Blue 46 grit roughing wheel that fits Pro Sharp machines.
This wheel is a perfect combination of bond and blend for an aggressive cut. Keeps the radius but will have a very coarse grind removing more material. Shouldn’t be used as a finishing wheel
Excellent wheel for new blades having a contour or radius put in. Also excellent for skates that have rust or blemishes from not being used in a while.
This grinding wheel is compatible with Machineskan
