The punches are made from aircraft grade chromoly 4130 steel and heat treated to last. A 5 degree bevel cutting face on the punches for easy sharpening, if ever needed.
The punches and dies can be interchanged for each coin if different sized holes are desired in the coins. The punch sizes are 3/8″, 7/16″ and 1/2″. The housing has been zinc electroplated to resist rust, knurled top and bottom for ease of tightening and a quick thread pitch to lock down the coin quickly and tight. Comes with the housing and three sets of punches, dies and zinc electroplated spacers for U.S quarters, halves, and Morgan dollars only.
Always wear safety glasses when using this punch/die set and a brass hammer.
