WALTER TECHNOLOGIES 08L450 Alu™ Grinding Wheel 24 Grit 4-1/2 in Type 27, Depressed Center 7/8 in

These wheels grind all types of aluminum and non-ferrous metals smoothly and at removal rates never thought possible. The specially impregnated bonding of these wheels resists loading even when grinding very soft, pure aluminum. They do not contain any waxes or lubricants and do not contaminate the material worked on - ground surfaces are therefore clean and ready for welding without further clean-up. Fast removal rate. Long wheel life. No clogging in any type of aluminum.
