I need to mill a 1/2" key slot in a 2" hardened splined shaft. Will carbide cut through the hardened shaft?
Thanks in advance,

Chuck,
I wonder why a shaft with splines would need a key installed?

The whole point of hardening stuff is so that it can't be cut, doh!
You may as well anneal it and and re-harden it after cutting the keyway. If you go ahead and cut the keyway with kryptonite or whatever it will get so hot it will be annealed anyway so you may as well do it in a controlled fashion.
I just had to cut some 10mm x 5mm deep blind keyways in 6 Thomson case hard shafts,above 60 Rc.I pre drilled with a carbide drill to depth then plunged and milled with an OSG Exocarb end mill.They are advertised to cut 70Rc,however MSC cost was over $100.00 for the mill,which I managed to destroy by recutting chips.I was going to post and ask I anyone had any better ideas or better tool sugestions.I had tried an Atrax uncoated endmill but it dulled right away.
