1/4" high feed mills with CTS

[So not a Guru]

Anyone have a source for these? We've been using the Helical ones and they work fantastic, but they have been out of stock for over a month and our vendor has no idea when they'll be available again. Looking for something comparable to these:

Iscar, Ingersoll and Harvey come to mind.

1/8" to 1/2" high feed end mills.

Emuge has small high feed mills. They gave me a 1MM high feed mill. I looked at it under a microscope and sure enough. I thought they were crazy. I ran it in 304 stainless at a .004" DOC and 80 IPM. Cut beautifully.

What feeds and speeds?

Even in 304SS, the RPMs must have been crazy fast

I did not have a crazy fast spindle. I think it was 12K. But of course, with AICC turned on, the feed only got to 80 IPM for moments at a time.

Sorry guys, I lied, (mistaken). It was a 2MM High Feed Endmill.

I'm liking their selection, thanks for the tip!

I don't see any speeds, feeds & DOC info on their site. Am I just missing it?

Today feels like a Monday so I apologize for this mistake. These were Seco Tools. I went to my stash to double check. It's been about 5 years since I did this.

Seco HF Endmill 980010-MEGA    This is a 1MM endmill and they go up from there. Sorry if I wasted your time.

Paul, thank you for digging it up and proving good information. I learned something i was not even aware of.

I gotta admit, I ran these tools with much trepidation. But, I was amazed at how well they ran. The picture I posted above should have had those pockets all the way around but the stock the customer sent me was bowed almost an 1/8". I had no way to hold them except to clamp them right to the machine table. I have a magnet here but wouldn't work with stainless. Customer just wanted to see if the tools would hold up at 12K RPM. He was happy but opted for the 15K optional spindle.
