Hi all
I am having a hard time finding roundover (without bearings) bits for my machine. I came across Magnate bits that Legacy milling machines use.

http://magnate.net/index.cfm?event=showProductGroup&theID=240

Has anyone tried these bits and is there a better source for roundovers (without the bearing)?
I have tried Onsrud and Centurion and I can't seem to find what I am looking for. Onsrud offers a big selection of bits, but it's a chore hunting through all their products, they are not listed in any logical order that I can see, they seem to list in part number order. The Centurion website is easier to use, but doen't offer much more that straignt, fluted or sprial bits.
Thanks,
Jim

James, there is nothing wrong with removing the bearing and grinding the post off of any router bit. You may have to do a little measuring and trial and error cuts to establish the parameters for your tool path, but it will work just fine.

James, I had a legacy before my bot and a fairly comprhensive bit collection from them. They are carbide and used whenever I need or find a design that fits with the profiles I have. no complaints and they are farily reasonable for their unique profiles. The sharp tipped roundovers tend to burn the tips off so i would not recommend high speed cutting RPMs with those. the flat tipped roundovers work nice to area clear and round the edges rather than a sharp straight end mill cut edge.
I dont think you'll be disappointed.

James,

One of our fellows is a Onsrud dealer who has special bits just for 3D and regular routing.
