These Osborne setting dies are made of superior-grade steel. Use for installing #6 rolled rim grommets and spur washers by hand.
Product Note: Setting dies are guaranteed against defects in material and craftsmanship, but this guarantee is not intended to include tools against wear and tear, over-strain, and steel hammering. To achieve maximum life of tools, use a rawhide mallet or maul, dead blow hammer, and cutting pad . Strike at a 90-degree angle.
Product Note: The male sits higher on the base. This gap prevents the teeth on the spur grommets from getting crushed when set.
