The push-to-fit design with a flexible stem helps keep the soft foam tip clean, even when hands are dirty, since there is no need to roll the foam before fitting.

Recommended applications include assembly and mechanical, chipping, chiseling, cleaning, drilling, furnace operations, grinding, heavy equipment operations, machining, metal repair, painting, pouring/casting, power fastening, riveting, sanding, sawing and welding.
