Made in the USA out of domestic steel, these dimple dies come with a life time warranty. You split them in half and we will replace them free of charge. It's that simple. These dimple dies are CNC machined out of 4140 quenched and tempered chromoly steel that has a tensile strength of 150,000 KSI. Each dimple die has a through hole drilled into both the male and female dies so they can be used in a few different ways.
The first method is they can be used in any H frame hydraulic press where the material you are dimpling is small enough to fit between the vertical frame rails of the press. Simply drill the appropriate size hole using an industry standard hole saw, then insert the male and female dies to the correct orientation then using the hydraulic cylinder, press the dimple dies down to flare the metal.
The second method is they can be bolted together using a standard off the shelf grade 8 fasteners 3/4" dia bolt or 7/16" dia bolt depending upon which dimple die size you have. This method is ideal for large pieces of metal that are too large to fit in a H frame style press, dimpling on a vehicle or dimpling after the fact... "Hey we should have put a dimple die there..." Well now you can with the through hole design that is standard on every die set we produce.
The third method is they can be pressed together using a 10 Ton Hydraulic Knockout Punch Driver as shown in the picture above. Not sure what one is? Check out Ebay or Harbor Freight, they sell for ~$100.00 shipped to your door step and they are a real time saver if you are dimpling a large number of items or hard to reach dimple die locations. It includes a manual hand pump to apply hydraulic pressure to the punch set. The knock out punch set is a quality product as we have dimpled thousands of holes for years using this set up.
Are you looking to dimple dies holes that are close together but not have them overlap? If so, you need to position them so the outside diameter will not interfere with the other dimple died holes.
The overall outside diameter of the dimple dies are as follows:
- .500" dimple die OD = 1.20"
- .750" dimple die OD = 1.45"
- 1.00" dimple die OD = 1.95"
- 1.25" dimple die OD = 2.40"
- 1.50" dimple die OD = 2.70"
- 1.75" dimple die OD = 3.17"
- 2.00" dimple die OD = 3.40"
- 2.50" dimple die OD = 4.20"
Please Note: We do not sell the knock out punch set or Air/Hydraulic foot switches, they are shown in the image gallery for reference only.
The dies themselves work great, unfortunately they don't work with the harbor freight hydraulic knockout driver. Either harbor freight changed their design or swag has the dimensions wrong, either way the shank isn't long enough to fit both dies and then get a nut on the end.
Great quality tools, make cool custom brackets and parts with these, definitely recommend
These dimple dies work great!
I successfully used the 1" die to flare the drain hole in my stainless steel plasma table pan. The tool's thru hole enabled me to utilize my Harbor Freight hydraulic punch to pull the dimple.
Excellently made products and perform perfectly!
