Source for Pin Vise Drill Bits

I have a set of #61-80 pin vise drill bits but can't find a source for sizes #54-60 without the vise itself (I have two already). A few modeling books mention several applications for a size #54, so you'd think they'd be sold somewhere.

Ace Hardware, Micro Mark and the local hobby shop don't carry them. M.B. woo woo woo does sell a set of #52-70 for $12.59, but I'm hoping to avoid paying shipping costs that approach the item cost. Also, Amazon sells several sets, but they're measured in mm rather than the traditional numbering system. Is there a conversion chart somewhere?

Any leads appreciated.

 

Well,

A member sent me a PM with the link to these bits at Micro Mark. Many thanks.

 

These may be worth a look - I've used them for years = https://www.banggood.com/150pcs-0_4...=105229698&sc_uid=14j3s5xNiU&cur_warehouse=CN

Thanks. That should be helpful.

 

Here is another site with wire size drills, as well as sets. https://www.widgetsupply.com/category/dremel-drill-bit-wire-gauge.html

 

Thanks for the link to Widget Supply. Looks very useful.

 

You can waste a BUNCH of time looking thru the WIDGET SUPPLY website! LOL But they do have a lot of hobby supply items and good prices. I've been a customer for years.
