How to use: For cutting rivets, bolts, and nuts, just position the cold chisel on the target and give it a good strike. To remove pins and rivets, use the pin punches. Mark center lines and drill starting points with the center punch. The long taper punch is for installing and removing pins and shafts. And use the starter punch to start and install pins and rivets. Note: Always wear safety goggles when using these tools. Make sure the striking end of the chisel is in good condition. Maintenance: After use, clean the tools with a dry cloth. Store them in a dry place to prevent rust. Check the ASME B107.47 standard for any additional care instructions.
