With the Norton Aircool backing pad, you grind metal quickly, accurately, and efficiently. The ventilated airflow design actively draws heat away during heavy-duty grinding, preventing abrasive loading and extending the service life of your fibre discs. This protects workpieces against burn marks and discoloration during deburring, weld blending, and rust removal. Featuring a medium-density rubber construction, it provides the ideal balance of firmness and flexibility to smoothly follow flat surfaces and contours for a consistent finish. You can secure this 125 mm backing pad directly onto any standard angle grinder equipped with an M14 spindle.
