Niagara Multi Flute with or without Chipbreakers
Chipbreakers reduce the length of the stringy crappy chips, reduces tool pressure for more feed rates, and helps the conveyors stop getting chunked up.
Call me for pricing.
UPS RED NEXT DAY shipping on ALL Niagara items is only $16.50
Best for the Money.....no doubt. Made in USA

what would be an optimal feed and speed and doc for 1.4301 stainless steel in a fanuc robodrill with 12mm (half inch) end mill?
is there a good online calculator which can "tell me" that?
I would like one which takes many things in consideration for example how much the tool is pulled out of adapter, or how long it is, the size of part (vibrations due to longer and slimmer parts), etc.
I was breaking tools in that material like crazy, but at first i used 6mm end mills.

I have used Widia, Kennametal and Monster.
All in the same Tialn coated HP 4 variable flute desing.
Widia performed better than anything else and was actually cheaper. Kennametal OK but did not last as long.
Monster was cheapest and didn't last at all. I could tell it would not just by looking at its flutes.

For the money , I like the garr vrx and v4 series. I think a lot of it depends on a vast combination of things though. Machine, fixture, tool holders, tool paths, controller,operator,my luck that day, etc etc

My recommendation is IMCO M525 series. Their 5 flutes will beat anyone out there. I've tested them all. But you need to run at their speed and feeds and dont plug and play with whatever you're using now.

I launched a buying site last year just for variable helix tools, 4 and 5 flute for steels.
It also features Zrn coated tools for aluminum, but they're not variable helix. (working on that..)

Many moons ago, before Frank Mari sold HTC's, I put HTC's heads up against
the Hanitas.. The HTC ran 70 parts before it started to get a little loud.
Then came the Hanitas.. Of the 3 I got to test, not a one of them completed
3 parts at the same speeds and feeds, and even the same holder.. Put in another
HTC and ran out the remaining 70 something parts, and the endmill lived to cut again.
Hanita tech told me I had to lower my surface speed, and my chip load for the privilege
of paying more(A LOT MORE$$$$) for their endmills.
The HTC's, Imco's and Titans, in my experience are all pretty darn close. The times
I've had enough run time to gather data, they are within 4 or 5% of each other.
I'll vouch for Curtis's Titans to be vastly superior to the Hanitas. Never run SGS, so
I can't say. And Curtis is a good guy too, he's helped me out a lot and never steered me wrong.

price is probably about $120, and most sane places will sell them for $75 maybe...
It also wouldn't surprise me if they have changed... They had tons of stupid reliefs and steps and shit
in the flutes that served absolutely no purpose in the cutting process.. On the constant occasion that
you broke them, it wasn't hard to see why, all the fancy "pretty" grinding left absolutely NOTHING for
a backbone.. There was more meat in the center of a standard 1/4" endmill than in the center of a 1/2"
Hanita varimill. They sure were pretty though.
On the positive side of the Hanita Varimill. Back in 2005 or 6 I grabbed a pile of uncoated 1/2"ers off
of J&L's O-Zone for about $20 each.. Apparently they were going to stop stocking them uncoated.... I ran the hell
out of those in a ton of aluminum bronze.
