Dimple Die Set 3 Piece Set 1/2 3/4 1 metal fabrication tools hole flares

3 piece set includes: 1/2"(.500) 3/4" (.750) 1" (1.00) Made for use with a hydraulic press or arbor press. There are no holes in the middle of these dies. Holes must be drilled before you dimple the materials.(These do not act as punches) We recommend no thicker than 1/8" material. Customers have done thicker-thats your final call. We recommend lubricants when using the dies. This will reduce die wear and gulling.
