This is the best quality made in the USA dimple die available. It is CNC machined from 4140 alloy steel and then heat-treated for hardness. Install with a hydraulic press, bench vice, or an impact gun using the nut and bolt included with the kit. Rated for 18 gauge mild steel (cold finish) max.
NOTE: Do not press on the bolt
If using an impact gun the bolt will only withstand the tensile strength for a few installations. Additional bolts will be required.
