Working on soft materials and wasting your inventory of abrasives. Look no further. NetGRIND is not only your answer to this problem, but it will save you time and money. Welders and fabricators perform grinding on aluminum and other soft materials for many reasons, whether it is pre-weld surface preparation or post-weld bead removal and/or finishing. Compared to other metals, aluminum has a much lower melting temperature, so it melts easily. Our NetGRIND NON-LOADING FLAP DISCS are your solution. NetGRIND disc cloth is layered providing a cushioned substrate that results in heavy stock removal rates and surface blending action. When grinding with NetGRIND the surface stays cooler and avoids burning due to the net abrasive structure of each individual flap that resists clogging on soft materials. Available in 40 and 60 Grit, 4-1/2 x 7/8 and 4-1/2 x 5/8-11, Max Force Performance Tier.
