ENDURO-FLEX outperforms all competitive flap discs thanks to its innovative design and refined zirconium grain. Our exclusive ECO-TRIM™ backing can be easily trimmed back to expose fresh grains and extend disc life while absorbing vibration for unmatched comfort during removal. MAX LIFE cold cured glue ensures the freshest abrasives possible by eliminating the need to apply heat to the disc during the manufacturing process, improving consistency and maximizing disc life. ENDURO-FLEX is the longest lasting flap disc in the industry and removes more material than any competitive flap disc. Your employees will spend more time getting the job done and less time making trips to the tool crib, saving you time and money while maximizing your productivity.
