• Extend disc life – More power to go the distance with discs that can last 2-3 times longer than traditional no-hole, 5-hole or 6-hole discs.
• Increase productivity – Longer-lasting discs improve productivity and the unique multi-hole disc pattern is designed for quicker changes because hole alignment is not required. You’ll see the difference in material consumption – and your bottom line.
• Clear out more dust with less disc loading – The spiral-patterned disc design features hundreds of holes to give dust a better escape route, moving more dust away from your finishing surface without loading the disc. Dust settles into the loops of the disc, and not in the air or on the disc surface.
• Improve cutting ability – Premium abrasives deliver consistent performance to get the job done … and done right.
• Simplify disc application – Discs utilize the 3M™ Hookit™ Attachment System for easy reuse.
