TapeTech EIFSand™ Tungsten Carbide EIFS Rasps provide a high removal rate and long life; more than 100 times longer than standard abrasive rasp paper! Their hard and durable tungsten carbide composition removes EPS/XPS Foam quickly and easily. The rounded corner design prevents gouging. The ergonomic handle and knob grip design reduces hand fatigue and allows the worker to easily sweep the tool on the wall to achieve a flat surface across larger areas.
