Given that you can buy top quality M2 end mills for $1.50 up [see
http://www.wttool.com and many other sites ] it no longer pays to
get these sharpened.
I have tried "generic" endmills from enco and they leave a lot to
be desired. I have good luck with "quality imports" from various
places. I have been surprised to find some of these come from Japan,
some come from korea but I don't think any have come from china.
I bought some plain milling cutters from enco and they work well.
Made in poland I think.
I bought high quality carbide endmills from grainger in a
pinch and I am still using some of them after 8 years. Hard to
believe any cutter lasting that long, expecially since these
were the first endmills I ever bought and used only
on my sherline mill. I just used one last weekend to cut a lot of
416 stainless steel.
Enco regularly have name brand endmills on sale. I just bought
some small carbide endmills for about 5 bucks each. For a couple
bucks more, they have double ends.
I will have to check out wttool. thanks
