Everything shown in first image. Dies are CNC machined from premium SAE 8620 steel with a Rockwell hardness of 80. These dies are great for virtually anything you can dream up. Common uses are : -Providing rigidity to sheetmetal projects. -Lightening up builds -Dimple die skid plates-front bumper plates-floorboards-foot pedals-footrests and many more uses. -Use the raised side of the dimpled material for added traction on running boards and floorboards. -Or just use them to add that extra RAD look to any project !!!!! More Details: Made for use with a hydraulic press or arbor press. 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-that's your final call. We recommend lubricants when using the dies.This will reduce die wear and gulling. general die information: 1/2". =7/8" Flare-1-1/4"Die OD 3/4". =1-1/8" Flare 1-3/8"Die OD 1". = 1-1/2"Flare 1-7/8"Die OD 1-1/4"= 1-7/8" Flare 2-3/8" Die OD 1-1/2"= 2-18" Flare 2-5/8" Die OD 1-3/4"= 2-1/2" Flare 3-1/8" Die OD 2" = 2-3/4" Flare 3-3/8" Die OD 2-1/2"=3-1/2" Flare 4-3/8" Die OD 3"= 4-1/8 " Flare 5-3 /8" Die OD
