I use these for milling aluminum. I do small steps of around 0.2 mm and have yet to dull them. So far I've only had to replace them when I do something dumb that causes them to snap. They've lasted at least 15 hours of milling.

I’ve used this brand before and they’ve been okay. They don’t last very long but fairly cheap so not a huge deal. The HUGE deal is the last package I got cuts NOTHING because all they do is break. I slowed things WAY down - though why when I’ve cut at the same speed and depth for hundreds of projects with no issues - and that didn’t help. Ordered different ones from a different supplier - maybe THAT will help.EDIT - Bought two packages. One package only broke, the other package can’t make a clean cut even with the FIRST use. So much time and money wasted. 😩 Picture shown is with a BRAND NEW bit. Never been used.

Leaves a very jagged edge on the material you're cutting. Not sharpened properly? I've tried it on wood, acrylic, copper, and aluminum. No go on any of them. I'll go back to my more expensive bits.

El filo de corte es largo y por lo tanto un poco menor el avance de corte ....si fuera un poco menor el filo estaria perfecto
