Killing 3/32" endmills?

[dertsap]

most of the problem is the inferior cutter ,its rediculous to have to run so slow ,you can be sure that if someone puts those cutters on ebay , they bought them for next to nothing , sold them to you for a little more than next to nothing , how many hands have these tools been thru ? they were probably made for pennies in china , products are concidered made in america if they are assembled here , like putting tools in a box for example , bottom line is you get what you pay for ,if you pay 2 or 3 dollars more for a decent tool ,you will see the difference
its the equivelant from spam to tenderloin , sure spams cheaper but it tastes like crap
brass cuts very easily , but running it at .0005 your only going to dull your tool because brass is very abrassive , at 6700 rpm you should be running at roughly 15 ipm with a four flute minimum, if your plunging you would be better off with a slot drill ,because these are made for it , an endmill is not designed to plunge , even though we may do it at times

the noise and the burred looking hole get me
is there clearance on the front of the tool?
is the tool resonating ?(flexing spirally)
are the cutting edges equal size and angle?
sounds like junk cutters
like most things you get what you pay for

I'm pretty sure it's the cutter. I can run any other size or number of flutes without trouble. For the most part, I pay around $4 each for these little cutters and this batch was just bad. But overall, I can't complain. I've got twenty hours now on the 1/16" that I said I had fifteen on a couple of days ago - and it's still going strong. I just can't bring myself to pay tons of money when a little bargain basment shopping and an occasional bum cutter is the only price I pay

dude for those little cutters you'll be surprised the difference in price between good ones and not so good of ones , not much , and things go far smoother , if you break two cheap cutters so what , but you could have bought one good one and if its run properly it won t break , its all about saving the grief

someday i should follow my own advice , i ve got two of everything in my workshop ,one good one and one broken cheap piece of crap
