These CRL Corner 25/32" Nipper Glass Pliers cut a round corner into the square cut corner of 1/8" to 1/4" (3 to 6 mm) glass or mirror in one single "bite". When properly positioned, the hardened carbide steel jaws easily remove glass and leave a rounded edge. Light grinding with a belt machine is all that is needed to finish the corner. Automatic internal stops prevent the jaws from ever touching. A removable spring holds the jaws in the open position on this 10" (254 mm) tool so they are always ready to use. Great for desktops, shelving, partitions, displays and wherever else a round corner is needed. They are an exciting addition to any glaziers tool box.
