Made of phosphorus bronze that is Factory Mutual approved, the bristles on these brushes inhibit sparking and are nonmagnetic and corrosion resistant. They satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present. The thick bristles are good for tasks such as removing weld slag, heavy surface contamination, and large burs.

Warning: Do not use in direct contact with acetylene.
