Robert Sorby Midi Multi-Tip Hollowing Tool

Smaller than other hollowing tools, its small scale makes it ideal for smaller hollow forms. It has a 1/2" flat surface that offers more control than a rounded shaft wold offer. Its swivel clamp allows under cutting, with any of the included cutters:

1 x Curved tip (RS111C) for flowing shapes
1 x Pointed tip (RS112C) for square shapes
