Non-sparking, corrosion-resistant pneumatic machine chisels from CS Unitec are used for breaking or chipping concrete, asphalt or soil with paving breakers and other demolition tools. Manufactured from copper-beryllium or aluminum-bronze alloys, they are designed to eliminate spark risk at sites where explosive atmospheres may be present. They meet OSHA and ATEX regulations for safe use in areas where hazardous, flammable or combustible vapors, liquids, dusts or residues may be present. They are laser-engraved to indicate where each can be used safely. Paving breaker tools include bull points for breaking concrete and 3-inch-wide chisels for softer material with deeper penetration in both 1 1/8- and 1 1/4-inch hex shanks. 800/700-5919; www.csunitec.com.
