Description: These steel hub wheels can run at a max speed of 3000 rpm, twice as fast as the sponge back and rubber expansion wheels. These are an advanced wheel type for those that are doing more than classic cabochons.

I love these wheels for doing edge work, because they are the only ones with side plating. Making hearts, Crosses, or carving V-Grooves is so much easier with these. The fine grits such as 600g and 1200g are especially good for this as they make nice clean lines without chipping. The Steel hub helps the finer grits cut. Because even though the particle size is fine, the corners will remove stock much faster than the face.
