Overview
The UNCO- RMXI005U340 is a punch tool weighing 0.06 kilograms, about 2 ounces, making it one of the lightest tools in its category. Its size and weight point to a small precision punch rather than a heavy demolition tool.
At roughly 2 ounces, this is built for control in tight spots, such as marking, starting holes, or driving pins, rather than for heavy impact work. No material or length specs are listed, so the exact tip type and durability cannot be confirmed beyond its light weight.
