[stone] coloured burs

[Andrei Stefanescu]

Hello all,

I have seen a Dremel-like set of burs. They come in
three colours: white, pink, and grey. What do they mean?
And what specific use do the various shapes have -
conical, spherical, cut-off cones, etc.?

Is it worth buying the set (it is quite inexpensive)?

Thanks and regards,
Andrei
