Guys, please help me find some end mills with the following specs;

Material: HSS
Flutes: 2
Cutting diameter: 1/8"
Shank diameter: 3/16"
Other: Center cutting - preferably double ended - less than $5.00 each

I do have the above in end mill sets but need several of this one size.
This is for cutting 1/16" 6061/6063 aluminum.
Why do you want to run small HSS end mills? They are horrible. I use a lot
of 1/8" solid carbide end mills, they work WAY better than HSS. You can
watch the tip of the small HSS enc mills wandering around, the tool
deflection can equal the tip diameter in some cases. Makes horribly
inaccurate work.

I'm a newb to milling, but I'm certain that if you push a small
diameter milling bit to deflect by more than its own diameter, you're
pushing it -way- beyond the proper feed speed. Slow 'er down, duuuude.


If you are pushing a carbide endmill and have more than a grand or so
deflection..you have a broken endmill. They are tough..but they are
brittle as hell.

Correction..more than a couple tenths deflection with carbide...Snap!!


Which is why good grades of carbide..like those from Harvey..cost more
than $4.50 HSS from the Hobbyshack
