I did a search and could find this vise on the site so I thought I would throw it up. It's the Excel Swivel Head Pin Vise.
It fits all my drill bits and comes with four different vise heads. I reverse the bit so the cutting end is in the vise and end up with a perfect mandrel. I picked it up off of ebay.
Fits nicely in my hand and makes it easy to wrap coils. I've been using it for 1/6, 5/64 and 3/32 bits.
