These grinder pucks are hand savers! When grinding down glass, use the puck to push and maneuver the rough glass around against the grinder bit and protect your fingers from the sharp glass edges. The grinder pucks have one flat side, a convex side and a curved side for different angles and movements along your glass.

Only one grinder cookie is necessary but two can be extra helpful in protecting your hands and providing stability to a piece when grinding.

TIP: Try to hold the glass down with light pressure from one finger while pushing the glass against the grinder with the puck taking all the pressure off of your fingers.

NOTE: Listing is for a set of two grinder pucks. The colour of the item is based on availability and may not be the same each time or as shown in the photos.
