try Busy Bee Tools for the HSS. Get HSS tool bits that they use in the metal
turning industry. They come in various square section bits about 2 1/2"
long. Busy Bee will sell you one or fifty without breaking a sweat. If you
are in the States try Enco. I think the urls are
http://www.busybeetools.com and
http://www.use-enco.com
If wrong a Google search will point the way. One of these days I have to put
up a links page.

Merry Christmas to all and to all a good turn(ing)
