PFERD Expands Range of POLIFAN®-STRONG, Leader in Aggressive Metal Removal, to include 7” Diameter

POLIFAN®–STRONG Flap Discs feature a major design innovation that allows the removal of more material in less time than any other consumable abrasive tool used with an angle grinder. Available for 4-1/2”, 5”, and now 7” angle grinders. The higher power output of 7” angle grinders is ideal for POLIFAN®-STRONG performance.

POLIFAN®-STRONG is manufactured with 36 and 50 grit zirconia, with 7/8” arbor hole, or 5/8-11 quick-change hub. The 36 grit version is intended for rough surface grinding and weld removal. 50 grit is engineered for chamfering, deburring and edge work.


The new POLIFAN® STRONG SG-PLUS flap disc removes more material in less time than any grinding wheel or competitive flap disc on the market.

The patented construction of the POLIFAN® STRONG flap disc provides extraordinary stability previously only found in reinforced grinding wheels. The extended flap length allows for continued aggressive grinding up to the last grain. The unique design of the POLIFAN® STRONG flap disc provides the maximum metal-removal and longest tool life of any flap disc.
