What do you think about carbide tool? Are they good to start with
Yes and no. Like everything in woodturning it’s a trade off.
@john lucas has some nice video on using carbides.
I use a #4 Hunter a often on but not on bowls or hollowforms.
The carbides are easy to learn with. You don’t need to sharpen them
The traditional gouges in most situations remove wood faster and leave a cleaner surface.
In general you need more carbide tools and they are expensive. I can turn a finished beads I can sand with 320 with spindle gouge or a skew. Turning a bead with carbides you need a point carbide to cut the groove on the sides of the bead and a square or round to shape the bead and you probably need to start with 180 or 220.
For roughing bowls -Carbides are harder on the body and I think harder to make nice curves with.
A bowl gouge the tool does the work being held lightly in the hands
Where it can be used the hunter can leave a fine surface- I use it as a finishing tool for boxes and goblet cups.
I know a turner who lacks the range of motion to use gouges well, does incredible work with carbides.
When he did a demo for our club he used 6 or 7 different carbide tools to make a piece i use 4 tools to make.
It’s your choice. But sooner or later most carbide users want to switch to gouges but keep the carbides for some jobs,
