| I order my cobalt-steel drill bits from McMaster-Carr. The 1.55 mm (0.061" drill bits are $2.06 each in quantities less than 12. To put this in perspective, a local hardware store sells the same bit in high-speed steel for $1.43 each. It taked four of the steel bits to do what one Cobalt bit can do.
Typical of McMaster-Carr, if I order this evening (I did!), they will ship Monday and I'll generally have my order here in MA by Wednesday. By the way, if you order an item that is backordered, the order page gives you an estimated ship date.
JB Weld might be an option, but I've tried and had VERY good results with Locktite "green" compound in securing an aluminum center-hub to a steel mainshaft. The bond is so good that you can't pull or twist the parts apart. It takes the head from a soldering iron to break the bond. See my comments in my "Mainshaft Experiments" thread.
