THANKS TO THEIR SPHERICAL SURFACE AND HARDNESS THEY ALLOW TO OBTAIN SHINY SURFACES. EXCELLENT FOR REMOVING PAINT, BLEMISHES, BURRS AND RUST. THEIR LOW CRUSHING DOES NOT CREATE DUST INSIDE THE SANDBLASTING CABIN AND ALLOWS A LONG LIFE OF THE ABRASIVE. THEY CAN BE USED BOTH AS A MEANS FOR SHOT PEENING AND FOR BOTH DRY AND WATER SANDBLASTING.
