Custom dimple dies + pictures
 

So as I promised to post this, here they are:

I'm proud to show my brain child:

Dimple Dies EVO II, 10 sizes, 1/2" to 3", integrated hole punch in every size, from Moc410M tool steel, heat treated to cutting tool specs
Rockwell scale: HRC56, should cut stainless like knife through butter.

I have to honest, I didnt make them, I desing them but my bubby did them with CNC-machine. I just deliveryd the steel rods for them.

Some are still burn oil dirty, some I just sand blasted cleaner.

Each size has normal dies has hole, a pillow (the ring) and a cutting die has M10 threats so can be work with strong bolt or HF manual hydralic hole punch set with new center bolt.
That I've already bought.:cool:

Normal dies hole is used as a guide to guide rod that is threadet on the cutting die, it is in other side of the pillow when hole is made at the straight edge on other side of the pillow. If working with shop press, just need to drill hole so the guide bolt get through to cutting material to guide dies together.

Anyone getting this?

I could polish them, now just clean them. They are tools not jewelry.

Sweet!!!

It looks like a slick set up. Very Nice.

whos selling them for you?

Thank guys..

No one. Sorry...

I had them made for me by my friend.

They are really one-offs...

very nice. I have been thinking about making a few different sizes for a couple of projects.

gonna have to start makin some chips.

I sure would like to have some of those ..... :unibrow:

If you are not going to use a hydraulic ram on them, then the larger ones need a larger threaded hole. I think they need to be either 5/8" or 3/4" or you won't be able to get enough torque to punch through. Otherwise, nice! :thumbsup:

^ I know. That is only thing I would chance if I would do them again.

Would make threads to match hydralic punch rods.

Now they are so strong that cant make new threads.

I did use them on aluminium on fuel tank build. Made holes with shop press to baffles, they work'd great.
