PFERD stem mounted power wire cup brush. Cup brushes are built with high quality components that are designed to perform in welding and industrial applications and use on easily accessible and level surfaces. Great cutting action and flexibility, excelling on large flat and curved surfaces. For optimal brushing action, tilt the brush between 15 and 30 degrees off of the workpiece surface. Gray carbon steel wire provides excellent abrasion and wear resistance, along with high flexing action. High strength filament able to remove heavy buildups. Good bend recovery. For weld and mold cleaning, light deburring, rust, paint and flash removal. Recommended for use on portable power tools to remove paint, burrs and corrosion. Uses in industries area: automotive, transportation, mining, electronics, aerospace, welding, nuclear, textiles, food services, construction, petrochemical, farming, medical, shipbuilding, fabricating, defense, foundries and plastics.
