Just go into the MSC cataloge, they have an online store called mscdirect. Look on page 433 in the browse the big book section. You can order a high speed tool bit at what size you want. The kind used for lathes. Should be around 5 bucks. It will be square or round, and then grind it on a grinding wheel. Have some water handy to dip it in because it will get hot. Make the tool with the proper relief's and you are in buisness. Very simple to do. I use a carbid tool bit also but you need a diamond wheel to grind. If you need any help grinding just ask. Paul
