4mm slot in Ti

[So not a Guru]

I have to cut a 4mm wide slot, 2.5mm deep, with 0.2mm fillets, in a few 6Al4V titanium parts. Does anyone have a tool recommendation for this?

Harvey tool.

I always like Harvey for small tools with corner radii.

Here is another option, with Thru-coolant, if that is an option. Mikron makes great tools, but you've got to be careful on availability. I know the tools are made outside of the U.S., and they don't always keep everything in stock. That is a place where Harvey really shines. Unless you're ordering large quantities of tools, they usually have every tool in their catalog in stock.

Mikron Tools are made in Switzerland and German as far as I know. They are not cheap but worth it if you need small tools for difficul materials.

Another vote for the Mikron, if the Harvey doesn't do the job.  They're amazing tools for deep slotting.  The ones with the coolant jets just above the flutes are pretty crazy.
