If you are grinding into aluminum or brass, and having clogging issues, you are likely doing one (or both) of 2 things wrong. Wrong burr (highly likely) and lack of lube (highly likely)
It is possible to use a conventional carbide with more "tpi", but not the most appropriate many times. Add some wax, antiseize, grease, or dupont teflon drylube to the burr. Some lubes are messier than others, some lubes last longer than others. Finishes may also vary. Do your own experimenting.
