PFERD TOOLS Advance Brush unthreaded crimped wire wheel offers medium face wheels in carbon steel filaments. Medium face brushes are designed for medium to heavy duty use either individually or gang mounted. As with all PFERD Advance Brush crimped wire wheels, the metal components and adapters are designed for a flush fit when gang-mounted. This design ensures a consistent, seamless surface finish. 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. Tough, cost-effective wire with high-tensile strength recommended for high speeds and long service life. Crimped steel wire is best for light surface work and for removing rust. Used in automotive, transportation, mining, electronics, aerospace, welding, nuclear, textiles, food services, construction, petrochemical, farming, medical, shipbuilding, fabricating, defense, foundries, and plastics industries. 1-inches width on arbor.
