iono... cutting slow can have it's disadvantages, as i found out. I'm trying to cut some fins with a 1/16" bit, first I cut about 2-3 mm deep, and cut fairly quickly, and got through 6 fins before it broke. I read this post, and tried cutting slower. I cut about .25 mm deep, at about .05mm / second accross.I got through 2 fins (cutting them another 2 mm deep each) before it got too dull.

So basically you want to cut as quickly as you can without them breaking to get the most out of the bits. I've pretty much had enough of endmills, and am going to go with dremel diamond cutoff wheels. 6 for $10, and a lot quicker.
