Good job.
I have just received a 30 ton hydraulic punch which puts a 20mm hole in 8mm mild steel. The only reason I purchased it was because it was cheap, $114 AUD new, and came with 4 dies. I have some square dies on order which will make it MUCH more useful.
It's so quick, easy and cheap to drill round holes of almost any size ... I'm curious to know the reason for making your punch Michal ???

I generally just use a "Whitney punch"

What do you plan to use the square dies got and do you have a link to them.

Thanks

Here's the link to the original equipment, price has risen and you need your own pump

I'll look for the link for the square punches and dies. I use square holes to prevent the head of coach screws from turning. As you will know it's very difficult to make square holes in steel any other way.

And you can buy square punches and dies from here

It's a UK site for a vendor Chinese and you'll pay in UK pounds. I purchased 8, 10, 12 and 14mm sizes, which were all the same price, about £11 each, post free.

Good job.

On You Tube he mentions he has to make thousands of 4mm holes in 1mm thick stainless steel! Agree, the punch definitely the way to go.
