I'm looking for some very small end mills from around about 3/64 to 3/32. Are they still called end mills at this size or are they just hard to find? I'm finding a few but not many, I'd really like to find a set if possible but don't mind buying individually.
 
Don't know where you're looking but they are commodity items and widely available.

Expect solid carbide in that size range.

Maybe that's the problem. Are you looking for HSS? :confusion:

Google "3/64 end mill": https://www.google.com/search?source=hp&q=3/64+end+mill&oq=3/64+end+&gs_l=psy-ab.1.0.0j0i22i30k1.3969828.4085873.0.4087632.12.12.0.0.0.0.287.2053.0j3j6.9.0....0...1.1.64.psy-ab..3.9.2049...0i131k1j0i22i10i30k1.0.Z1KyyFopA8A
And they break easily so buy many at once of the same size you need.
Everytime you look at them wrong ... snap.
 
If your mill does not have the correct speeds for that size of end mill, don't even start the job... For instance, for aluminum, 3/64" cutter, 400 SFPM, you would be looking at 31,000+ RPM! The feeds also have to be correct. Get either wrong and buying cutters by the gross will not help a bit.
 
Aaron what type of work are you trying to do and what are the materials you wish to machine.

He did not ask how to use them just where to buy them :)-

Using them effectively is a whole nother story.
 
I use smaller than those you are looking for. I use daily 0.012" and 0.020" 2 fluke miniature end mills from MSC, see page 433 in their catalogue for more of their Accupro line. Spindle spins at 60K and feed at 30" per minute for the 0.020 and usually 15" per minute with the 0.012" bits. Both are the stubby version, only 1.5X length to diameter. Standard 3X LOC will not survive with these settings. This is in a CNC set up not hand fed.
BTW the Micro100 end mills are better but actual cost in use is higher than the MSC versions.
