Change the faces out when worn rather than replacing the entire tool. A fluorescent orange color makes these mallets easy to see. All have a head loaded with metal shot for added weight and a controlled impact with minimal rebound. Use them to drive chisels and strike work without damaging its surface. Often used on plastic, wood, and sheet metal, the polyurethane rubber faces resist oils and solvents and won't crack under high impact. The medium-hard face has a hardness similar to that of a plastic cutting board; the extra-hard face has a hardness similar to that of a hard hat. Use a face that's softer than your workpiece to avoid marring. Lighter weight mallets are good for tapping work into place and driving a chisel to make small cuts. Choose heavier weight mallets for assembling joints, dislodging stuck parts, and making aggressive cuts with a chisel. Longer mallets allow for more powerful swings. A textured grip provides slip resistance.
