1/4 inch punch for mutliple layers?

[plinkercases]

I have a design for a sheath that needs several 1/4 inch holes and I was wondering if there is a punch that is more tubular for a greater depth. I.e. will punch multiple layers (I will use the arbor press) and keep the hole tubular rather than wider a the top due to compression outwards as the punch wall thickens.. I need a constant opening top and bottom as I then install a eyelet.

On the heaviest version I use 2 layers of 10-11 so total possible is equal to 20-22 oz.

Is there an off the self piece for is likely a custom made tool?

My other option to make a jig so if I punch the layers separately the holes are always aligned.

Thanks in advance for any experience or suggestions shared.

I would use a brad point drill, with the drill set for a slow speed.

I would use a drill bit, also.

Yup the brad point was one of my previous methods but for some reason I am adverse to drilling leather... but it is the best way to go then so be it.

Thanks folks.

The only thing with drilling is that you have to "clean" up the hole on the exit side after drilling...it usually comes out ragged.

Not sure if this will help but I often use hand punches in a hand battery drill when i have to get through rugged stuff and a lot of it.Leaves a nice clean hole when pushed into cutting board.When material is extra thick I just put the hand punch in drill and grind the outer of the punch down thinner whilst it rotates.

Good ideas folks thanks.
