Here is a really nice indexable endmill that can stand up to the hard stuff.
This is a very nice heavy duty cutter.

Uses 5 TPU-332 carbide inserts (INCLUDED, I ALSO HAVE EXTRA INSERTS FOR SALE.IF YOU WIN AUCTION AND WANT EXTRA INSERTS, I WILL SHIP FOR SAME PRICE)

Wrench for changing inserts.

No need to use one of your endmill holders with this one.Ready to go with the R8 shank.

SATISFACTION GUARANTEED OR YOUR MONEY BACK!!!!!!!!!!
