you will have gained useful experience in making them. (And if there is a false cut, or poor knurling, it may not look too good, but it will still do the job, and you will have learned from it. )
