hole punch for tobacco tin ideas please :) ?

[Fivetide]

I am aiming to do quite alot , the drill I have tried it tends to tear the metal and because its PCB mounted equipment I want it quite precise so it looks good.. i have looked at a numatic set of rams , but i want something simple to start with.

Have a look on the web for a Whitney hand punch, I have an old one that goes to 1/4", does 16swg steel ok but you should centre punch first to get a good location.

Just had a look on the web and they appear to be quite expensive! But they do work!!

To drill holes in thin sheet steel as others have said sandwich between to pieces of wood but main thing is do not use a normal jobbers drill but grind one up like a wood bit as a wing and spur.
If you have decent wood bits you could just use one of these but most i have come across aren't even hardened hence the grinding up of the wing and spur.

Worth keeping a few as they are also ideal on plastics and prevent splitting as they exit the hole.

therefore maybe something like these at the right speed...

Dremel Brad Point Drill Bit Set - 631 | eBay (they go up to 1/4")

never used them for tin, but they work great on acrylic! (& handy to have in your arsenal of bits - especially if your machine is confined/restricted to a 1/8" collet, such as a rotary tool in this arrangment - https://www.google.co.uk/shopping/pr...g&ved=0CCAQrRI)

I want to avoid drilling if I can , I want a sort of high bred clamp come punch template combo , ill work on it and see what I can do, thanks for the replies guys :)

Hi Fivetide
regarding die press, a decent pillar drill should provide enough pressure for punching thin stuff,clamp your die to the table (simples)
